T. Do you know the meaning of the word 'airplane' ? S. Yes, I do. It is 'літак'. T. You are right. There are some words in the English language which have the same meaning. They are aircraft, airliner and aeroplane, plane, for short. S. What does the airplane consist of? T. The airplane consists of five principal structural units: the fuselage, the wing, the tail unit, the landing gear and the power plant. The wing means 'kphjio'. It is the main plane of the aircraft. The word 'plane' has two meanings 'літак' тa 'площина'. S. What is the function of the wing? T. The function of the wing is to support an airplane in the air and to create lift. S. What is the function of the fuselage? T. The function of the fuselage is to carry passengers, crew, cargo, equipment and to support the wing, tail unit and engines in some designs. It also carries the landing gear. S. What is the meaning of the word 'crew'. T. It is 'екіпаж'. 'Cargo' means 'вантаж'. The Ukrainian for 'tail unit' is 'хвостова частина'. There are some synonyms to it. They are: the tail assembly, tail, empennage, fin assembly. The word 'engine' means 'двигун'. The 'landing gear' is 'шасі'. S. What is the function of the tail unit?

T. The function of the tail unit is to provide directional stability and control of the airplane in flight. S. What is the function of the power plant? T. The power plant is a source of power. S. What is the function of the landing gear? T. The landing gear supports the airplane on the ground and its function is also to absorb shocks of landing. I am sure you know the meaning of the word 'land' and 'landing' means 'посадка'.

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.

Exercise 2. Translate word combinations with the term 'aircraft': civil aircraft, cargo aircraft, military aircraft, passenger aircraft, ambulance aircraft, commercial aircraft, sea aircraft, cargo-passenger aircraft, long-range aircraft, forest patrol aircraft, mail-carrying aircraft, search and rescue...
