LANDING GEAR SYSTEMS
What takes up the shocks 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 shocks in an oleo shock strut?
The compressed air or nitrogen.
How much oil should be put into an oleo shock strut?
Deflate the strut completely, remove the filler plug and fill the strut with oil to the level of the
filler plug.
What is the purpose of the centering cam in a nosewheel shock strut?
The centering cams forces the nosewheel straight back with the strut before it is retracted into
the nosewheel well.
How does a shimmy damper keep a nosewheel from shimmying?
It acts as a small hydraulic shock absorber between the piston and the cylinder of the
nosewheel shock strut.
What is the purpose of the debooster in a hydraulic power brake system?
The debooster decreases the pressure and increases the volume of fluid going to the brakes.
This gives the pilot be,er control of the brakes.
What should be done to hydraulic brakes when the pedal has a spongy feel?
The spongy feel is caused by air in the brake. The brakes should be bled of this air.
What is used in a split wheel to keep air from leaking between the two well halves?
An O-ring seal.
What causes an aircra/ 0re to wear more on the shoulders than in the center of the thread?
Opera0ng the 0re in an under inflated condi0on.
What causes an aircra/ 0re to wear more on the center of the thread than on the shoulders?
, Opera0ng the 0re in an overinflated condi0on.
What should be done to an aircra/ 0re if the sidewalls are weather checked enough to expose
the chord?
The 0re should be scrapped.
Why is it important that some aircra/ with retractable landing gear be given a retrac0on test
a/er new or retreated 0res are installed?
It is possible in some aircra/ that a new or retreated 0re can be different enough in size from
the previous 0re that it could lock up in the wheel well when the landing gear is retracted.
How is the correct amount of air in an oleo shock strut determined?
By the amount the strut extends out of the cylinder when the weight of the aircra/ is on it.
What should be done with a 0re that was on a wheel which was overheated enough to melt the
fusible plug in the wheel?
The 0re should be scrapped.
Where can you find the correct infla0on pressure for the 0res of an aircra/?
In the aircra/ service manual.
What is the purpose of the compensator port in the master cylinder of aircra/ brakes?
The compensator port in the master cylinder opens the brake reservoir to the wheel cylinders
when the brakes are off. This prevent pressure from building up in the brake lines and causing
the brakes to drag.
What is the purpose of the shu,le valve in the brake system of an aircra/ using hydraulic power
brakes?
The shu,le valve is an automa0c transfer valve. It allows the brakes to be operated by hydraulic
system pressure under all normal condi0ons, but if this pressure is lost, it allows the brakes to
be operated by the emergency back up system.
How does an an0skid brake system keep the wheels of an aircra/ from skidding on a wet
runway?
The an0skid system monitors the rate of decelera0on of the wheels. If any wheel slows down
faster than it should (as it would at the beginning of the skid), the pressure on the brake in that
wheel is released un0l the wheel stop decelera0ng, then the pressure is reapplied.
