I may be over thinking this or just haven't a clue but here's the question(s). In general, do aircraft designers design flaps to deploy in increments that would graph as an increasing parabolic curve, straight line or decreasing parabolic curve? Does it vary widely? I ask because for fun I often graph the flap increment values in the CFG and get widely differing, sometimes bizarre curves. I would think that in general, flaps of several increments would deploy from small changes to large changes in accordance with decreasing air speeds so what I then do is graph the values in Xcel then adjust them to create a smooth increasing parabolic curve. This sometimes messes with the animations but I wondered if the simulated lift effect would be truer to life that way.
