Here is a listing of the V Speeds we hear quoted so much in technical articles and specifications. Some were a mystery to me so I thought they might be interesting to some of you. If you see any errors, omissions, or would like to comment, please do. Also, if you have an alternate explanation that adds to the understanding of the basic explanation, I'll add that as well. I'll make the corrections to this list to keep it accurate and updated.

V Speeds
Va - Design maneuvering speed
Vfe - Maximum flap extended speed
V1e - Maximum landing gear extended speed
Vmc - Minimum control speed with critical
engine inoperative
Vne - Never-exceed speed (red line)
Vno - Top of green arc
Vso - Stall speed or minimum steady flight
speed obtained in landing configuration
1.3 Vso - Fence speed
Vs1 - Stall speed or minimum steady flight speed
obtained in a specified configuration
Vx - Speed for best angle of climb
Vy - Speed for best rate of climb
Vxse - Best angle of climb speed, one engine
inoperative
Vyse - Best rate of climb speed, one engine
inoperative
V1 - takeoff decision speed
V2 - takeoff safety speed
V2min - minimum takeoff safety speed
Vc - design cruse speed
Vd design dive speed
Vdf - demonstrated dive speed
Vf - design flap speed
Vh - max speed level flight with max cont. power
Vmca - min control speed with critical engine out, out of gnd effect
Vmcg - min control speed with critical engine out, during takeoff run
Vnm - what I am, out of money - Wally
Vmny - An inconvenient and annoying barrier that once reached, limits the speed at which one can build, due to cavitation of the wallet or, in extreme cases possibly even Visa-ne - Metalmaniac
