- VS is the stalling speed, or the minimum steady flight speed at which the airplane is controllable — in other words, the airplane will stall if you fly any slower than this speed.

- Minimum steady flight speed at which the airplane is controllable.
- Nota adicional2
- Although the “stalling speed” part of the definition leads pilots to believe they can avoid a stall by flying at or above a specific numerical value, it is very important to understand that a stall results from exceeding the critical angle of attack. It’s better to think of VS not as a numerical value, but rather the point at which your airplane is at the critical angle of attack in straight-and-level flight. A stall can occur at any airspeed, in any attitude. VS is the point at which the air flowing over the upper surface of the wing can no longer flow smoothly to the trailing edge.
