Abstract

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.

Claims

1. A method for securing a plurality of aircraft, each aircraft having a fuselage cabin with a cockpit, a galley area, adjacent to said cockpit, a main cabin door to the outside, a cockpit door and a galley door, separating the cockpit and galley respectively from the remaining portion of the cabin, said method comprising the steps of:

(a) prior to flight of an aircraft, allowing authorized persons to enter the cockpit;

(b) prior to or during flight of the aircraft, closing and locking the cockpit door to prevent access to the cockpit by unauthorized personnel from the remaining portion of the aircraft cabin;

(c) during flight of the aircraft, removing unauthorized personnel from the galley area;

(d) thereafter closing and locking the galley door to prevent access to the galley by unauthorized personnel from the remaining portion of the aircraft cabin;

(e) thereafter unlocking said cockpit door and allowing authorized personnel into the galley area from the cockpit;

(f) thereafter viewing the galley area for unauthorized personnel;

(g) thereafter unlocking said cockpit door and allowing authorized personnel to reenter said cockpit;

(h) thereafter closing and locking said cockpit door to prevent access to the cockpit by unauthorized personnel;

(i) thereafter unlocking said galley door and allowing unauthorized personnel into the galley area;

(j) repeating steps (c)-(i) as often as necessary;

(k) in the event of a security breach on the aircraft, transmitting an alert between a ground control center and the aircraft; and

(l) transmitting a command from the control center to each of said plurality of aircraft to prevent unlocking of said cockpit door of each aircraft.

2. The method of claim 1, further comprising the step of informing flight attendants that it is allowable to unlock the galley door after said authorized personnel have reentered the cockpit and the cockpit door has been locked.

3. The method of claim 1, wherein said cockpit door includes at least one sensor for indicating when this cockpit door is closed and locked.

4. The method of claim 1, wherein said galley door includes at least one sensor for indicating when this galley door is closed and locked.

5. The method of claim 1, wherein said aircraft has a network node for communicating with the control center and further comprising the step of sending a signal to a said network node in said aircraft indicating when at least one of said cockpit door and said galley door is locked.

6. The method of claim 1, further comprising the step of verifying the identities of the authorized personnel before allowing said authorized personnel to reenter the cockpit.

7. The method of claim 1, wherein the aircraft includes means in the galley area for authorized personnel to enter an alphanumeric code and means responsive to the entered code for unlocking the cockpit door, said method further comprising the step of generating the alphanumeric code in said control center and transmitting said code to said aircraft prior to or during flight.

8. The method defined in claim 7, further comprising the step of verifying the identity of authorized flight personnel at the control center and informing said flight personnel of the alphanumeric code, thereby allowing them to unlock the cockpit door from the galley area side and enter the cockpit.

9. The method of claim 7, further comprising the step of changing the alphanumeric code previously transmitted to each of said plurality of aircraft in flight and transmitting a new alphanumeric code to each of said plurality of aircraft in the event of a security breach in one of said aircraft.

10. The method of claim 1, further comprising the step of transmitting a command from the control center to each of said plurality of aircraft to prevent unlocking of said main cabin door of each aircraft.

11. The method of claim 1, further comprising the step of allowing the unlocking of said cockpit door by authorized personnel in the cockpit after verifying that no security breach exists.

12. The method of claim 11, further comprising the step of verifying that no security breach exists by communicating between said aircraft and said control center.

13. The method of claim 10, further comprising the step of allowing the unlocking of said main cabin door by authorized personnel in the galley area after verifying that no security breach exists.

14. The method of claim 1, wherein the aircraft has a video camera in the cabin for producing a live video signal and wherein said method further comprises the step of transmitting the live video signal from the aircraft to the control center in the event of a security breach.

15. The method of claim 3, further comprising the step of transmitting the indication of the cockpit door sensor from the aircraft to the control center in the event of a security breach.

16. The method of claim 1, wherein the aircraft has a flight recorder for recording current flight information and wherein said method further comprises the step of transmitting the current flight information from the aircraft to the control center in the event of a security breach.
