Question 1

What type of fuel system design prevents fuel from being trapped unusable in a tank during unusual attitudes?

Accepted Answer

Collector cell or surge box design

Answer

Collector cells or surge boxes ensure a constant supply of fuel to the engine even during prolonged unusual attitudes or low fuel states.

Question 2

Which brake system is designed to prevent wheel lockup and skidding during heavy braking?

Accepted Answer

Anti-skid (autobrake anti-skid) system

Answer

Anti-skid systems modulate hydraulic brake pressure to prevent wheel lockup, maintaining directional control and minimizing stopping distance.

Question 3

What is the purpose of a fuel crossfeed valve on a multi-engine aircraft?

Accepted Answer

Transfer fuel between tanks to maintain balance or supply all engines from one tank

Answer

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.

Question 4

What is the significance of a 'go-around' thrust setting on a modern airliner?

Accepted Answer

A pre-programmed thrust level for missed approach with engine inoperative protection

Answer

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.

Question 5

On large transport aircraft, what is the primary structural component that transfers wing lift loads to the fuselage?

Accepted Answer

Wing spar carry-through structure

Answer

The wing spar carry-through structure connects the wing spars through the fuselage, transferring bending and shear loads from the wings to the airframe.
