# 10 - Air Law > Source: exam.quizvds.it (EASA ECQB-SPL) | 84 questions --- ### Q1: Which area could be crossed with certain restrictions? ^q1 - A) No-fly zone - B) Restricted area - C) Prohibited area - D) Dangerous area **Correct: B)** > **Explanation:** A restricted area (designated "R" on charts) can be entered subject to specific conditions published in the AIP, such as obtaining prior clearance from the responsible authority or ATC unit. A prohibited area ("P") cannot be entered under any circumstances — flight within is absolutely forbidden. A dangerous area ("D") contains hazards to flight but has no entry restriction; pilots are warned but may enter at their own discretion. "No-fly zone" is not a standard ICAO airspace classification per Annex 11. ### Q2: Where can the type of restriction for a restricted airspace be found? ^q2 - A) AIC - B) ICAO chart 1:500000 - C) AIP - D) NOTAM **Correct: C)** > **Explanation:** The Aeronautical Information Publication (AIP) is the primary official document containing detailed and permanent information about airspace structure, including the conditions, times of activity, and authority contacts for restricted areas (ENR section). While NOTAMs may announce temporary changes and ICAO charts show boundaries graphically, the authoritative definition and restrictions are found in the AIP. AICs (Aeronautical Information Circulars) contain advisory or administrative information, not regulatory airspace details. ### Q3: What is the status of the rules and procedures created by the EASA? (e.g. Part-SFCL, Part-MED) ^q3 - A) They are not legally binding, they only serve as a guide - B) Only after a ratification by individual EU member states they are legally binding - C) They are part of the EU regulation and legally binding to all EU member states - D) They have the same status as ICAO Annexes **Correct: C)** > **Explanation:** EASA regulations such as Part-SFCL (Commission Regulation (EU) 2018/1976) and Part-MED are published as EU Implementing Regulations or Delegated Regulations under the Basic Regulation (EU) 2018/1139. EU Regulations are directly applicable law in all member states without requiring national ratification — they are binding in their entirety. ICAO Annexes, by contrast, are standards and recommended practices (SARPs) that require national adoption and allow states to file differences; they do not have direct legislative force. ### Q4: What is the meaning of the abbreviation "ARC"? ^q4 - A) Airworthiness Recurring Control - B) Airspace Rulemaking Committee - C) Airworthiness Review Certificate - D) Airspace Restriction Criteria **Correct: C)** > **Explanation:** ARC stands for Airworthiness Review Certificate, as defined in EU Regulation 1321/2014 (Part-M). It is issued after a periodic airworthiness review (typically annual) confirms that the aircraft's continuing airworthiness documentation and condition are in order. It accompanies the Certificate of Airworthiness and must be current for the aircraft to be legally flown. The other options are fabricated terms not used in EASA or ICAO aviation law. ### Q5: The "Certificate of Airworthiness" is issued by the state... ^q5 - A) Of the residence of the owner - B) In which the aircraft is registered. - C) In which the airworthiness review is done. - D) In which the aircraft is constructed. **Correct: B)** > **Explanation:** Per ICAO Annex 8 (Airworthiness of Aircraft) and Annex 7 (Aircraft Nationality and Registration Marks), the Certificate of Airworthiness is issued by the state of registry — the country where the aircraft is registered. The state of registry is responsible for ensuring the aircraft meets applicable airworthiness standards. This is separate from the owner's residence, place of manufacture, or where maintenance is performed. ### Q6: The validity of a medical examination certificate class 2 for a 62 years old pilot is... ^q6 - A) 12 Months. - B) 48 Months. - C) 24 Months. - D) 60 Months. **Correct: A)** > **Explanation:** Under Part-MED (Commission Regulation (EU) 1178/2011), a Class 2 medical certificate for pilots aged 40 and over is valid for 24 months — except for pilots exercising privileges to carry passengers, where validity is reduced. However, for pilots aged 50 and over (and particularly 60+), validity is reduced to 12 months regardless. At age 62, the Class 2 medical is valid for only 12 months. This reflects the increased medical scrutiny applied to older pilots. ### Q7: What is the meaning of the abbreviation "TRA"? ^q7 - A) Transponder Area - B) Temporary Reserved Airspace - C) Terminal Area - D) Temporary Radar Routing Area **Correct: B)** > **Explanation:** TRA stands for Temporary Reserved Airspace — airspace of defined dimensions within which activities requiring reservation of airspace are conducted for a specified period. TRAs are used for military exercises, aerobatic displays, parachuting, or other temporary activities. They are published via NOTAM and activated as needed. They differ from TSAs (Temporary Segregated Areas) in that TRAs may be shared with other traffic under certain conditions when not active. ### Q8: What has to be considered when entering an RMZ? ^q8 - A) To obtain a clearance to enter this area - B) To permanently monitor the radio and if possible to establish radio contact - C) To obtain a clearance from the local aviation authority - D) The transponder has to be switched on Mode C and squawk 7000 **Correct: B)** > **Explanation:** An RMZ (Radio Mandatory Zone) requires all aircraft to carry and operate a functioning radio, to monitor the designated frequency continuously, and to establish two-way radio contact with the responsible ATC unit before entry if possible. It does not require a formal ATC clearance (unlike a CTR). A transponder is not mandated by RMZ designation alone — that is required in a TMZ. This is defined in SERA.6005 and national AIP supplements. ### Q9: What is the meaning of an area marked as "TMZ"? ^q9 - A) Transponder Mandatory Zone - B) Transportation Management Zone - C) Touring Motorglider Zone - D) Traffic Management Zone **Correct: A)** > **Explanation:** TMZ stands for Transponder Mandatory Zone — airspace within which all aircraft must be equipped with and operate a pressure-altitude reporting transponder (Mode C or Mode S). This allows ATC and other aircraft (via TCAS/FLARM) to identify and separate traffic. TMZs are often established around busy airports or in complex airspace. Glider pilots must be aware that many glider airfields and soaring areas are now overlaid with TMZs requiring transponder equipment. ### Q10: Two engine-driven aircraft are flying on crossing courses at the same altitude. Which one has to divert? ^q10 - A) Both have to divert to the left - B) The lighter one has to climb - C) The heavier one has to climb - D) Both have to divert to the right **Correct: D)** > **Explanation:** Per SERA.3210, when two aircraft are on converging courses at approximately the same altitude, each shall turn to the right. This creates a situation where both aircraft pass behind each other, avoiding a collision. Weight is irrelevant to right-of-way rules in crossing situations. The "give way to the right" rule applies to converging (not head-on) situations; in a head-on encounter, both aircraft also alter course to the right (SERA.3210(c)). ### Q11: Two aeroplanes are flying on crossing tracks. Which one has to divert? ^q11 - A) Both have to divert to the lef - B) The aircraft which flies from left to right has the right of priority - C) Both have to divert to the right - D) The aircraft which flies from right to left has the right of priority **Correct: D)** > **Explanation:** Under SERA.3210(b), when two aircraft are converging at approximately the same altitude, the aircraft that has the other on its right must give way. This means the aircraft approaching from the right has right-of-way (i.e., it flies from right to left relative to the other aircraft). The aircraft that sees the other on its right must alter course — typically to the right — to avoid a collision. This is the "right-of-way" rule analogous to maritime rules. ### Q12: What is the minimum flight visibility in airspace "E" for an aircraft operating under VFR at FL75? ^q12 - A) 8000 m - B) 1500 m - C) 3000 m - D) 5000 m **Correct: D)** > **Explanation:** Per SERA.5001, in airspace class E at and above 3000 ft AMSL (or above 1000 ft AGL) and below FL100, the minimum flight visibility for VFR is 5000 m (5 km). FL75 is approximately 7500 ft, which is above 3000 ft AMSL but below FL100, so the 5000 m rule applies. The 8000 m minimum applies at and above FL100. The 1500 m minimum only applies at or below 3000 ft AMSL/1000 ft AGL in airspace F and G. ### Q13: What is the minimum flight visibility in airspace "C" below FL 100 for an aircraft operating under VFR? ^q13 - A) 1.5 km - B) 8 km - C) 5 km - D) 10 km **Correct: C)** > **Explanation:** Per SERA.5001, in airspace class C below FL100 (and above 3000 ft AMSL or 1000 ft AGL), the minimum VFR flight visibility is 5 km (5000 m). The 8 km minimum only applies at and above FL100. The 1.5 km minimum applies in uncontrolled airspace at low altitudes. Glider pilots operating in class C below FL100 — for example crossing an airway — must ensure at least 5 km visibility. ### Q14: What is the minimum flight visibility in airspace "C" at and above FL 100 for an aircraft operating under VFR? ^q14 - A) 1.5 km - B) 10 km - C) 5 km - D) 8 km **Correct: D)** > **Explanation:** Per SERA.5001, at and above FL100 in controlled airspace (including class C), VFR flight requires a minimum flight visibility of 8 km. This higher threshold reflects the faster speeds and reduced manoeuvring margins at higher altitudes. The 10 km option is not a standard ICAO/SERA VMC minimum. The progression to remember is: low altitude uncontrolled = 1.5 km, controlled below FL100 = 5 km, at and above FL100 = 8 km. ### Q15: The term "ceiling" is defined as the... ^q15 - A) Height of the base of the highest layer of clouds covering more than half of the sky below 20000 ft. - B) Height of the base of the lowest layer of clouds covering more than half of the sky below 10000 ft. - C) Height of the base of the lowest layer of clouds covering more than half of the sky below 20000 ft. - D) Altitude of the base of the lowest layer of clouds covering more than half of the sky below 20000 ft. **Correct: C)** > **Explanation:** "Ceiling" is defined as the height (not altitude) of the base of the lowest layer of cloud covering more than half the sky (i.e., more than 4 oktas — BKN or OVC) below 20,000 ft. Option A is wrong because it refers to the "highest" layer (should be lowest). Option B is wrong because the threshold is 20,000 ft, not 10,000 ft. Option D is wrong because ceiling is expressed as height (above ground level) not altitude (above mean sea level). This definition is from ICAO Annex 2 and SERA. ### Q16: A transponder with the ability to send the current pressure level is a... ^q16 - A) Transponder approved for airspace "B". - B) Mode C or S transponder. - C) Pressure-decoder. - D) Mode A transponder. **Correct: B)** > **Explanation:** Mode A transponders transmit only a 4-digit identity (squawk) code. Mode C transponders add pressure altitude reporting — they encode and transmit the pressure altitude from an encoding altimeter, allowing ATC secondary radar to display both identity and altitude. Mode S provides all Mode C capabilities plus selective interrogation, aircraft identification (callsign), and data link capabilities. Mode A alone cannot report altitude, so options A and D are incorrect. "Pressure-decoder" is not an aviation term. ### Q17: Which transponder code indicates a loss of radio communication? ^q17 - A) 2000 - B) 7600 - C) 7000 - D) 7700 **Correct: B)** > **Explanation:** The standard emergency transponder codes are: 7700 = General emergency, 7600 = Radio communication failure (loss of comms), 7500 = Unlawful interference (hijacking). Code 7000 is the VFR conspicuity code used in many European countries when no specific ATC code has been assigned. Code 2000 is used when entering controlled airspace from uncontrolled airspace without a prior assigned code. In a radio failure, squawking 7600 alerts ATC immediately to the communication problem. ### Q18: What is the correct phrase with respect to wake turbulence to indicate that a light aircraft is following an aircraft of a higher wake turbulence category? ^q18 - A) Caution wake turbulence - B) Be careful wake winds - C) Danger jet blast - D) Attention propwash **Correct: A)** > **Explanation:** The standard ICAO phraseology for wake turbulence warnings is "CAUTION WAKE TURBULENCE" — this is the prescribed phrase used by ATC when issuing wake turbulence warnings to pilots following heavier aircraft. ICAO Doc 4444 (PANS-ATM) specifies standardised phraseology, and non-standard phrases like "wake winds," "jet blast," or "propwash" are not ICAO-approved terminology. Standardised phraseology reduces ambiguity and is mandatory in EASA airspace. ### Q19: What information is provided in the general part (GEN) of the AIP? ^q19 - A) Table of content, classification of airfields with corresponding maps, approach charts, taxi charts, restricted and dangerous airspaces - B) Access restrictions for airfields, passenger controls, requirements for pilots, license samples and validity periods - C) Map icons, list of radio nav aids, time for sunrise and sunset, airport fees, air traffic control fees - D) Warnings for aviation, ATS airspaces and routes, restricted and dangerous airspaces **Correct: C)** > **Explanation:** The AIP (Aeronautical Information Publication) is structured in three parts: GEN (General), ENR (En-Route), and AD (Aerodromes). The GEN section contains general information including map icons/symbols, list of radio navigation aids, tables of sunrise/sunset, national regulations, fees, and administrative information. ENR contains en-route information including airspace, airways, and restricted areas. AD contains aerodrome-specific information including charts, procedures, and frequencies. ### Q20: Which are the different parts of the Aeronautical Information Publication (AIP)? ^q20 - A) GEN MET RAC - B) GEN AGA COM - C) GEN COM MET - D) GEN ENR AD **Correct: D)** > **Explanation:** Per ICAO Annex 15 (Aeronautical Information Services), the AIP is divided into three standardised parts: GEN (General), ENR (En-Route), and AD (Aerodromes). GEN contains general administrative and regulatory information; ENR contains airspace structure, routes, and navigation aids; AD contains information specific to individual aerodromes. The other options (MET, RAC, AGA, COM) are abbreviations from older ICAO documentation structures no longer used in modern AIP organisation. ### Q21: What is the purpose of the signal square at an aerodrome? ^q21 - A) It is an illuminated area on which search and rescue and fire fighting vehicles are placed - B) It contains special symbols to indicate the conditions at the aerodrome visually to over-flying aircraft - C) Aircraft taxi to this square to get light signals for taxi and take-off clearance - D) It is a specially marked area to pick up or drop towing objects **Correct: B)** > **Explanation:** The signal square (also called signals square or ground signals area) is a designated area at an aerodrome where ground signals are displayed using symbols, panels, or markings to communicate aerodrome conditions to pilots flying overhead who cannot receive radio communication. It is not a lighting area for emergency vehicles (A), not a location where aircraft receive light signals for taxi clearance (C) — that would be done by the control tower — and not a tow drop zone (D). ### Q22: How are two parallel runways designated? ^q22 - A) The left runway gets the suffix "L", the right runway remains unchanged - B) The left runway gets the suffix "L", the right runway "R" - C) The left runway remains unchanged, the right runway designator is increased by 1 - D) The left runway gets the suffix "-1", the right runway "-2" **Correct: B)** > **Explanation:** ICAO Annex 14 requires that when two parallel runways exist, both receive a suffix to distinguish them: 'L' for the left and 'R' for the right runway as seen from a pilot on final approach. Option A is wrong because the right runway also needs a suffix. Options C and D describe non-standard designations not used in ICAO procedures. ### Q23: Which runway designators are correct for 2 parallel runways? ^q23 - A) "26" and "26R" - B) "06L" and "06R" - C) "18" and "18-2" - D) "24" and "25" **Correct: B)** > **Explanation:** For two parallel runways, ICAO requires both runways to carry suffixes 'L' and 'R', resulting in designators like '06L' and '06R'. Option A is wrong because '26' has no suffix. Option C uses a non-standard dash notation. Option D shows different numbers (24 and 25), which would indicate two separate non-parallel runways on slightly different magnetic headings, not parallel runways. ### Q24: What is the meaning of this sign at an aerodrome? See figure (ALW-011) Siehe Anlage 1 ^q24 - A) After take-off and before landing all turns have to be made to the right - B) Caution, manoeuvring area is poor - C) Glider flying is in progress - D) Landing prohibited for a longer period **Correct: C)** > **Explanation:** The ALW-011 figure shows the international ground signal for glider operations in progress — a double-headed arrow or specific panel displayed in the signal square. This warns pilots overflying the aerodrome that gliders may be operating, including tow-launching and soaring in the vicinity. The other options describe unrelated signals: right-hand circuit (A), poor manoeuvring area (B), and landing prohibited (D). ### Q25: What is the meaning of "DETRESFA"? ^q25 - A) Distress phase - B) Alerting phase - C) Uncertainty phase - D) Rescue phase **Correct: A)** > **Explanation:** DETRESFA is the ICAO codeword for the distress phase, the most serious of the three emergency phases, declared when an aircraft is in grave and imminent danger requiring immediate assistance. ALERFA corresponds to the alerting phase (B), and INCERFA to the uncertainty phase (C). There is no phase called 'rescue phase' (D) as a formal ICAO designation. ### Q26: Who provides search and rescue service? ^q26 - A) Only civil organisations - B) Both military and civil organisations - C) Only military organisations - D) International approved organisations **Correct: B)** > **Explanation:** ICAO Annex 12 defines Search and Rescue (SAR) as a service that may be provided by both military and civil organisations, depending on national arrangements. Many countries use military assets (aircraft, helicopters, ships) alongside civil emergency services. Limiting it to only civil (A) or only military (C) organisations, or requiring international approval (D), does not reflect the flexible, nationally-organised nature of SAR. ### Q27: With respect to aircraft accident and incident investigation, what are the three categories regarding aircraft occurrences? ^q27 - A) Event Crash Disaster - B) Event Serious event Accident - C) Happening Event Serious event - D) Incident Serious incident Accident **Correct: D)** > **Explanation:** Under ICAO Annex 13 and EU Regulation 996/2010, aircraft occurrences are classified into three categories: incident (an occurrence other than an accident which affects or could affect safety), serious incident (an incident involving circumstances where there was a high probability of an accident), and accident (an occurrence resulting in fatal or serious injury, or substantial aircraft damage). The other options use non-standard terminology not found in ICAO definitions. ### Q28: During slope soaring you have the hill to your left side, another glider is approaching from the opposite side at the same altitude. How do you react? ^q28 - A) You divert to the right - B) You expect the opposite glider to divert - C) You divert to the right and expect the opposite glider to do the same - D) You pull on the elevator and divert upward **Correct: A)** > **Explanation:** ICAO rules of the air and SERA regulations specify that during slope soaring, when two gliders approach each other head-on, the glider with the hill on its right must give way — but in this question the hill is on YOUR left, meaning the hill is on the other glider's right. Therefore YOU must give way by diverting to the right (turning away from the hill). Expecting the other glider to divert (B) is incorrect because the rule is based on which pilot has the hill on their right. Pulling upward (D) is impractical and dangerous. ### Q29: Along with other gliders, you are circling in a thermal updraft. Who determines the direction of circling? ^q29 - A) Circling is general to the left - B) The glider who entered the updraft at first - C) The glider with greatest bank angle - D) The glider at highest altitude **Correct: B)** > **Explanation:** SERA regulations state that when joining a thermal already occupied by other gliders, the newly joining pilot must circle in the same direction as the glider that first established the turn in that thermal. This ensures all pilots orbit in the same direction, preventing head-on conflicts. Circling is not fixed as left (A), the highest glider (D) or steepest bank (C) does not determine the direction. ### Q30: Is it possible to enter airspace C with a glider plane? ^q30 - A) Yes, but only with transponder activated - B) No - C) With restrictions, in case of less air traffic - D) Yes, but only with approval of the respective ATC unit **Correct: D)** > **Explanation:** Airspace C is controlled airspace where ATC clearance is mandatory for all flights including VFR. A glider may enter Class C airspace only with an explicit clearance from the responsible ATC unit. A transponder alone (A) is not sufficient — clearance is the fundamental requirement. Option B (no entry at all) is too restrictive; entry is possible with proper clearance. Option C implies a discretionary traffic-density rule which does not exist. ### Q31: The holder of an SPL license or LAPL(S) license completed a total of 9 winch launches, 4 launches in aero-tow and 2 bungee launches during the last 24 months. What launch methods may the pilot conduct as PIC today? ^q31 - A) Winch and bungee. - B) Winch, bungee and aero-tow. - C) Winch and aero-tow. - D) Aero-tow and bungee. **Correct: A)** > **Explanation:** Under Part-SFCL (SFCL.010 and SFCL.160), a pilot must have completed at least 5 launches using a specific launch method within the preceding 24 months to act as PIC using that method. The pilot has 9 winch (qualifies) and 2 bungee launches (qualifies, threshold is met), but only 4 aero-tow launches — which is below the required 5. Therefore, aero-tow is not permitted without additional training or a check flight with an instructor. ### Q32: Which of the following documents have to be on board for an international flight? a) Certificate of aircraft registration b) Certificate of airworthiness c) Airworthiness review certificate d) EASA Form-1 e) Airplane logbook f) Appropriate papers for every crew member g) Technical logbook ^q32 - A) B, c, d, e, f, g - B) A, b, c, e, f - C) D, f, g - D) A, b, e, g **Correct: A)** > **Explanation:** Per ICAO Annex 6 and EU Regulation 965/2012, international flights require: Certificate of Airworthiness (b), Airworthiness Review Certificate (c), EASA Form-1 or equivalent release document (d), the aircraft logbook/journey log (e), licences and medical certificates for each crew member (f), and the technical/maintenance logbook (g). The Certificate of Registration (a) is technically required too under ICAO Annex 7, but the answer set B, c, d, e, f, g (option A) represents the standard EASA enumeration tested in this question context. ### Q33: What is the minimum flight visibility in airspace "C" for an aircraft operating under VFR at FL110? ^q33 - A) 1500 m - B) 3000 m - C) 8000 m - D) 5000 m **Correct: C)** > **Explanation:** Per SERA.5001, at and above FL100, the minimum flight visibility for VFR flight in all controlled airspace classes (including class C) is 8000 m (8 km). This higher minimum is required at high altitudes because aircraft speeds are typically greater, reducing reaction time, and the increased altitude makes maintaining visual separation from IFR traffic more critical. FL110 is above FL100, so the 8000 m minimum applies. ### Q34: During a flight at FL 80, the altimeter setting has to be... ^q34 - A) Local QFE. - B) Local QNH. - C) 1030.25 hPa. - D) 1013.25 hPa. **Correct: D)** > **Explanation:** Flight levels (FL) are defined relative to the standard atmosphere pressure of 1013.25 hPa (the International Standard Atmosphere setting, also called QNE or standard setting). When flying at or above the transition altitude (which varies by country but is typically between 3000 ft and 18,000 ft), pilots set their altimeter to 1013.25 hPa and read flight levels. QNH gives altitude above sea level, QFE gives height above a specific aerodrome — neither is used when referencing flight levels. ### Q35: What is the purpose of the semi-circular rule? ^q35 - A) To fly without a filed flight plan in prescribed zones published in the AIP - B) To avoid collisions by suspending turning manoeuvres - C) To avoid collisions by reducing the probability of opposing traffic at the same altitude - D) To allow safe climbing or descending in a holding pattern **Correct: C)** > **Explanation:** The semi-circular (hemispherical) cruising level rule (SERA.5015) assigns specific altitude bands to specific magnetic tracks — eastbound flights use odd thousands of feet, westbound flights use even thousands. By separating aircraft flying in opposite directions onto different altitude levels, the probability of a head-on collision at the same altitude is greatly reduced. This is a passive separation tool requiring no ATC involvement, applicable primarily to en-route cruise flight above the transition altitude. ### Q36: Which transponder code should be set during a radio failure without any request? ^q36 - A) 7700 - B) 7600 - C) 7500 - D) 7000 **Correct: B)** > **Explanation:** Upon experiencing a radio communication failure, the pilot should immediately squawk 7600 (the international radio failure code) without waiting for any ATC request or instruction — since communication is by definition impossible. Code 7700 is for general emergencies, 7500 for unlawful interference, and 7000 is the general VFR code. Setting 7600 proactively informs ATC of the situation, triggering the loss-of-communications procedures defined in national AIPs and ICAO Annex 11. ### Q37: Which transponder code has to be set unrequested during an emergency? ^q37 - A) 7500 - B) 7700 - C) 7000 - D) 7600 **Correct: B)** > **Explanation:** In any general emergency (engine failure, fire, medical emergency, severe structural damage, etc.), the pilot must set transponder code 7700 immediately and without waiting for ATC instruction. Code 7700 triggers an alarm on ATC radar displays and activates emergency procedures. Code 7500 is specifically for unlawful interference (hijacking) only — it should not be used for other emergencies. The phrase "unrequested" emphasises that the pilot must act autonomously without waiting for radio contact. ### Q38: Which air traffic service is responsible for the safe conduct of flights? ^q38 - A) ATC (air traffic control) - B) AIS (aeronautical information service) - C) ALR (alerting service) - D) FIS (flight information service) **Correct: A)** > **Explanation:** Air Traffic Control (ATC) is specifically responsible for providing separation between aircraft and ensuring the safe, orderly, and expeditious flow of air traffic, including the safe conduct of flights in controlled airspace. FIS provides information useful for safe and efficient conduct of flights but does not control aircraft. ALR initiates search and rescue when aircraft are overdue or in distress. AIS provides aeronautical information publications but has no operational control role. Per ICAO Annex 11, ATC has the active separation and safety function. ### Q39: Which air traffic services can be expected within an FIR (flight information region)? ^q39 - A) FIS (flight information service) ALR (alerting service) - B) ATC (air traffic control) FIS (flight information service) - C) ATC (air traffic control) AIS (aeronautical information service) - D) AIS (aeronautical information service) SAR (search and rescue) **Correct: A)** > **Explanation:** A Flight Information Region (FIR) is the basic organisational unit of airspace, within which two services are provided: FIS (Flight Information Service) — providing pilots with weather, NOTAM, and other relevant information — and ALR (Alerting Service) — notifying appropriate organisations when aircraft are in distress or overdue. ATC is only provided within designated controlled airspace (CTAs, CTRs, airways) that may exist within an FIR, not throughout the entire FIR. Per ICAO Annex 11, FIS and ALR are the universal FIR services. ### Q40: Which of the following options states a correct position report? ^q40 - A) DEABC reaching "N" - B) DEABC, "N", 2500 ft - C) DEABC over "N" in FL 2500 ft - D) DEABC over "N" at 35 **Correct: B)** > **Explanation:** A standard position report per ICAO Doc 4444 includes: aircraft callsign, position (fix or waypoint), and altitude/flight level. Option B (DEABC, "N", 2500 ft) provides all three elements concisely and correctly. Option A is incomplete (no altitude). Option C uses nonsensical terminology ("FL 2500 ft" — flight levels and feet are not combined this way). Option D lacks altitude and uses "at 35" without context. Correct position reporting is essential for ATC situational awareness. ### Q41: The shown NOTAM is valid until... A1024/13 A) LOWW B) 1305211200 C) 1305211400 E) STOCKERAU VOR STO 113.00 UNSERVICEABLE. ^q41 - A) 13/10/2013 00:00 UTC. - B) 21/05/2014 13:00 UTC. - C) 21/05/2013 14:00 UTC. - D) 13/05/2013 12:00 UTC. **Correct: C)** > **Explanation:** NOTAM time codes use the format YYMMDDHHMM in UTC. The "C)" field in a NOTAM is the end time (the "until" time). The code 1305211400 is decoded as: Year 13 (2013), Month 05 (May), Day 21, Time 1400 UTC — giving 21 May 2013 at 14:00 UTC. The "B)" field (1305211200) is the start time: 21 May 2013 at 12:00 UTC. The NOTAM number A1024/13 confirms it is from 2013. Correct NOTAM decoding is a fundamental Air Law skill. ### Q42: The term "aerodrome elevation" is defined as... ^q42 - A) The highest point of the apron. - B) The lowest point of the landing area. - C) The highest point of the landing area. - D) The average value of the height of the manoeuvring area. **Correct: C)** > **Explanation:** Per ICAO Annex 14, aerodrome elevation is defined as the elevation of the highest point of the landing area. This definition ensures that the published elevation represents the most demanding terrain height that aircraft must clear during approach and departure from the landing surface. It is not the average, not the apron elevation, and not the lowest point. Aerodrome elevation is used to calculate QFE (the altimeter setting that causes the altimeter to read zero at the aerodrome) and for obstacle clearance calculations. ### Q43: Of what shape is a landing direction indicator? ^q43 - A) T - B) A straight arrow - C) L - D) An angled arrow **Correct: A)** > **Explanation:** Per ICAO Annex 14, the landing direction indicator is T-shaped (commonly called a "landing T" or "signal T"). When displayed, the cross-bar of the T indicates the direction in which landings and take-offs should be made — aircraft land toward and take off away from the cross-bar. The T is white and should be clearly visible from the air. The L-shaped indicator is used for a different purpose (indicating a right-hand traffic circuit). Arrows are not the standard ICAO shape for a landing direction indicator. ### Q44: What is indicated by a pattern of longitudinal stripes of uniform dimensions disposed symmetrically about the centerline of a runway? ^q44 - A) At this point the glide path of an ILS hits the runway - B) Do not touch down before them - C) Do not touch down behind them - D) A ground roll could be started from this position **Correct: B)** > **Explanation:** Longitudinal stripes arranged symmetrically about the runway centreline are the runway threshold markings (specifically the threshold stripe pattern), which indicate the beginning of the runway available for landing. Pilots must not touch down before them. They do not mark an ILS glide path touchdown point (A), do not prohibit touching down behind them (C), and are not a ground roll starting position marker (D). ### Q45: Which validity does the "Certificate of Airworthiness" have? ^q45 - A) Unlimited - B) 12 years - C) 6 months - D) 12 months **Correct: A)** > **Explanation:** The Certificate of Airworthiness (CofA) itself has unlimited validity — once issued, it remains valid as long as the aircraft continues to meet its type design standards and is properly maintained. What is periodically renewed (typically annually) is the Airworthiness Review Certificate (ARC), which confirms that the aircraft's continuing airworthiness has been verified. The confusion between CofA and ARC is a common exam trap. ### Q46: A pilot license issued in accordance with ICAO Annex 1 is valid in... ^q46 - A) Those countries that have accepted this license on application. - B) The country where the license was acquired. - C) All ICAO countries. - D) The country where the license was issued. **Correct: C)** > **Explanation:** ICAO Annex 1 (Personnel Licensing) establishes international standards for pilot licences. A licence issued in full compliance with Annex 1 standards is recognised and valid in all 193 ICAO Contracting States without requiring individual acceptance. This mutual recognition is a cornerstone of international civil aviation — it allows pilots to operate across borders seamlessly. Options B and D are the same concept (country of issue) and are too restrictive; option A incorrectly implies case-by-case acceptance is required. ### Q47: What is the subject of ICAO Annex 1? ^q47 - A) Flight crew licensing - B) Air traffic services - C) Rules of the air - D) Operation of aircraft **Correct: A)** > **Explanation:** ICAO Annex 1 covers Personnel Licensing, which includes standards for flight crew licences (PPL, CPL, ATPL), ratings, medical certificates, and instructor qualifications. Annex 2 covers Rules of the Air, Annex 11 covers Air Traffic Services, and Annex 6 covers Operation of Aircraft. Knowing the ICAO Annexes by number and subject is a standard Air Law exam requirement. ### Q48: What is the minimum flight visibility in airspace "C" for an aircraft operating under VFR at FL125? ^q48 - A) 8000 m - B) 1500 m - C) 5000 m - D) 3000 m **Correct: A)** > **Explanation:** FL125 is above FL100, so the SERA.5001 rule for high-altitude VFR applies: minimum flight visibility is 8000 m in all controlled airspace classes including class C. This is the same threshold as Q22 — both FL110 and FL125 are above FL100, so both require 8000 m. The 5000 m minimum applies below FL100 in most controlled airspace, and the 3000 m/1500 m minima apply only in lower uncontrolled airspace. ### Q49: What are the minimum distances to clouds for a VFR flight in airspace "B"? ^q49 - A) Horizontally 1.500 m, vertically 300 m - B) Horizontally 1.500 m, vertically 1.000 m - C) Horizontally 1.000 m, vertically 300 m - D) Horizontally 1.000 m, vertically 1.500 ft **Correct: A)** > **Explanation:** In airspace class B (and also A), VFR flights are generally not permitted unless specifically authorised. However, where VFR is permitted in class B, the cloud clearance minima per SERA.5001 are 1500 m horizontal and 300 m (approximately 1000 ft) vertical. Note that option A states "300 m" vertically using the metre equivalent, while option B states "1000 m" vertically — the correct vertical minimum is 300 m (not 1000 m). The "1000 ft" vertical minimum translates to approximately 300 m. ### Q50: Being intercepted by a military aircraft at daytime, what is the meaning of the following signal: A sudden heading change of 90 degrees or more and a pull-up of the aircraft without crossing the track of the intercepted aircraft? ^q50 - A) Follow me, i will bring you to the next suitable airfield - B) You may continue your flight - C) Prepare for a safety landing, you have entered a prohibited area - D) You are entering a restricted area, leave the airspace immediately **Correct: B)** > **Explanation:** Per ICAO Annex 2, Appendix 1, Section 2, when an intercepting aircraft makes an abrupt break-away manoeuvre of 90 degrees or more and climbs away without crossing the intercepted aircraft's track, this signal means "You may proceed" — the intercept is complete and the intercepted aircraft is cleared to continue its flight. This is the standard release signal. The "follow me" signal involves the interceptor rocking wings and heading towards a destination. Pilots must study all ICAO interception signals as part of Air Law. ### Q51: Which answer is correct with regard to separation in airspace "E"? ^q51 - A) VFR traffic is not separated from any other traffic - B) VFR traffic is separated only from IFR traffic - C) VFR traffic is separated from VFR and IFR traffic - D) IFR traffic is separated only from VFR traffic **Correct: A)** > **Explanation:** In class E airspace, IFR traffic receives separation from other IFR traffic, but VFR traffic is not separated from anything — neither from other VFR traffic nor from IFR traffic. VFR flights in class E receive traffic information where possible (from FIS) but no ATC separation service. This is a key distinction for glider pilots who frequently operate in class E: they must maintain their own separation from all traffic using see-and-avoid principles. Class E is the lowest class of controlled airspace where IFR is permitted. ### Q52: A Pre-Flight Information Bulletin (PIB) is a presentation of current... ^q52 - A) AIC information of operational significance prepared after the flight. - B) AIP information of operational significance prepared prior to flight. - C) NOTAM information of operational significance prepared prior to flight. - D) ICAO information of operational significance prepared after the flight. **Correct: C)** > **Explanation:** A PIB (Pre-Flight Information Bulletin) is a standardised summary of current NOTAMs relevant to a planned flight, prepared and issued prior to departure. It filters and presents the NOTAMs pertinent to the route, departure and destination aerodromes, and alternate aerodromes. It is based on NOTAM data (not AIP or AIC data), and is prepared before the flight (not after). PIBs are available from AIS offices, online briefing systems, and flight planning services. Per ICAO Annex 15, it is a key pre-flight planning tool. ### Q53: How can a wind direction indicator be marked for better visibility? ^q53 - A) The wind direction indicator may be mounted on top of the control tower. - B) The wind direction indicator could be made from green materials. - C) The wind direction indicator could be surrounded by a white circle. - D) The wind direction indicator could be located on a big black surface. **Correct: C)** > **Explanation:** Per ICAO Annex 14, a wind direction indicator (windsock or wind tee) should be clearly visible and may be surrounded by a white circle to enhance its visibility against the aerodrome background. This white circle provides a high-contrast surround that makes the indicator easier to identify from the air. Mounting it on the control tower (option A) is not a standard visibility-enhancement method. Green materials (B) do not aid visibility. A black surface (D) is not specified as a standard method in ICAO Annex 14. ### Q54: Which distances to clouds have to be maintained during a VFR flight in airpaces C, D and E? ^q54 - A) 1500 m horizontally, 1000 ft vertically - B) 1000 m horizontally, 1500 ft vertically - C) 1000 m horizontally, 300 m vertically - D) 1500 m horizontally, 1000 m vertically **Correct: A)** > **Explanation:** Per SERA.5001, in airspace classes C, D, and E, VFR flights must maintain a horizontal separation of 1500 m from cloud and a vertical separation of 1000 ft (approximately 300 m) from cloud. The key distinction to remember is that the horizontal minimum is in metres (1500 m) and the vertical minimum is in feet (1000 ft) — mixing units is a common error. These minima apply above 3000 ft AMSL or above 1000 ft AGL, whichever is higher. ### Q55: How can a pilot confirm a search and rescue signal on ground in flight? ^q55 - A) Push the rudder in both directions multiple times - B) Fly in a parabolic flight path multiple times - C) Rock the wings - D) Deploy and retract the landing flaps multiple times **Correct: C)** > **Explanation:** ICAO Annex 12 prescribes that a pilot in flight confirms acknowledgement of a ground SAR signal by rocking the wings (waggling the wings laterally). This is an internationally recognised visual signal. Rudder inputs (A) are not visible from the ground, a parabolic flight path (B) is not a defined SAR signal, and repeated flap deployment (D) is not a standard acknowledgement signal. ### Q56: What is the meaning of the abbreviation "SERA"? ^q56 - A) Selective Radar Altimeter - B) Standardized European Rules of the Air - C) Standard European Routes of the Air - D) Specialized Radar Approach **Correct: B)** > **Explanation:** SERA stands for Standardised European Rules of the Air, established by Commission Implementing Regulation (EU) No 923/2012. SERA harmonises the rules of the air across all EU member states, implementing ICAO Annex 2 provisions at European level and adding EU-specific rules. It covers right-of-way rules, VMC minima, altimeter settings, signals, and related procedures. The other options are invented abbreviations not used in aviation. ### Q57: A flight is called a "visual flight", if the... ^q57 - A) Visibility in flight is more than 5 km. - B) Flight is conducted under visual flight rules. - C) Visibility in flight is more than 8 km. - D) Flight is conducted in visual meteorological conditions. **Correct: B)** > **Explanation:** A "visual flight" (VFR flight) is defined by the rules under which it is conducted — specifically, Visual Flight Rules (VFR) — not simply by the prevailing visibility. A flight is VFR when the pilot navigates by external visual reference and complies with VFR separation minima and procedures. VMC (Visual Meteorological Conditions) describes the weather minima required to conduct VFR flight; but a flight can be in VMC and still be flown under IFR. The distinction between the rule set and the conditions is important. ### Q58: Air traffic control service is conducted by which services? ^q58 - A) ALR (alerting service) SAR (search and rescue service) TWR (aerodrome control service) - B) FIS (flight information service) AIS (aeronautical information service) AFS (aeronautical fixed telecommunication service) - C) APP (approach control service) ACC (area control service) FIS (flight information service) - D) TWR (aerodrome control service) APP (approach control service) ACC (area control service) **Correct: D)** > **Explanation:** Per ICAO Annex 11, the three constituent units of Air Traffic Control service are: TWR (Aerodrome Control — controls traffic at and around the aerodrome), APP (Approach Control — handles departing and arriving traffic in the terminal area), and ACC (Area Control Centre — handles en-route traffic in control areas/airways). FIS is a separate service from ATC. ALR and SAR are emergency services, not ATC. AIS and AFS are information/communication services, not control services. ### Q59: An aerodrome beacon (ABN) is a... ^q59 - A) Fixed beacon installed at an airport or aerodrome to indicate its location to aircraft pilots from the air - B) Rotating beacon installed at the beginning of the final approach to indicate its location to aircraft pilots from the air. - C) Rotating beacon installed at an airport or aerodrome to indicate its location to aircraft pilots from the air. - D) Rotating beacon installed at an airport or aerodrome to indicate its location to aircraft pilots from the ground. **Correct: C)** > **Explanation:** An aerodrome beacon (ABN) is defined by ICAO as a ROTATING beacon (not fixed) installed at or near an airport to help pilots locate it from the air. It is located at the aerodrome itself, not at the beginning of final approach (B). It is intended to be seen from the air by pilots, not from the ground (D). Option A is wrong because the beacon rotates. ### Q60: What is the primary purpose of an aircraft accident investigation? ^q60 - A) To identify the reasons and work out safety recommendations - B) To clarify questions of liability within the meaning of compensation for passengers - C) To work for the public prosecutor and help to follow-up flight accidents - D) To Determine the guilty party and draw legal consequences **Correct: A)** > **Explanation:** ICAO Annex 13 and EU Regulation 996/2010 are explicit: the sole objective of an aircraft accident investigation is to prevent future accidents and incidents by identifying causal factors and issuing safety recommendations. It is not a judicial or liability process. Determining liability (B), assisting prosecutors (C), or establishing guilt (D) is explicitly outside the scope of a safety investigation. ### Q61: The term "runway" is defined as a... ^q61 - A) Round area on an aerodrome prepared for the landing and take-off of aircraft - B) Rectangular area on a land aerodrome prepared for the landing and take-off of helicopters. - C) Rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. - D) Rectangular area on a land or water aerodrome prepared for the landing and take-off of aircraft. **Correct: C)** > **Explanation:** Per ICAO Annex 14, a runway is defined as a rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. The key elements are: rectangular (not round), land aerodrome (not water — water aerodromes have alighting areas, not runways), and aircraft in general (not specifically helicopters, which use helidecks or helipads). Option D is incorrect because runways are specific to land aerodromes. Option A is wrong (shape). Option B is wrong (specifies helicopters only). ### Q62: A pilot can contact FIS (flight information service)... ^q62 - A) By a personal visit. - B) Via telephone. - C) Via radio communication. - D) Via internet. **Correct: C)** > **Explanation:** FIS (Flight Information Service) is an operational ATC service provided to airborne pilots in flight. The primary and essentially only operational means of contacting FIS during flight is via radio communication on the designated FIS frequency. While pre-flight briefing information may be obtained by telephone or online, the in-flight FIS service itself is radio-based. A personal visit is meaningless for an airborne pilot, and internet communication is not used for real-time in-flight FIS contact. ### Q63: What is the meaning of the abbreviation "VMC"? ^q63 - A) Variable meteorological conditions - B) Visual meteorological conditions - C) Instrument flight conditions - D) Visual flight rules **Correct: B)** > **Explanation:** VMC stands for Visual Meteorological Conditions — the specific weather minima of visibility and cloud clearance defined in SERA.5001 that must be met for VFR flight to be conducted. If conditions fall below VMC minima, the airspace is said to be in IMC (Instrument Meteorological Conditions) and VFR flight is not permitted unless special VFR clearance is granted. VMC minima vary by airspace class and altitude band. ### Q64: What information is provided in the part "AD" of the AIP? ^q64 - A) Warnings for aviation, ATS airspaces and routes, restricted and dangerous airspaces. - B) Access restrictions for airfields, passenger controls, requirements for pilots, license samples and validity periods - C) Table of content, classification of airfields with corresponding maps, approach charts, taxi charts - D) Map icons, list of radio nav aids, time for sunrise and sunset, airport fees, air traffic control fees **Correct: C)** > **Explanation:** The AD (Aerodromes) section of the AIP contains all aerodrome-specific information: aerodrome classification, runway data, lighting, frequencies, ground handling, approach and departure charts, taxi charts, obstacle data, operating hours, and special procedures. Option A describes ENR content. Option D describes GEN content. Option B contains a mix of items that do not correspond to a single AIP section. The AD section is what a pilot consults to prepare for operations at a specific aerodrome. ### Q65: Which validity does the Certificate of Airworthiness have? ^q65 - A) Unlimited - B) 12 years - C) 6 months - D) 12 months **Correct: A)** > **Explanation:** A Certificate of Airworthiness (CofA) issued under ICAO Annex 8 and EASA regulations remains valid for an unlimited period as long as the aircraft is maintained in accordance with approved maintenance programmes and the Airworthiness Review Certificate (ARC) is kept current. The CofA itself has no fixed expiry date; it is the ARC (reviewed annually) that must be renewed periodically. ### Q66: What is the meaning of the abbreviation ARC? ^q66 - A) Airworthiness Recurring Control - B) Airspace Rulemaking Committee - C) Airworthiness Review Certificate - D) Airspace Restriction Criteria **Correct: C)** > **Explanation:** ARC stands for Airworthiness Review Certificate, the document issued following a successful airworthiness review confirming that an aircraft meets the applicable airworthiness requirements at the time of review. It is valid for one year and must be renewed to allow continued operation. The other options (Airworthiness Recurring Control, Airspace Rulemaking Committee, Airspace Restriction Criteria) are not recognised EASA or ICAO abbreviations in this context. ### Q67: The Certificate of Airworthiness is issued by the state... ^q67 - A) Of the residence of the owner - B) In which the aircraft is registered. - C) In which the airworthiness review is done. - D) In which the aircraft is constructed. **Correct: B)** > **Explanation:** Under the Chicago Convention (ICAO Annex 7) and EASA regulations, the Certificate of Airworthiness is issued by the State of Registry — the country in which the aircraft is registered. The nationality of the owner (A), the country where the review was conducted (C), or the country of manufacture (D) are not the determining factors for issuing the CofA. ### Q68: What is the meaning of the abbreviation SERA? ^q68 - A) Selective Radar Altimeter - B) Standardized European Rules of the Air - C) Standard European Routes of the Air - D) Specialized Radar Approach **Correct: B)** > **Explanation:** SERA stands for Standardised European Rules of the Air, the EU regulation (Commission Implementing Regulation (EU) No 923/2012) that harmonises rules of the air across EASA member states. It is not an acronym for a radar device (A), a routing document (C), or a radar approach (D). ### Q69: What is the meaning of the abbreviation TRA? ^q69 - A) Transponder Area - B) Temporary Reserved Airspace - C) Terminal Area - D) Temporary Radar Routing Area **Correct: B)** > **Explanation:** TRA stands for Temporary Reserved Airspace, an airspace of defined dimensions temporarily reserved for specific uses (such as military exercises or parachute operations) and which other aircraft may not enter without permission. Transponder Area (A), Terminal Area (C), and Temporary Radar Routing Area (D) are not standard ICAO or EASA designations for this abbreviation. ### Q70: What is the meaning of an area marked as TMZ? ^q70 - A) Transponder Mandatory Zone - B) Transportation Management Zone - C) Touring Motorglider Zone - D) Traffic Management Zone **Correct: A)** > **Explanation:** TMZ stands for Transponder Mandatory Zone, an airspace designation indicating that aircraft must be equipped with and operate a functioning transponder when flying in that zone. Transportation Management Zone (B), Touring Motorglider Zone (C), and Traffic Management Zone (D) are not recognised aviation terms for this abbreviation. ### Q71: A flight is called a visual flight, if the... ^q71 - A) Visibility in flight is more than 5 km. - B) Flight is conducted under visual flight rules. - C) Visibility in flight is more than 8 km. - D) Flight is conducted in visual meteorological conditions. **Correct: B)** > **Explanation:** A visual flight (VFR flight) is defined as a flight conducted in accordance with Visual Flight Rules, as specified in ICAO Annex 2 and SERA. The definition is regulatory, not purely meteorological. Stating specific visibility values such as 5 km (A) or 8 km (C) conflates VFR with VMC minima but does not define the term. Option D (flight in VMC) describes a condition under which VFR is possible, not the definition of a VFR flight itself. ### Q72: What is the meaning of the abbreviation VMC? ^q72 - A) Variable meteorological conditions - B) Visual meteorological conditions - C) Instrument flight conditions - D) Visual flight rules **Correct: B)** > **Explanation:** VMC stands for Visual Meteorological Conditions, the meteorological visibility and cloud clearance conditions under which VFR flight can be conducted. It is not 'variable' conditions (A), instrument flight conditions (C), or Visual Flight Rules (D) — VFR is the set of rules followed in VMC, not the conditions themselves. ### Q73: What is the minimum flight visibility in airspace E for an aircraft operating under VFR at FL75? ^q73 - A) 8000 m - B) 1500 m - C) 3000 m - D) 5000 m **Correct: D)** > **Explanation:** In ICAO airspace classification, airspace E is uncontrolled above Class G. VFR flights in Class E below FL100 require a minimum flight visibility of 5,000 m (5 km). FL75 is below FL100 so the 5 km rule applies. 8,000 m (A) applies at and above FL100, 1,500 m (B) is the minimum in some lower airspaces under certain conditions, and 3,000 m (C) does not correspond to any standard VFR minimum in this context. ### Q74: What is the minimum flight visibility in airspace C for an aircraft operating under VFR at FL110? ^q74 - A) 1500 m - B) 3000 m - C) 8000 m - D) 5000 m **Correct: C)** > **Explanation:** In controlled airspace Class C at and above FL100, the minimum VFR flight visibility is 8,000 m (8 km) in accordance with SERA. FL110 is above FL100, so the 8 km minimum applies. 1,500 m (A) and 3,000 m (B) are minima for lower airspaces. 5,000 m (D) applies below FL100. ### Q75: What is the minimum flight visibility in airspace C for an aircraft operating under VFR at FL125? ^q75 - A) 8000 m - B) 1500 m - C) 5000 m - D) 3000 m **Correct: A)** > **Explanation:** In airspace Class C at and above FL100, the minimum VFR flight visibility is 8,000 m. FL125 is above FL100, confirming the 8 km (8,000 m) minimum applies. The answer 5,000 m (C) applies below FL100 in Class C. 1,500 m (B) and 3,000 m (D) correspond to other airspace or altitude bands. ### Q76: What are the minimum distances to clouds for a VFR flight in airspace B? ^q76 - A) Horizontally 1.500 m, vertically 300 m - B) Horizontally 1.500 m, vertically 1.000 m - C) Horizontally 1.000 m, vertically 300 m - D) Horizontally 1.000 m, vertically 1.500 ft **Correct: A)** > **Explanation:** In ICAO airspace Class B (and Classes C and D), the cloud separation minima for VFR flights are 1,500 m horizontally and 300 m (1,000 ft) vertically from cloud. Option B uses 1,000 m vertical separation which is too large. Option C uses 1,000 m horizontal which is insufficient. Option D mixes metres and feet incorrectly. ### Q77: What is the minimum flight visibility in airspace C below FL 100 for an aircraft operating under VFR? ^q77 - A) 1.5 km - B) 8 km - C) 5 km - D) 10 km **Correct: C)** > **Explanation:** In airspace Class C below FL100, the SERA-prescribed minimum VFR flight visibility is 5 km (5,000 m). 1.5 km (A) is for special VFR or certain lower-altitude situations. 8 km (B) applies at and above FL100 in Class C. 10 km (D) is not a standard SERA minimum. ### Q78: What is the minimum flight visibility in airspace C at and above FL 100 for an aircraft operating under VFR? ^q78 - A) 1.5 km - B) 10 km - C) 5 km - D) 8 km **Correct: D)** > **Explanation:** In airspace Class C at and above FL100, the minimum VFR flight visibility required by SERA is 8 km (8,000 m). Below FL100 in Class C the minimum is 5 km. 1.5 km (A) applies to special VFR scenarios. 5 km (C) is the below-FL100 Class C minimum. 10 km (B) is not a standard SERA VFR minimum. ### Q79: The term ceiling is defined as the... ^q79 - A) Height of the base of the highest layer of clouds covering more than half of the sky below 20000 ft. - B) Height of the base of the lowest layer of clouds covering more than half of the sky below 10000 ft. - C) Height of the base of the lowest layer of clouds covering more than half of the sky below 20000 ft. - D) Altitude of the base of the lowest layer of clouds covering more than half of the sky below 20000 ft. **Correct: C)** > **Explanation:** The ICAO definition of ceiling is the height (not altitude) of the base of the lowest layer of clouds or obscuring phenomena covering more than half the sky (BKN or OVC, i.e., more than 4 oktas), below 20,000 ft. Option A uses 'highest layer' which is incorrect. Option B limits it to below 10,000 ft which is too restrictive. Option D uses 'altitude' (referenced to MSL) rather than 'height' (referenced to the surface), which is technically incorrect per ICAO definition. ### Q80: Which answer is correct with regard to separation in airspace E? ^q80 - A) VFR traffic is not separated from any other traffic - B) VFR traffic is separated only from IFR traffic - C) VFR traffic is separated from VFR and IFR traffic - D) IFR traffic is separated only from VFR traffic **Correct: A)** > **Explanation:** In airspace Class E, ATC provides separation only for IFR flights. VFR flights in Class E receive no separation service from ATC — they are not separated from IFR traffic or from other VFR traffic. Pilots operating VFR in Class E rely on the see-and-avoid principle. Options B, C, and D incorrectly imply some form of ATC-provided separation for VFR flights. ### Q81: What information is provided in the part AD of the AIP? ^q81 - A) Warnings for aviation, ATS airspaces and routes, restricted and dangerous airspaces. - B) Access restrictions for airfields, passenger controls, requirements for pilots, license samples and validity periods - C) Table of content, classification of airfields with corresponding maps, approach charts, taxi charts - D) Map icons, list of radio nav aids, time for sunrise and sunset, airport fees, air traffic control fees **Correct: C)** > **Explanation:** The AIP is divided into three main parts: GEN (General), ENR (En Route), and AD (Aerodromes). The AD part contains information about individual aerodromes including their classification, aerodrome charts, approach charts, and taxi charts. Warnings, airspace, and restrictions (A) are in ENR. License and regulatory info (B) is in GEN. Map icons and radio nav aids (D) are also primarily in GEN or ENR. ### Q82: The term aerodrome elevation is defined as... ^q82 - A) The highest point of the apron. - B) The lowest point of the landing area. - C) The highest point of the landing area. - D) The average value of the height of the manoeuvring area. **Correct: C)** > **Explanation:** Aerodrome elevation is defined by ICAO as the elevation of the highest point of the landing area. This is the point referenced for QFE settings and various aerodrome obstacle clearance calculations. The apron (A) is not the landing area. The lowest point (B) would understate the elevation relevant to operations. An average value (D) does not reflect the critical highest-point definition. ### Q83: The term runway is defined as a... ^q83 - A) Round area on an aerodrome prepared for the landing and take-off of aircraft - B) Rectangular area on a land aerodrome prepared for the landing and take-off of helicopters. - C) Rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. - D) Rectangular area on a land or water aerodrome prepared for the landing and take-off of aircraft. **Correct: C)** > **Explanation:** ICAO Annex 14 defines a runway as a rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. It is specifically rectangular (not round), on land (not water — that would apply to seaplanes on water aerodromes), and for aircraft generally (not helicopters specifically — helicopter landing areas are called HELIPADs or FATO). ### Q84: What is the meaning of DETRESFA? ^q84 - A) Distress phase - B) Alerting phase - C) Uncertainty phase - D) Rescue phase **Correct: A)** > **Explanation:** DETRESFA is the ICAO codeword for the distress phase, which is the highest of the three emergency phases and indicates that an aircraft is believed to be in grave and imminent danger requiring immediate assistance. ALERFA (alerting phase) and INCERFA (uncertainty phase) are the other two phases. 'Rescue phase' (D) is not a defined ICAO emergency phase designation.
