flaps and take off run
Increase in flap setting vs takeoff run.
Fowler type flaps, within the takeoff range will increase lift more than drag and thus increase the take off run. However, if you keep increasing the flap setting out of the takeoff range than the drag will increase greater than the lift and reduce the takeoff range.
A better way to think of it is: Take off ground run increases with flap setting within the take off range, dereases outside of this range.
