  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 ... gear consists of wheels, but aircraft can 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…

  control or aircraft in the pattern. To avoid this, the instructor should only use concise prompting on approach to landings with the learner. Certain landings present unique risks. The instructor teaches the appropriate pre-landing reconnaissance for unfamiliar landing areas ... uncontrolled fields. During landings in strong winds, the instructor should have the skill sufficient to deal with the wind conditions. During a short-field or confined area landing, certain aircraft may fly at a slower approach speed. The instructor should…

  Chapter 7: Aircraft Systems › Hydraulic Systems › Tailwheel Landing Gear

  Tailwheel Landing Gear Tailwheel landing gear airplanes have two main wheels attached to the airframe ahead of its CG that support most of the weight of the structure. A tailwheel at the very back of the fuselage provides a third ... larger propeller and is more desirable for operations on unimproved fields. With the CG located behind the main landing gear, directional control using this type of landing gear is more difficult while on the ground. This is the main disadvantage…

However, the large surface area of the floats makes the helicopter very sensitive to any departure from coordinated flight. For example, in cruise flight, any yawing causes ... shown in figure 9-4. A failure of the engine requires immediate pedal application to prevent an uncontrollable yaw, with a resulting roll. Figure 9-4. Float instability. Similarly, a tail rotor failure in cruise flight requires immediate entry into…
