1) A breaker strip in an aircraft tyre is Report

to provide strength

to provide a wear indication

to indicate the position for tyre levers

2) If fluid leaks along with air whilst oleo charging, this is Report

caused by a leaky seal

normal

due to excessive charging pressure

3) A red dot / triangle mark on aircraft tyres means Report

military reference

the light part of the tyre

breather points

4) On selection of MLG down, the gear extends then begins to retract again. The cause is Report

a faulty selector valve

a faulty actuator

gear lowered at too high an airspeed

5) When fitting a tyre, the red dot should be positioned Report

on the other side of the wheel opposite to the charging valve

opposite the charging valve

adjacent to the charging valve

6) Composite brake units Report

weigh the same as normal brake units and fade away athigh temperatures

have less weight than normal brake units but fade away at high temperatures

have less weight than normal brake units and have increased efficiency at high temperatures

7) A restrictor valve can be used Report

to increase the speed of undercarriage retraction

to increase the speed of the undercarriage extension

to reduce the speed of the undercarriage extension

8) When an undercarriage is lowered, it tends to creep back up. The fault could be Report

the emergency system

a leaky selector valve

a stuck relief valve

9) Vents holes are found on Report

tubeless tyres

tubed tyres

tubed and tubeless tyres

10) At what temperature does a yellow fuse plug melt at? Report

150⁰C

200⁰C

250⁰C

11) The cam plate in a nose undercarriage is Report

part of the shimmy damper

to align for nose wheel on nose undercarriage retraction

for alignment of the nose wheel steering on nose undercarriage extension

12) What is tyre creep related to? Report

Horizontal movement of the tyre

Vertical movement of the tyre

Tyre moving around the wheel

13) 'Aquaplaning' can be reduced by Report

increased flaring

lowering slats

an anti-skid device

14) Why is a hydraulic damper fitted to a nose wheel steering system?. Report

To reduce vibration and shimmy

To centralise the nose wheel during an up selection

To centralise the nose leg assembly during an up selection

15) What decides the type of oil used in an undercarriage leg? Report

The material of the leg

The types of seals the leg uses

Neither, any oil can be used

16) In an anti-skid system Report

brakes release on rising torque

brakes release on falling torque

brakes are modulated to give most efficient braking

17) If an undercarriage oleo has insufficient deflection, the likely cause is Report

oil level too high

loss of pressure/leakage

air pressure too high

18) A Maxaret is used in what system? Report

Tyre inflation

Skid control

Self centring landing gear

19) The pilot receives an audible warning on the flight deck as the aircraft is descending to land. The most likely reason for this warning is Report

the airspeed is too high

the rate of descent is too high

the landing gear is not locked down

20) A restrictor in the landing gear hydraulic retraction and lowering system is positioned in the Report

landing gear up line

landing gear down line

return line from the landing gear selector
