I'll be interested in what others say, but my take on this is:
As far as I know, all the V-speeds you're talking about are a direct
function of stall speed.
For landing, true. For takeoff, not true. Vx and Vy
'Scuse, Peter, but I said "all the V speeds you're talking about",
not "all V-speeds".
As best I can tell, the original poster was talking about
Vr, and landing speed.
I don't think he discussed being asked to climb out at a different
speed than Vx or Vy, but in any event I think a better argument
can be made for that practice in appropriate circumstances.
Now, if you want to argue for Vr being a function of excess thrust
and excess power -- go ahead.
Cheers,
Sydney
