Which propulsion concept, prototyped for short-haul regional aircraft, uses many small battery- or generator-driven electric fans distributed along the wing to improve aerodynamic and propulsive efficiency?
- A. Hybrid turbofan burning a bio-fuel blend
- B. Distributed electric propulsion (DEP)
- C. Hydrogen fuel-cell turboprop
- D. Open-rotor (unducted fan) engine
What is the primary technical advantage of a blended-wing-body (BWB) aircraft over a conventional tube-and-wing design?
- A. Higher maximum take-off weight for a given engine thrust
- B. A higher lift-to-drag ratio and lower structural weight per unit of payload
- C. A simpler cabin pressurisation system
- D. Easier integration of winglets
In next-generation air traffic management, what does the term "free flight" specifically refer to?
- A. Pilots navigating without any ATC clearance at all
- B. Aircraft selecting their own optimal 4-D trajectories within defined separation and airspace constraints
- C. Unmanned aerial vehicles operating in civilian airspace
- D. The removal of all ground-based radar
Which material combination is most actively explored for morphing wing skins that change camber in flight, reducing reliance on conventional hinged flaps?
- A. Carbon-fibre reinforced polymer skins with embedded shape-memory alloy actuators
- B. Aluminium-lithium alloy panels driven by hydraulic pistons
- C. Titanium sheet with external electro-mechanical jackscrews
- D. Magnesium alloy panels with sliding mechanical linkages
What is the key benefit of satellite-based ADS-B over traditional radar for oceanic and remote routes?
- A. It removes the need for aircraft to carry transponders
- B. It provides continuous surveillance coverage where ground radar cannot reach
- C. It reduces aircraft fuel burn by a guaranteed 15%
- D. It allows aircraft to fly above their certified ceiling
Which emerging cabin technology aims to reduce motion sickness by resolving the mismatch between what passengers see and what they feel?
- A. Augmented-reality headrests
- B. Dynamic circadian LED lighting cycles
- C. Virtual-window displays showing an exterior view matched to aircraft motion
- D. Personalised climate-control vents
In eVTOL air-taxi design, what distinguishes a "lift-plus-cruise" configuration?
- A. Its rotors tilt from vertical to horizontal for forward flight
- B. It uses dedicated vertical-lift rotors plus a separate propeller for forward thrust
- C. It uses one large main rotor and a tail rotor, like a helicopter
- D. Its fans are buried in the fuselage and vector thrust through nozzles
How does quantum key distribution (QKD) improve the security of communication links?
- A. It encrypts data with algorithms that are mathematically unbreakable
- B. It encodes key material in quantum states, so any eavesdropping disturbs them and is detected
- C. It stores encryption keys in a blockchain aboard the aircraft
- D. It converts all payload data into qubits that cannot be intercepted
What is the main aerodynamic challenge in designing a variable-geometry inlet for a supersonic passenger jet?
- A. Maintaining cabin pressurisation at Mach 2
- B. Keeping the shock system positioned correctly to avoid inlet unstart across a wide speed range
- C. Keeping engine dry weight below 5 tonnes
- D. Fitting wing-tip fuel tanks without a drag penalty
Which biometric approach is furthest advanced in trials to replace boarding passes and manual ID checks with a contactless passenger flow?
- A. Facial recognition matched against a digital travel credential held by the passenger
- B. Iris scanning combined with RFID wristbands
- C. Voiceprint authentication via the aircraft intercom
- D. Palm-vein scanning stored on an airline app
