Aircraft Landing Gear Systems Flashcards
What is the purpose of main landing gear torque links?
They keep the landing gear pointed in a straight direction.
What is used to inflate landing gear shock strut?
Dry air or Nitrogen.
What power sources are normally used to retract landing gear systems?
Hydraulic or Electrical motors.
What prevents a nose landing gear from being retracted with the nosewheel out of the center position?
Nosewheel centering cams or external track.
When should a landing gear retraction check be accomplished?
Annual inspection, Replacements, Hard Landings or other programed inspecions.
What methods are used for transmitting cockpit control movements to a steering control unit in large aircraft?
Mechanical, Electrical or Hydraulic.
What type of nosewheel steering is provided on small aircraft?
A simple system consisting of mechanical linkage hooked to the rudder pedals.
What unit prevents nosewheel vibration?
A shimmy damper.
What prevents a Split Wheel from leaking air through the inner and outher mating surfaces, or the wheel assembly?
An O ring between the halves.
What is the indication of excessive heating of a wheel bearing?
Discoloration
What is the purpose of a wheel fusible plug?
To relieve air pressure to prevent tire blowout.
What are some types of brake actuating systems?
Independent master cylinders, boosted brakes and power control-controlled brakes.
What is the purpose of power brake debooster?
Reduces hydraulic system hight pressure to a lower value for more satisfatory brakes action.
What is the purpose of an anti-skid system?
It prevents the wheels to skid or lock during brakes attempts.
What are some methods of bleeding brakes?
Gravity and pressure methods.
