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…

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…
