By practicing basic fighter maneuvers, you will gain a detailed understanding of movement within the three axes. Stalling In order to fly, an aircraft must have enough thrust to create lift. This thrust translates into a forward velocity. If the aircraft falls below a certain minimum velocity, it will not be able to generate enough lift to stay airbone. In short, it will stall.
Every aircraft has a minimum speed it needs to maintain flight.
This value is called the stall speed, because a stall will occur if the plane's velocity falls below it. This value is usually associated with takeoff and landing since you cross the stall speed in both activities, but actually there are many stall speeds for an individual aircraft. The air pressure is the greatest on the surface and diminishes as you get higher. A plane's landing and takeoff stall speed is applicable near the surface of the earth, but at 50,000 feet the same aircraft will stall at a much different sppeed. The stall speed increases as the aircraft goes higher because the air is thinner.
