Correct: C)
Explanation: A sudden loss of cable tension during the steep climb phase of a winch launch must be treated as a cable break. The glider is at a high nose-up attitude with rapidly decreasing airspeed, making an imminent stall the greatest danger. The pilot must push the stick firmly forward to lower the nose and regain flying speed, then release the cable immediately. Option A (aileron signals) wastes critical time in a life-threatening situation. Option B (pulling the elevator) would pitch the nose even higher, guaranteeing a stall. Option D (waiting) risks a full stall before any recovery is possible.
Correct: B)
Explanation: A second cable lying close to the glider before launch is a serious entanglement hazard. If the cable wraps around the glider or its own launch cable during the take-off run, it could cause catastrophic loss of control, structural damage, or prevent the pilot from releasing the cable. The only safe action is to abort the launch immediately by releasing the cable and informing the controller so the hazard can be cleared. Option A delays action until after take-off, when entanglement may already have occurred. Options C and D both proceed with the launch despite the known hazard, which is unacceptable.
Correct: B)
Explanation: The weak link is a fusible element in the winch cable system designed to break at a predetermined load before the glider's airframe structural limits are exceeded. If cable tension becomes dangerously high -- due to excessive winch power, a sudden wind gust, or the pilot pitching up too steeply -- the weak link fails first, protecting the glider from structural damage. Option A is incorrect because climb rate is controlled by the winch operator and pilot, not the weak link. Option C is wrong because the cable is normally released by the pilot at the top of the launch. Option D describes protecting the winch, but the weak link is calibrated to the glider's structural limits.
Correct: C)
Explanation: Maintaining strong back pressure on the elevator at the moment the cable releases -- whether by the pilot or the automatic back-release -- causes a violent pitch-up as the restraining force of the cable suddenly disappears while the elevator is still commanding nose-up. This creates extreme structural loads (high positive g-forces) on the airframe, potentially exceeding design limits and causing structural failure. The correct technique is to progressively ease back pressure as the launch nears its peak. Option A misunderstands the release mechanism. Option B confuses wind correction with pitch control. Option D wrongly encourages a dangerous practice.
Correct: B)
Explanation: Landing on a steeply inclined slope requires extra approach speed to provide adequate control authority and safety margin in the turbulent and unpredictable conditions typical of mountainous terrain. A quick, decisive flare is needed to match the glider's flight path to the slope gradient at the moment of touchdown, preventing the nose from striking the uphill surface. Option A (minimum speed) leaves no margin for wind shear or turbulence common near slopes. Option C (parallel approach) does not address the need to land uphill. Option D (approaching downhill) means landing with a tailwind component and increasing groundspeed, making the landing extremely dangerous.
Correct: C)
Explanation: At 6000 m, the time of useful consciousness without supplemental oxygen is only a few minutes. The pilot must begin an immediate emergency descent using full spoilers and the maximum permissible speed to reach breathable altitude (below approximately 3000 m) as quickly as possible. Option A is dangerously wrong -- remaining at 6000 m without oxygen for 30 minutes would result in unconsciousness and death. Option B (slow breathing) does not meaningfully extend oxygen duration at this altitude. Option D (waiting for symptoms) is too late -- hypoxia impairs judgment first, and the pilot may not recognise their own deterioration.
Correct: C)
Explanation: Emergency controls in aircraft are universally colour-coded red to ensure instant recognition under stress, in poor lighting, or when the pilot is disoriented after an accident. The emergency canopy jettison handle must be immediately identifiable because rapid egress may be needed following a crash or fire. This red colour coding is an international aviation standard applied consistently across all aircraft types. Options A (blue), B (yellow), and D (green) are used for other cockpit functions but never for emergency release mechanisms.
Correct: B)
Explanation: Ballast and trim masses in a glider must be rigidly secured because any movement during flight can have catastrophic consequences. A loose weight sliding aft shifts the centre of gravity beyond the approved limit, potentially making the aircraft uncontrollable in pitch. If a weight slides into the control linkage area, it could physically jam the rudder, elevator, or aileron cables, preventing the pilot from controlling the aircraft. Option A (maximum mass) is a separate loading consideration, not about securing. Option C (comfort) is trivial compared to the safety issue. Option D (injury protection) is a secondary concern to the primary risk of loss of control.
Correct: B)
Explanation: If the ASI fails during a winch launch that is otherwise proceeding normally, the pilot can continue to normal launch altitude using the horizon for pitch reference and airstream noise as an approximate speed indicator. After release, the pilot should fly an immediate circuit and land, using the same visual and auditory cues. Option A (immediate release and short circuit) may be overly hasty if the launch is stable. Option C is unsafe -- continuing a cross-country flight without a functioning ASI means flying without reliable speed information, which is dangerous particularly in varying conditions. Option D (abrupt speed changes) could destabilise the launch and is not a troubleshooting method.
Correct: D)
Explanation: With the centre of gravity at or beyond the aft limit, the moment arm between the CG and the elevator is shortened, reducing the elevator's ability to generate a corrective pitching moment. In extreme cases, the pilot may be unable to push the nose down to prevent a stall or recover from a pitch-up, particularly during the critical phases of winch launch or aerotow. This makes the aircraft effectively uncontrollable in pitch. Option A (speed reduction) is not the primary concern. Option B (nose-down moment) is backwards -- an aft CG creates a nose-up tendency, not nose-down. Option C (structural limits) relates to loading, not CG position.
Correct: D)
Explanation: Ice accumulation on the wings disrupts the smooth aerofoil shape, increasing surface roughness and altering the lift distribution. This reduces the maximum lift coefficient the wing can produce, meaning the wing must fly faster to generate sufficient lift, which raises the stall speed. Ice also adds weight and significantly increases drag, further degrading performance. For gliders, even a thin layer of ice can cause dramatic performance loss. Option A is incorrect -- ice increases surface roughness and drag. Option B is wrong because slow-flight performance worsens severely. Option C is the opposite of what happens.
Correct: C)
Explanation: An unlocked undercarriage poses the risk of collapsing unpredictably on touchdown, which can cause the glider to veer violently, ground-loop, or nose-over. A controlled belly landing with gear fully retracted at minimum speed provides a predictable, stable deceleration on the fuselage skid. Minimum speed reduces the impact forces and sliding distance. Option A (increased speed) unnecessarily increases the impact energy. Option B (landing on unlocked gear) risks uncontrolled collapse. Option D (holding the handle) provides no guarantee the gear will stay extended under landing loads and distracts the pilot during a critical phase.
Correct: C)
Explanation: Heavy snowfall can reduce visibility from adequate VMC to near-zero almost instantaneously, which is the most immediately dangerous effect for a VFR glider pilot. Without visual references, the pilot cannot maintain spatial orientation, see terrain, obstacles, or other aircraft, and is at immediate risk of controlled flight into terrain or disorientation. Option A (icing) is a concern but develops more gradually. Option B (pitot blockage) affects speed indication but is less immediately life-threatening than total loss of visual reference. Option D (increased mass) is a minor secondary effect.
Correct: D)
Explanation: In a tailwind landing, the pilot maintains normal indicated airspeed (the stall margin must be preserved regardless of wind direction), but the groundspeed will be higher than normal, resulting in a longer flare distance and significantly longer ground roll. The pilot must select a field long enough to accommodate this. Option A (increased speed, no spoilers) worsens the situation by adding even more groundspeed. Option B (late spoiler deployment) does not allow proper glidepath management. Option C (reduced speed) dangerously reduces the margin above stall and is incorrect -- a tailwind increases, not decreases, the ground roll distance.
Correct: C)
Explanation: With a tailwind, the approach should be flown at normal indicated airspeed, but the approach angle relative to the ground will appear shallower because the higher groundspeed means the glider covers more ground per unit of altitude lost. The pilot must recognise this flatter trajectory and plan for the longer ground roll. Option A (retracting gear) removes braking capability and is dangerous. Option B (increasing speed) adds even more groundspeed and worsens the landing distance problem. Option D (sideslip) does not effectively compensate for a tailwind -- it increases drag and sink rate but does not reduce groundspeed.
Correct: D)
Explanation: In gusty conditions (10 kt gust spread between 15 and 25 kt), the pilot should add a gust correction factor to the normal approach speed -- typically half the gust increment (5 kt in this case) -- to maintain an adequate margin above stall when a gust temporarily drops away and airspeed decreases. Firm, positive control inputs are needed to promptly correct the rapid attitude changes caused by gusts. Option A avoids spoilers, which are essential for glidepath control. Option B uses normal speed, leaving insufficient margin for gust-induced speed loss. Option C (minimum speed) is dangerous because any gust dropout could cause an immediate stall.
Correct: A)
Explanation: Strong sink while ridge soaring indicates the pilot has entered the lee-side downdraft zone where descending air can exceed the glider's maximum sink rate, trapping it in a downward flow near terrain. The immediate response is to increase speed to best penetration speed and head away from the ridge toward the valley or upwind side, where conditions are safer and landing options exist. Option B is dangerously complacent -- mountain downdrafts can be sustained and powerful. Option C (closer to the ridge) increases terrain collision risk. Option D (landing parallel to the ridge) may not be feasible on steep terrain.
Correct: D)
Explanation: A cumulus developing into a cumulonimbus produces extreme updrafts that can suck a glider into the cloud involuntarily, where severe turbulence, icing, lightning, and loss of visual orientation create life-threatening conditions. The pilot must immediately open spoilers and accelerate to maximum permissible speed (VNE) to maximise descent rate and escape the lifting area as quickly as possible. Option A (slowing down) reduces the ability to escape and increases the risk of being drawn into the cloud. Option B (continuing to thermal) invites disaster. Option C (entering the cloud) is potentially fatal in a glider without full instrument capability.
Correct: D)
Explanation: Any loose object in a glider cockpit is a potential flight safety hazard because it can slide into the control linkage area and jam the rudder pedals, control column, or trim mechanism, preventing the pilot from controlling the aircraft. A pen lodged under a rudder pedal can prevent full deflection at a critical moment. Before the next flight, the cockpit must be thoroughly searched and the object found and removed. Option A (informing others) is insufficient -- the object must be found. Option B is irrelevant to flight safety. Option C is dangerously wrong -- even small items can jam critical controls.
Correct: D)
Explanation: When trying to reach the airfield through strong sink at low altitude, the pilot should fly at best glide speed (which maximises distance per unit of altitude lost) plus additional speed to compensate for the sinking air and any headwind. The speed increment accounts for the fact that the sink reduces the effective glide ratio, and additional speed improves penetration through the descending air mass. Option A (VA) is higher than necessary and wastes altitude. Option B (best glide speed alone) does not account for the adverse conditions. Option C (minimum sink speed) maximises time aloft but minimises ground coverage, which is the wrong priority when trying to reach a specific point.
Correct: B)
Explanation: Under EASA regulation FCL.135.S, a newly issued LAPL(S) holder must complete at least 10 hours of flight time or 30 flights as pilot-in-command on sailplanes after licence issue before carrying passengers. This consolidation requirement ensures the pilot gains sufficient solo experience before taking responsibility for another person's safety. Option A is incorrect because recent experience alone is not sufficient -- the post-licence minimum must also be met. Option C is wrong because the restriction clearly exists. Option D is incorrect because the LAPL(S) does permit passenger carrying after the experience requirement is fulfilled.
Correct: B)
Explanation: On final approach to an out-landing field, the pilot is committed to landing and should not attempt to exploit a thermal at low altitude. A strong thermal will lift the glider above the intended approach path, potentially causing an overshoot. The correct response is to fully extend the airbrakes to increase sink rate and maintain control of the approach, extending the approach path if necessary to arrive at the correct height over the threshold. Option A (retracting airbrakes and thermalling) is extremely dangerous at low altitude. Option C is incorrect because approach management must be active. Option D (circling on final) wastes altitude and risks losing the field.
Correct: D)
Explanation: A wet grass surface significantly reduces the friction between the glider's wheel and the ground, making braking less effective and extending the ground roll distance. The pilot must anticipate this reduced braking performance and ensure the available runway length is sufficient. Using the wheel brake aggressively on wet grass can also cause the wheel to lock and the glider to skid. Option A (aquaplaning) is more of a concern on hard paved surfaces at high speed than on grass. Options B and C are the opposite of reality -- wet grass decreases, not increases, braking effectiveness.
Correct: C)
Explanation: Late in the day, when sunlit and shaded areas alternate across a valley, the contrast makes it extremely difficult to detect other aircraft against the dark background of shaded slopes. Aircraft that would be clearly visible against a sunlit hillside become nearly invisible in shadow, significantly increasing the risk of mid-air collision. This visual detection challenge demands heightened vigilance and predictable flight paths in valley flying. Option A (severe turbulence) and Option B (strong downdrafts) are not specifically linked to shading. Option D (sun glare) is a different visibility issue unrelated to shaded slopes.
Correct: B)
Explanation: The field selection must be finalised no later than 300 m AGL for a pure glider, leaving sufficient altitude to fly a proper circuit pattern and approach. For a motor glider, the decision altitude is 400 m AGL because the pilot needs additional height to manage engine start procedures and has the added complexity of the power unit. Below these altitudes, the pilot should be committed to the chosen field and flying the circuit. Option A does not specify a concrete altitude. Option C reverses the values. Option D sets the motor glider limit too low at 200 m AGL.
Correct: B)
Explanation: When thermalling alone with no other gliders in the thermal, there is no regulation or convention dictating which direction to circle. The pilot is free to choose whichever direction best centres the thermal or feels most comfortable. The rule to conform to a set direction applies only when another aircraft is already established in the thermal -- in that case, the newcomer must adopt the direction of the first aircraft. Option A imposes an unnecessary restriction. Option C cites a nonexistent proximity rule. Option D (figure eights) is not an efficient thermalling technique.
Correct: C)
Explanation: After a towrope break below safety height in calm conditions, the pilot should first establish a stable gliding attitude to maintain safe airspeed, then release the remaining cable by pulling the release twice (to ensure complete separation). With insufficient altitude for a turn in calm conditions, the pilot should land straight ahead if possible, using the available field ahead. Option A deploys airbrakes immediately, which may be premature before assessing the situation. Option B attempts a 180-degree turn below safety height, which is extremely dangerous without wind assistance. Option D releases only once, which may not ensure complete cable separation.
Correct: C)
Explanation: With a strong crosswind from the right, the upwind (right) wing tends to be lifted by the wind, which could cause the glider to roll left and dig the left wingtip into the ground. By having the ground helper hold the right wing slightly lower at the start of the ground roll, this tendency is counteracted until the glider reaches sufficient speed for the ailerons to become effective. Option A refers to engine power, which is irrelevant for a glider. Option B (pulling back fully) risks a premature, uncontrolled lift-off in the crosswind. Option D (running alongside) is impractical beyond the first few metres and does not address the specific wing-lifting problem.
Correct: B)
Explanation: If the tug-and-glider combination is not accelerating adequately and the pre-determined abort point is reached without sufficient speed, the only correct action is to release the towrope immediately. Continuing a take-off with insufficient speed risks an uncontrolled stall shortly after lift-off or running off the end of the runway. Option A (reducing drag) will not solve a fundamental acceleration problem. Option C (pulling to get airborne) forces the glider into the air below safe flying speed, risking an immediate stall. Option D (extending flaps) may increase lift but does not address the root cause of insufficient acceleration.
Correct: B)
Explanation: Regulations for ridge soaring specify a minimum lateral clearance of 60 metres from the slope. This safety margin provides reaction time if the pilot encounters sudden sink, turbulence, or a wind shift near the terrain, and prevents collision with the slope surface. Option A is too vague and does not specify a concrete value. Option C (150 m) overstates the regulatory minimum, though greater clearance is always prudent in adverse conditions. Option D incorrectly suggests the clearance is variable based on thermal activity rather than being a fixed minimum requirement.
