Assume I want to use the flaps or ailerons at a specific altitude for some maneuevers on an aircraft. We know that the overall aerodynamic forces like lift and drag on an aircraft wing will change values when these control surfaces are used, but the use of these surfaces will also cause a change in the lift/drag distribution on the wing region/area which is located before these control surfaces or not?
I mean the change in the net aerodynamic forces on a wing only result from the usage of these control surfaces, or the force/drag distribution on the immovable wing parts also change and also contribute to the overall change in the lift and drag forces for that wing?
