What type of fuel system design prevents fuel from being trapped unusable in a tank during unusual attitudes?
Answer: Collector cell or surge box design
Collector cells or surge boxes ensure a constant supply of fuel to the engine even during prolonged unusual attitudes or low fuel states.
Which brake system is designed to prevent wheel lockup and skidding during heavy braking?
Answer: Anti-skid (autobrake anti-skid) system
Anti-skid systems modulate hydraulic brake pressure to prevent wheel lockup, maintaining directional control and minimizing stopping distance.
What is the purpose of a fuel crossfeed valve on a multi-engine aircraft?
Answer: Transfer fuel between tanks to maintain balance or supply all engines from one tank
Crossfeed valves allow any engine to draw fuel from any tank, useful for fuel balance management or feeding all engines from one tank during an emergency.
What is the significance of a 'go-around' thrust setting on a modern airliner?
Answer: A pre-programmed thrust level for missed approach with engine inoperative protection
Go-around thrust is a selectable power setting that commands maximum approved thrust for the missed approach, including protection for all-engine and engine-out scenarios.
On large transport aircraft, what is the primary structural component that transfers wing lift loads to the fuselage?
Answer: Wing spar carry-through structure
The wing spar carry-through structure connects the wing spars through the fuselage, transferring bending and shear loads from the wings to the airframe.
What system automatically adjusts control surface deflection to maintain aircraft stability without pilot input?
Answer: Stability augmentation system (SAS)
Stability augmentation systems make small, rapid control surface corrections to improve aircraft handling qualities, particularly in yaw and pitch axes.
Which component in a turbofan engine is responsible for compressing air before it enters the combustion chamber?
Answer: Compressor
The compressor section—composed of multiple axial stages—increases air pressure before it is mixed with fuel and ignited in the combustion chamber.
