Helicopters

HELICOPTERS

Read the following passage carefully and answer the questions that follow-                                 

Helicopters are very different from aeroplanes. They can do three things that aeroplanes cannot do. First, when aeroplanes move upward, they must also move forward, but helicopters can move straight up without moving ahead. Second, helicopters can fly backwards, which aeroplanes cannot do. Third, helicopters can use their rotors to hover in the air (stay in one place) which is impossible for planes. Because helicopters can perform actions that aeroplanes cannot, they are used for different tasks. Since helicopters can take off without moving forward, they do not need a runway for takeoff. They are used uncongested areas where there is no room for aeroplanes or in isolated areas which do not have airports. Because they can hover, they are used on firefighting missions to drop water on fires. They are used in logging operations to lift trees out of forests. Helicopters are used as air ambulances to airlift patients out of situations which are difficult to reach by conventional ambulances. The police use helicopters to follow suspects on the ground or to search for cars on the ground. Of course, helicopters have military uses because of their design and capabilities.
