Text 1. Principal Structural Units of the Airplane
The airplane consists of five principal structural units: the fuselage, the wing, the tail unit, the landing gear and the power plant.
The fuselage extends from the nose to the tail of the airplane. It houses passengers, crew, cargo and equipment. It supports the wing, tail unit and sometimes engines. The fuselage also carries the landing gear.
The wings are lifting and supporting surfaces of the airplane in flight. The function of the wing is to support the airplane in the air and to create lift.
The function of the tail unit is to provide directional stability and control of the airplane in flight. The tail unit consists of two surfaces, vertical and horizontal.
The function of the power plant is to provide power for flight and to propel the airplane.
The landing gear supports the airplane on the ground and its function is to taxi the aircraft on the ground and to absorb the energy of landing.
