outflow valve open completely

air cycle machine will stop.

negative pressure relief valve will close.

The heat for the anti-icing system of a turbofan engine intake is provided by:

a dedicated generator on the gearbox of that engine.

bleed air from the HP compressor

bleed air from the LP compressor.

Shuttle valves will automatically…

shut down systems that are overloaded.

reduce pump loads.

switch hydraulically operated units to the most appropriate pressure supply.

guard systems against overpressure

In transport aircraft equipped with retractable landing gear, there must be a clear indication to the pilot ..

whenever the landing gear position is not consistent with landing gear selector lever position.

whenever the landing gear selector is not in the neutral position.

when gear selection is performed above the gear limit speed.

whenever the gear is erroneously selected to retract on the ground.

The hydraulic device, which functionality is comparable to a diode in an electrical circuit, is a:

flow control valve.

shutoff valve

distribution valve

check valve.

A single acting actuator:

is powered in one direction only by hydraulic power, the return movement being under another force.

application of hydraulic power.

ravels one direction under one application of hydraulic power and in the opposite direction under a second

is a one shot actuator used for emergency systems only.

cannot be used for variable position operations as it is designed to lock in the extremities of travel.

The auto-brake system stops operating during landing ..

by the pilot extending ground spoilers.

by the pilot selecting idle reverse thrust.

when the pilot does not lower the nose wheel to the ground.

by pilot action.

A flight control surface actuator is said to be "irreversible" when:

the pilot does not feel any force when moving that control surface in flight.

there is a need to lock the flight controls on the ground.

there is no feedback to the pilot's controls of the aerodynamic forces acting on the control surface.

the flight control system has an alternate means of control in case of a control jam.

The purposes of an accumulator in a hydraulic system are to..

cool the hydraulic fluid and serve as a main pressure source for normal operation.

cool the hydraulic fluid and serve as a limited alternate source of pressure.

damp pressure fluctuations and serve as a limited alternate source of pressure.

damp pressure fluctuations and serve as a main pressure source for normal operation.

Due to a mechanical failure, the flaps are only extended in one of the wings. What will happen?

The aircraft will roll and yaw to the side where the flaps are extended.

The aircraft will roll and yaw to the side where the flaps are not extended.

The aircraft will roll to the side where the flaps are not extended and yaw to the direction of the wing with extended flaps.

The aircraft will roll to the side where the flaps are extended and yaw to the same direction

of the roll.
