  • Chapter 12: Transition to Complex Airplanes › Retractable Landing Gear › Landing Gear Systems

    Landing Gear Systems An electrical landing gear retraction system utilizes an electrically-driven motor for gear operation. The system is basically an electrically-driven jack for raising and lowering the gear. When a switch in the flight deck is moved ... continues to operate until an up or down limit switch on the motor’s gearbox is tripped. A hydraulic landing gear retraction system utilizes pressurized hydraulic fluid to actuate linkages to raise and lower the gear. When a switch…

  • Chapter 2: Ground Operations › Preflight Assessment of the Aircraft › Landing Gear, Tires, and Brakes

    Landing Gear, Tires, and Brakes The landing gear, tires, and brakes allow the airplane to maneuver from and return to the ramp, taxiway, and runway environment in a precise and controlled manner. The landing gear, tires, and brakes should ... inspected to ensure that the airplane can be positively controlled on the ground. Landing gear on airplanes varies from simple fixed gear to complex retractable gear systems. Fixed landing gear is a gear system in which the landing gear struts…

    compressed gas, which is directed to uplock release cylinders. In some airplanes, design configurations make emergency extension of the landing gear by gravity and air loads alone impossible or impractical. In these airplanes, provisions are included for forceful gear extension ... such as a hand crank for emergency gear extension. [Figure 12-14] Hydraulic pressure for emergency operation of the landing gear may be provided by an auxiliary hand pump, an accumulator, or an electrically-powered hydraulic pump depending…

  • Chapter 7: Aircraft Systems › Hydraulic Systems › Fixed and Retractable Landing Gear

    Fixed and Retractable Landing Gear Landing gear can also be classified as either fixed or retractable. Fixed landing gear always remains extended and has the advantage of simplicity combined with low maintenance. Retractable landing gear is designed to streamline ... airplane by allowing the landing gear to be stowed inside the structure during cruising flight. [Figure 7-39] Brakes Airplane brakes are located on the main wheels and are applied by either a hand control or by foot pedals…

    aircraft must be serviced with the type specified by the manufacturer. Refer to the AFM/POH or the Maintenance Manual. Landing Gear The landing gear forms the principal support of an aircraft on the surface. The most common type of landing ... also be equipped with floats for water operations or skis for landing on snow. [Figure 7-37] The landing gear on small aircraft consists of three wheels: two main wheels (one located on each side of the fuselage…

    Pushing the handle fully downward closes the outlet valve and allows any nitrogen present in the emergency landing gear extension system to be vented overboard. The venting process takes approximately 30 seconds. Dump Valve As compressed nitrogen is released ... landing gear selector/dump valve during emergency extension, the pneudraulic pressure actuates the dump valve portion of the landing gear selector/dump valve to isolate the landing gear system from the remainder of hydraulic system. When activated, a blue DUMP legend…
