Exercise 4. Write the correct form of the word in brackets and complete the sentences

International commercial air travel (reach) levels of safety and convenience which (be unimaginable) just a generation ago. Although almost always extremely tragic events, the lessons from accidents (play) an important role in the process (continue) (improve) this safety.

This Lessons Learned from Aviation Accidents library (represent) some of the most major accidents and their (relate) lessons. The U. S. Federal Aviation Administration, with support from many others, (plan) to continue adding to this material on an annual basis. The (object) is (populate) the material with many more of the most historically significant, policy shaping accidents, in order that the lessons that can be learned from their review may be available to all users of the library.

Exercise 5. Look at the following picture. Fill in the blanks.

A. aileron - the hinged surfaces of the trailing edge of a wing (far from the body of the plane) that move up and down in order to roll the plane from side to side.

B. cockpit - where the pilots fly the plane, located at the front of the plane.

C. door - allows people to enter and exit the plane.

D. elevator - the movable part of the 2 horizontal parts of the tail section that moves up or down to help the plane remain level during flight (the elevator controls pitch) and helps control
altitude.

E. fin - the vertical part of the rear of the tail. The rudder is located on the trailing edge of the fin.

F. flaps - the hinged, rear edge of a wing (located near the body of the plane); the flaps move downwards during takeoff and landing in order to increase the wing surface and therefore increase lift.

G. fuselage - the body of the airplane (excluding the wing and tail). Passengers and cargo are carried towards the rear of the fuselage.

H. jet engines - the part of the aircraft that provides the power for the flight.

I. landing gear - the retractable wheels fastened to the main part of the body (by struts) - it is used for landing and moving the plane around on the ground.

J. nose - the forward part of the plane.

K. nosewheel - the part of the landing gear located under the nose of the plane.

L. rudder - the vertical part of the tail; it can move left/right to stabilize the airplane during takeoffs and landings in strong wind or in crosswinds (it controls yaw).

M. slats - the hinged forward edge of a wing; the slats are used during takeoff and landing in order to increase the wing surface and therefore increase lift.

N. spoiler - small hinged plates located on the top surface of the wings; spoilers are used to slow an aircraft or help it descend by disrupting (spoiling) the flow of air around the wing, increasing the drag.

O. windows - sealed viewing portals, located along the sides of the plane.

P. wing - the airplane's two wings produce lift as the plane moves through the air. The wings have four moveable controls: ailerons, flaps, slats, and spoilers.
