Landing Gear Systems Flashcards
What is used to inflate a landing gear shock strut?
Dry air or nitrogen
What is the purpose of main landing gear torque links?
They keep the landing gear pointed in a straight ahead direction
What power sources are normally used to retract landing gear systems?
Hydraulic or electric
What unit prevents nosewheel vibration?
A shimmy damper
What type of nosewheel steering is provided on small aircraft?
A simple system consisting of mechanical linkage hooked to the rudder pedal
What are some types of brake actuating systems?
independent, booster, and power control
What is the purpose of power brake debooster cylinders?
Reduce the pressure to the brakes and increase the volume of fluid flow
What must be accomplished before inspecting a wheel brake system for hydraulic leaks?
Pressurize the system
What prevents a split wheel from leaking air through the inner and outer mating surfaces, or the wheel assembly?
A rubber packing between the two assemblies
What is the most necessary maintenance function for safe, long, aircraft tire service?
Proper inflation
What are the effects of under inflation on tires?
Rapid or uneven wear near the edge of the tread, and creep or slip when the brakes are applied
When should a landing gear retraction check be accomplished?
During an annual inspection, when landing gear components have been replaced, and after hard landings
What is the purpose of the anti-skid system?
To bring a fast moving aircraft to a stop during ground roll without tire skidding
What is the indication of excessive heating of a wheel bearing?
Discoloration ; Bluish tint to the metal surface
What is the purpose of a wheel fusible plug?
Melts at a certain temperature to relieve air pressure to prevent tire blowout
