How to keep formation when the plane turns?

I don't know if the formation flight you are talking about is an air show of a professional air show team or an air force air show in general. If it is the latter, the planes in the formation should not get close to each other at first, and do not require absolute consistency. Therefore, when it is necessary to turn, just the captain gives the password.

But the professional air show team is very demanding. Not only are the planes very close, only a few meters, but the movements must be absolutely unified, requiring several planes to fly together, just like one plane.

In addition to a lot of training at ordinary times, when performing, the pilots in the back are stuck in the position of leading the plane in front. At the speed of modern jet fighters, the planes are very close, and there are no meters or numbers at all. As long as you look away from the plane in front and look down at the instrument, a major accident like plane collision may happen immediately.

Therefore, the air show team has extremely high requirements on the flight technology and psychological quality of the main pilot, and it must be the top of the top, and every action can't be worse than one second. If the pilot makes a mistake, such as the whole fleet swoops down collectively, and the leading pilot doesn't do the pull rod action according to the specified time, speed and height, then not only will he hit the ground, but all the planes behind him will follow his ass and hit the ground, and no one will be spared.
