第5题 (20) 分
Today a pilot is totally dependent on what the air traffic controller on the ground tells him. He can not see enough to be safe. Flightwatch is an instrument intended to help him.
On a screen in front of the pilot, there will be a map of the airspace around the plane. The pilot’s own flight level or height and his own plane at the centre of the screen will show up. On the map any other planes in the airspace will appear
as blobs （点状）of light with “tails” showing the direction of their flight. The flightwatch map is unusual, for the other planes are not shown at their true ranges （范围）, but at their distance away in flying time. That gets over the problem of fast planes being too far away to be seen but likely to make contact in seconds and slow planes that are close enough to be seen but so slow that there’s no chance of contact for, say, ten minutes.
The pilot will be able to see on the screen whether another plane’s course conflicts with his own. The screen will show him the flight number of the other plane, so he can contact air traffic control and ask them about the other plane’s course, then he can take avoiding action if necessary. The screen will show him whether his action puts him in danger from yet another aircraft.
Technically, the system will be quite complex. Computers will be necessary on the ground and in each aircraft to enable flightwatch to collect data about the planes’ courses and to calculate the distances between planes. But such small computers are now quite cheap, simple and reliable.
