My point being that altering a wing's camber on T/O will cause havoc if not done with care. I agree with all your points. Slats do ennable Lift, is what I'm sayin. I see it as raising the wing, but effectively lowering the leading edge, creating a stubby high camber high lift wing at a speed the a/c could not otherwise fly at. Are you saying the slats ennable an effective lowering of Incidence, cause that's what I'm saying.
