Maneuver speed
The maneuvering speed (English Design Maneuvering Speed or a. Maximum Maneuvering Speed ; in aviation abbreviated as V A ) is the flight speed (English Indicated Air Speed , IAS) at which the structure of the aircraft to the limit by a full rudder deflection in a symmetrical flight condition the permissible is charged.
meaning
Full rudder deflections are not permitted above the maneuvering speed, as they would overload the aircraft structure. But even below the maneuvering speed, this only applies to the single actuation of one of the three rudders (elevator, aileron or rudder), repeated deflections or combined full deflections of several rudders at the same time can overload the structure even below the maneuvering speed.
The maneuvering speed is often confused with the maximum speed in rough air. This is called V B or V RA (RA for rough air) and is marked on the airspeed indicator with a green (below V RA ) or yellow (above V RA ) arc.
