The cockpit access protection system relies upon pass codes for an aircraft and utilizes the galley area as a security area to verify a person's identity before allowing access to the cockpit. The system includes normal operation to insure that unauthorized personnel do not gain access to the cockpit. Upon breach of security, the cockpit door is automatically locked by personnel on the ground. A false signal of security breach can be overcome by an authorized flight crew member communicating with ground control upon verification that the report of a false security breach is not made under duress. The system also allows emergency access to the cockpit in the event of a medical or other similar emergency. The method of operating such system is also unique.
