The V+++ abbreviations

[scandtours]

I am sure most of us know what these V.. abbreviations mean.
But for those who don’t know will find this helpful.

VA design maneuvering speed
VB design speed for maximum gust intensity
VC design cruising speed
VD design driving speed
VDF/ MDF demonstrated flight diving speed
VEF the speed at which the critical engine is assumed to fail during a takeoff
VF design flap speed
VFC/ MFC maximum speed for stability characteristics
VFE maximum flap extended speed
VH maximum speed in level flight with maximum continuous power
VLE maximum landing gear extended speed
VLO maximum landing gear operating speed.
VLOF lift-off speed
VMC minimum control speed with the critical engine inoperative
VMO / MMO maximum operating limit speed
VMU minimum unstick speed
VNE never exceed speed
VNO maximum structural cruising speed
VR rotation speed
VS the stalling speed or the minimum steady flight speed at which the airplane is controllable
VSO the stalling speed or the minimum steady flight speed in the landing configuration
VSI the stalling speed or the minimum steady flight speed obtained in a specific configuration
VTOSS takeoff safety speed for Category A rotorcraft.
VX speed for best angle of climb
VY speed for best rate of climb
V1 the maximum speed in the takeoff at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance. V1 also means the minimum speed in the takeoff, following a failure of the critical engine at VEF' at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance.
V2 takeoff safety speed
V2 MIN minimum takeoff safety speed

Haven't seen most of these abbreviations before. I guess if you go past the "V" flight envelope the "V" would be preceded by an "F"

Many of these have non-aviation meanings requiring care in usage around non-pilots.

VA Veteran's Administration
VA The Commonwealth of Virginia, in Post Office form
V1 A buzz bomb of the 1940s
V2 A ballistic missle of the 1940s
VS A decent cognac, but not as good as VSOP
VR virtual reality
VX a nasty nerve gas
VC Victoria Cross, for brave soldiers of the Queen
VC Viet Cong, to American soldiers of a certain age
VD an ailment contracted through intimate relations

VD might be another area of confusion for non pilots
