it sounds wrong,why?
if after takeoff i have a probleme with a ground spoiler bypass valve that prevent the ground spoiler to be in the down position,it add another probleme wich is i cannot raise the landing gear in the most critical phase of flight.
second point is :the takeoff is always made with the spoiler in the down position.in addition even if the ground bypass valve fails to close, the ground spoiler don't raise without actionning the speed brake lever and the airplane must be on ground.
