The purpose of trailing edge flaps is to give the aircraft more lift at lower speeds.
But do simple flaps beneficent more than increasing the angle of attack?
The image looks like part of the wing just had it's angle of attack increased, and the other part did not.
Also considering flaps lower a wings critical angle of attack, and increasing the lift coefficient are they really just another way of changing the angle of attack?
If so why do smaller planes use them instead of setting up the landing gear to takeoff/land with greater angles of attack?
