Maneuvering speed

The maneuvering speed ( engl. Design Maneuvering Speed ​​o a maximum Manoeuverspeed, in aviation as a VA for short) is the airspeed (English Indicated Air Speed ​​IAS), in which by a full rudder deflection in a symmetrical flight condition the structure of the aircraft to is charged to the border of the permissible.

Importance

Full rudder deflections are not allowed above the maneuver speed as they would overload the aircraft structure. But even below the maneuvering speed that only applies to the single actuation of one of the three rudder ( elevator, aileron or rudder), repeated eruptions or rashes several combined full rudder at the same time, the structure quite overburden below the maneuvering speed.

The maneuvering speed is often confused with the maximum speed in turbulent air. This is called VB or VRA (RA such as rough air) and is marked on the airspeed indicator with a green (below VRA ) or yellow (above VRA) Arch.

Depending on the flight weight

The VA is also indicated for small aircraft, depending on the flight weight. A high flying weight due to doing a high speed maneuver, a low flying weight rather low speed maneuvers. The heavier the aircraft, the higher VA, because with more fuel in the tanks and consequently higher weight aerodynamic forces resisting the aircraft because of the inertia better. In this case, the distribution of mass between structural and nonstructural parts of plays (ie the wings with the tanks on the one hand and the other hand cockpit ) play a role. These subtleties are usually but not included in the manuals for small aircraft.
