Airspeed limitation selected by the designer of the aircraft
A flight envelope diagram showing VS (Stall speed at 1G), VC (Corner/Maneuvering speed) and VD (Dive speed)Vg diagram. Note the 1g stall speed, and the Maneuvering Speed (Corner Speed) for both positive and negative g. The maximum “never-exceed” placard dive speeds are determined for smooth air only.
In aviation, the maneuvering speed of an aircraft is an airspeed limitation selected by the designer of the aircraft. At speeds close to, and faster than, the maneuvering speed, full deflection of any flight control surface should not be attempted because of the risk of damage to the aircraft structure.[1]
The maneuvering speed of an aircraft is shown on a cockpit placard and in the aircraft's flight manual but is not commonly shown on the aircraft's airspeed indicator.
In the context of air combat maneuvering (ACM), the maneuvering speed is also known as corner speed or cornering speed.[2]
