In truth no. Although it would seem that speed is directly relative to
weight there are other factors that ruin the direct relationship. I've tried
doing this for aircraft I have the full data on and it goes beyond the basic
V2=L.S.U/2.P formula.

Subject: [jhb] V Numbers
Having started to use the Falcon 2000, in FS9, I'm trying to program the
Vspeed gauge.
From the Dassault coverage, plus one flight test, I've managed to get a
few numbers but need more. If I hav eone or two weight to V number sets,
is there a way of extrapolating to other weights?
To be more specific
At "low" take off weight of 18000lbs, Vr = 112 and V2 = 115. Is there a
way of deriving Vr and V2 for 36000lbs?
At the other end, Vref for 18000lbs = 114. At 25000 Vref = 109 What
would be the value at 35800; Max Landing Weight ?
