landing gear1
Landing Gear
  • What are three advantages of a tricycle landing gear over a tail-wheel type landing gear?
landing gear2
Landing Gear
  • It allows more forceful application of the brakes without the danger of nosing the aircraft over
  • It permits better visibility for the pilot during ground operations
landing gear3
Landing Gear
  • It prevents the tendency for the aircraft to ground loop.
landing gear4
Landing Gear
  • What is the name of the landing gear that has more than two wheels mounted on a single strut?
  • A bogie landing gear
landing gear5
Landing Gear
  • What is the function of the drag strut in a retractable landing gear?
landing gear6
Landing Gear
  • The drag strut braces the landing gear against fore-and-aft movement of the wheel, and it hinges in its middle to allow the landing gear to be retracted into the aircraft structure.
landing gear7
Landing Gear
  • What are the two most commonly used methods of actuating a retractable landing gear?
  • Electric Motor
  • Hydraulic Cylinder
landing gear8
Landing Gear
  • Gear Position Indicators
    • Red light
    • One or three green lights
    • Press to test
landing gear9
Landing Gear
  • What are four methods of emergency extension of a retractable landing gear?
landing gear10
Landing Gear
  • Hand crank
  • Designed so it will free fall and lock down mechanically
  • Hydraulic pressure can be built up by a hand pump
landing gear11
Landing Gear
  • Actuated with compressed air from a storage cylinder
landing gear12
Landing Gear
  • Maximum landing gear extended speed VLE
  • Maximum landing gear operating speed VLO
landing gear13
Landing Gear
  • What is the commonly used name for the landing gear safety switch that is located on the torque links?
  • A squat switch
landing gear14
Landing Gear
  • Explain when you would retract the gear after takeoff?
landing gear15
Landing Gear
  • Explain when you would retract the gear after takeoff?
  • Two positive rates of climb and once there is no more runway available for landing in front of the airplane
landing gear16
Landing Gear
  • What is the function of the warning horn in a retractable landing gear system?
landing gear17
Landing Gear
  • The horn sounds to warn the pilot that the throttles are closed to the position for landing of the aircraft if the landing gear is not down and locked. It is different from the stall warning horn.
landing gear18
Landing Gear
  • How is nosewheel steering accomplished on a light aircraft?
landing gear19
Landing Gear
  • Most light aircraft have some form of direct linkage between the nose-wheel and the rudder pedals that allow the nose-wheel to be steered when the aircraft is on the ground.
landing gear20
Landing Gear
  • How is nose-wheel steering accomplished on a heavy aircraft?
landing gear21
Landing Gear
  • The nose-wheels of most heavy aircraft are steered with hydraulic actuators that are controlled by moving a small wheel that is turned by the pilot.
landing gear22
Landing Gear
  • What is the function of the shimmy damper that is used on a tricycle landing gear?
landing gear23
Landing Gear
  • The shimmy damper restrains the movement of the nose-wheel. It allows the wheel to be steered by moving it slowly, but does not allow the wheel to move back and forth rapidly.
landing gear24
Landing Gear
  • Why do modern high-performance aircraft use several small wheels rather than fewer large wheels on their landing gear?
landing gear25
Landing Gear
  • Small wheels spread the weight of the aircraft over a larger area
  • Several smaller wheels give a margin of safety in case one tire should fail
landing gear26
Landing Gear
  • Small wheels and tires are easier to house in the aircraft structure than large ones
landing gear27
Landing Gear
  • What is indicated by a tire wearing on the shoulder of the tread more that in the center of the tread?
landing gear28
Landing Gear
  • What is indicated by a tire wearing on the shoulder of the tread more that in the center of the tread?
  • The tire has been operated under-inflated
landing gear29
Landing Gear
  • How soon after landing should aircraft tires be checked for proper inflation?
landing gear30
Landing Gear
  • No sooner that two hours after the aircraft has landed. The correct inflation pressure in a tire is the pressure when the tire is cold.
landing gear31
Landing Gear
  • Why is it important that the tread of a tire not be allowed to wear to the point that water cannot pass under the tire?
landing gear32
Landing Gear
  • If water cannot pass under the tire, the airplane is likely to hydroplane or skid on wet runways?
landing gear33
Landing Gear
  • What is one of the main dangers of operating a tubeless tire in an underinflated condition?
landing gear34
Landing Gear
  • When the tire is operated in an underinflated condition, the cords flex and generate enough heat to damage the tire.
