Aircraft SystemsHydraulic Systems

• A basic hydraulic system consists of a: • reservoir • pump (either hand,

electric, or engine driven),

• a filter to keep the fluid clean

• selector valve to control the direction of flow

• relief valve to relieve excess pressure

• and an actuator.

Aircraft SystemsLanding Gear

• The landing gear on small aircraft consists of three wheels: two main wheels (one located on each side of the fuselage) and a third wheel positioned either at the front or rear of the airplane.

• Landing gear employing a rear-mounted wheel is called conventional landing gear.

2. It permits better forward visibility for

the pilot during takeoff, landing, and taxiing.

Aircraft SystemsTricycle Landing Gear

3. It tends to prevent ground looping

(swerving) by providing more directional

stability during ground operation since the aircraft’s center of gravity (CG) is forward

of the main wheels.

Aircraft SystemsFixed and Retractable Landing

Gear• Landing gear can be

classified as either fixed or retractable.

• A fixed gear always remains extended and has the advantage of simplicity combined with low maintenance.
