Lift / Drag
Thanks Westhawk on review you are correct. I was actually thinking of an aborted takeoff where the procedure is to extend the flaps to 40 after decelerating thru 60 knots and if done to soon at higher speeds, the flaps going from a takeoff posistion of 5 to 40 would increase lift and adversely affect braking. I must start posting in the day and not at 4 am.
