Airplane Components
The major components of an airplane are:
• the fuselage.
• the wings.
• the empennage (tail section).
• the flight controls.
• the landing gear.
• the engine and propeller.
Landing Gear
The landing gear (or undercarriage) supports the weight of the airplane when it is on
the ground, and may be of either the tricycle type (with a nosewheel) or the tailwheel
type. Most tricycle landing gear airplanes are equipped with nosewheel steering through
the rudder pedals, and almost all airplanes have mainwheel brakes.
Engine and Propeller
The engine is usually mounted on the front of the airplane, and separated from the cockpit
by a firewall. In most training airplanes, the engine drives a fixed-pitch propeller, although
more advanced airplanes will have a constant-speed propeller with blades whose pitch can
vary. The engine and its attachments are considered in detail in the next few chapters.
