What should the flap positions be while taking off?

Mr G. Lee

Sorry, a bit off topic, but I've always wanted to ask a westwind pilot
this.  Why is final segment speed not the same as holding speed ?
After all, the Westwind AFM defines holding speed as "max endurance",
which implies minimum drag, which implies best climb angle speed.
Yet V fs is well above V hold.  Further, V fs should then be slightly less 
than V hold, due to the allowance of engine loss, asymetric thrust and 
rudder drag.

My only explanation is that V fs is not best climb angle.  After all,
there's no certification (that I can find) that requires this.
Although on other aircraft, it seems the manufacturers have taken
advantage of this to get best gradient on the final segment
