?? That's not quite how it works, crab. Theres no such thing as a "valid input" as far as the aircraft is concerned. If the side sticks are moved in opposite directions they will be algebraically summed, I.e. Full fwd/full back inputs would cancel each other out. The only way one would be overridden is if the takeover push button was pressed (which it wasn't at any point as far as I know)
