Abstract
A power-on control circuit which functions to inhibit and prevent turn-on of an external power supply to an aircraft, unless a continuity signal is received from the aircraft indicating proper mating of the external power plug in the aircraft socket, thus preventing the hazards of an improper connection. The invention power-on control circuit incorporates a subcircuit for generating an acquisition signal to confirm continuity of connection, and a sensing and detector sub-circuit to enable turn-on of an external power source supplying power to an aircraft. The control circuit contains high ohmic isolation between logic elements and the aircraft, and is not sensitive to coupling with extraneous signals.
