I'm sure every airplane is slightly different, but the general statement is that flaps don't change the approach speed too much, only the approach angle.
Very true Rich thats why when I maidened my 767 I had fixed gears and had the flaps at about 20degs, so I knew to keep her at a relativly high throttle level, but now I have retracts & made other improvements the 2nd flight will be VERY interesting . . . . . .I hope
