Question 1

A scissor is a component found on landing gears. Its function is to:

Accepted Answer

Prevent any rotation of the oleo strut in the undercarriage shock absorber.

Answer

Make the body gears pivot when the nose wheel is turned through more than 20°.

Answer

Transform the translational movement of the rudder pedals into the rotational movement of the nose wheel.

Answer

Create The Wheel Pitch On Bogie Gears.

Question 2

Pneumatic mechanical devices that provide ice protection:

Accepted Answer

Are usually used as de-icing devices.

Answer

Are usually used on aeroplanes equipped with turbo-fan engines.

Answer

Require large quantities of bleed air.

Answer

Can Only Be Used As Anti-icing Devices.

Question 3

On a modern aeroplane, to avoid the risk of tyre burst from overheating, due for example to prolonged braking during an aborted take-off, there is:

Accepted Answer

A hollow bolt screwed into the wheel which melts at a given temperature (thermal fuse) and deflates the tyre.

Answer

A Pressure Relief Valve Situated In The Filler Valve.

Answer

Water injection triggered at a fixed temperature in order to lower tyre temperature.

Answer

The 'emergency Burst' Function Of The Anti-skid System Which Adapts Braking To The Tyre Temperature.

Question 4

VLO is the maximum:

Accepted Answer

Speed at which the landing gear can be operated with full safety.

Answer

Cruising speed not to be exceeded except in still air with caution.

Answer

Speed with flaps extended in a given position.

Answer

Flight Speed With Landing Gear Down.

Answer

Ensure The Input Signal Is Ac Only.

Answer

Ensure the input signal is DC only.

Answer

Ensure the output signal is of the same state as the input signal.
