What does maneuvering speed, also known as V a, define for an aircraft?

Maneuvering speed, denoted as Va, is a crucial flight parameter that indicates the maximum speed at which an aircraft can be safely controlled without risking structural damage during abrupt control inputs. This speed is especially important during turbulent conditions or in scenarios requiring quick maneuvering, as it allows pilots to apply full deflections of the flight controls without exceeding the aircraft's design limits.

At or below Va, the aircraft will stall before it reaches a load factor that could lead to structural failure. Therefore, knowing this speed helps pilots maintain control and ensures safety during maneuvers. In practice, flying at or below maneuvering speed helps prevent damaging the aircraft while executing sharp turns or rapid altitude changes.
