For MEL purposes, “Dispatch” is defined as the advancement of throttles for the purpose of taking off (takeoff event). If the takeoff is aborted for any reason, the MEL provisions and limitations become applicable once again.
If a component or function becomes inoperative following the takeoff, the MEL does not apply."
