"stay in the middle of the air"

From NASA's Civil Helicopter Safety Website:

"Basic Flying Rules:
1. Try to stay in the middle of the air.
2. Do not go near the edges of it.
3. The edges of the air can be recognized by the appearance of ground, buildings, sea, trees and interstellar space. It is much more difficult to fly there."
