    “If flaps are down on takeoff and are abruptly brought up on takeoff can you start to loose control?”

    Of course it’s possible to lose control, but it isn’t inevitable. The way you’d handle it depends on 1) your airspeed, and 2) your altitude.

    In general, if you have sufficient airspeed, you can compensate for the loss of flaps by simply increasing the AoA. If, however, your airspeed is too low, it gets more complicated.

    For the Cessna aircraft, the electric motor raises the flaps slowly enough that the aircraft can usually accelerate to compensate for the loss of lift if the pilot doesn’t panic and try to pitch for altitude. If your altitude is too low, it’s possible the aircraft might touch down again as it accelerates to flying speed. Paying attention and flying the airplane should prevent any loss of control.

    Actually if you make aerial banner towing what they do it is to select full flap until they reach 60 kts on the PA 28 and then they rotate when it is stable they reduce to one point of flap to then move to the runway side to and catch the banner. I was forced to do it but I suggest to don’t do if it is not for something special like this kind of operations. It is riskful and forget to do it on an a lier without flaps you don’t take-off.

    Read some book made by pilot so you will learn more about this staff:
