What takes up the shock of the landing impact in an oleo shock strut? |
The metered transfer of oil from one compartment to another inside the shock strut |
|
|
What takes up the taxi shock in an oleo shock strut? |
Compressed air |
|
|
What is the purpose of the centering cam in the nose wheel shock strut? |
It forces the nose-wheel to stay straight before it is retracted into the nose-wheel well. |
|
|
How does a shimmy damper keep a nose-wheel from shimmying? |
It acts like a small hydraulic shock absorber between the piston and the cylinder of the nose-wheel shock strut |
|
|
what is the purpose of a deboster in a hydraulic power break system? |
It decreases the pressure and increases the volume of fluid going into the brakes giving the pilot a better control of the brakes |
|
|
What should be done to hydraulic brakes when the pedal has a spongy feel? |
Bleed the brake system of the air trapped in the system |
|
|
What is used in a split wheel to keep air from leaking between the two wheel halves? |
An o-ring seal |
|
|
What causes an aircraft tire to wear more on the shoulders than in the center of the tread? |
operating the tire while its under inflated |
|
|
What causes an aircraft tire to wear more on the center of the tread than on the shoulders? |
Operating the tires in an over inflated condition |
|
|
What should be done to the aircraft tire if the side walls are weather checked enough to expose the cord? |
It is cause for rejection of the tire |
|
|
Why is it important that some aircraft with retractable landing gear be given a retraction test after a new retreaded tire is installed? |
It's possible that the new retreaded tire has a different size that would prevent the gear from retracting and could lock up the system |
|
|
How is the correct amount of air in an oleo shock strut determined? |
By the amount it extends from the cylinder when the aircraft weight is on it. |
|
|
What should be done with a tire that was on a wheel which was overheated enough to melt the fusible plug in the wheel? |
The tire should be scrapped |
|
|
Where can you find the correct inflation pressure for the tires on an aircraft? |
On the aircraft service manual |
|
|
What is the purpose of the compensator port in the master cylinder of aircraft brakes? |
It prevents pressure from building up in the brake lines and causing the brake to drag by opening up the brake reservoir to the wheel cylinder when the brakes are off |
|
|
What is the purpose of the shuttle valve in the brake system of an aircraft using hydraulic power brakes? |
Allows the System to use the automatic transfer valves which operates with hydraulic system pressure under normal conditions, and if that is lost, it allows the brake system to operate under the emergency backup system |
|
|
How does an anti-skid system keeps the wheels of an aircraft from skiding on a wet runway |
By monitoring rate of deceleration of the wheels. If any wheel slows down faster than it should it would begin to skid and the pressure on the brake and the wheel is released until it starts decelerating and the pressure is reapplied |
