Default V speeds

You guys most enjoy my posts, you can look smart I was wondering what the V means when your're refering to it as a Vspeed. Like Vref as an example, its your reference speed based on factors of the enviornment at the time, but what does the V mean? I am confused again. any help would be apreciated, thanks.

My logical guess would be Velocity, since V can represent velocity in physics, and velocity is similar to speed. Anyway, I'm glad someone took the time to figure those speeds out, although the only V speed I hate is Vne!

Yea it's really velocity, like Vno is velocity of normal operation(think green arc) in turbulence or max structural cruising speed in turbulence, and Vso-velocity of stall,etc.

Makes sense, look at Vne. Velocity that is not to be exceded. Vrot. Velocity to rotate. Thanks guys.

Vrot? Rotten Speed? Maybe things are different above the Mason Dixon Line, but where i come from, Vr is rotation speed.

Vref and Vt, two speeds that are used a whole bunch is turbine ops aren't really speeds at all. Vref is simply a referance airspeed. It could be referanced to anything, but it is normally used as your final approach speed. Vt or Vtarget is simply a stand in for a target speed which again could be anything. In the RJ (and I think most planes) Vt is actually a take off target speed used for climbing out and accelerating.
