    Aircraft stalls on takeoff

    I am on the runway with flaps 22deg, fuel and cargo balanced, speed set to 247k, height 20000, I start to takeoff, I reach130 it starts to lift and takeoff nomatter how I try to keep it on the runway, when I am clear on runway I lift flaps & landing gear but it still goes into a stall, speed is about 180k and the throttles are still wide open, it happens with all jet liners aircraft. Any clues where I am going wrong? !!!! I am thinking of reinstalling again but I dont really want to

    That's what I was aiming for Dean.

    I should have been a little more specific.

    I was wondering if it was the "Over Rotation" that was causing the stall by having too steep a climb rate.

    My betting is that Sam has hit the nail on the head, if you are flying the basic models make sure the flight director is on, then bring up the throttle quadrant, set flaps 15 for takeoff in the 737 or flaps 20 for the 744, then advance the throttles to 50%, then hit the TO/GA button on the throttle quadrant, this will set auto thrust, make sure your autothrust button is switched on in the MCP, then follow the flight director, basically pitching up to the flight director will make you rotate normally, then when you see a positive rate of climb hit the gear up, then when passing 185kts go to flap 10, then when you hit about 200kts go to flap 5, then flap 1 about 220kts, then flap 0 by 235-240kts.
    The key to it is not to have too high a nose attitude, keep it below 18deg, if you follow the flight director you won't have a problem, and don't retract your flaps if you think you are going to stall

    Let us know how you got on

    And make sure your trim is set correctly.

    Simple, don't takeoff with auto-pilot engaged!
