The cockpit access protection system relies on a method whereby the locked cockpit doors of a plurality of aircraft may be unlocked only by authorized personnel within the cockpit (e.g., the pilot and copilot). In the event of a security breach in any one aircraft, the control of the cockpit doors of all aircraft shift to a ground control center which commands all cockpit doors to remain locked until the security breach is removed. In this way, neither flight attendant personnel within the aircraft cabin nor the pilot or copilot within the cockpit can be forced to unlock the cockpit door.
