Abstract

In one example, a method includes capturing, by a camera system including at least one camera device positioned within an aircraft, image data of an interior of the aircraft. The method further includes determining, by a processing device positioned within the aircraft, that one or more alert criteria are satisfied, and outputting, in response to determining that the one or more alert criteria are satisfied, at least a portion of the captured image for transmission to a ground-based computing device via a wireless communications network. The method further includes receiving, from the ground-based computing device, a lock override command configured to cause the processing device to unlock an electronically-controlled door lock of a flight deck door of the aircraft, and responsively unlocking the electronically-controlled door lock of the flight deck door.

First claim

The invention claimed is:

1. A method comprising:
capturing, by a camera system including at least one camera device positioned within an aircraft, image data of an interior of the aircraft;
determining, by a processing device positioned within the aircraft, that one or more alert criteria are satisfied;
outputting, by the processing device in response to determining that the one or more alert criteria are satisfied, at least a portion of the captured image data of the interior of the aircraft for transmission to a ground-based computing device via a wireless communications network;
receiving, by the processing device from the ground-based computing device via the wireless communications network, a lock override command configured to cause the processing device to unlock an electronically-controlled door lock of a flight deck door of the aircraft; and
unlocking, by the processing device in response to receiving the lock override command from the ground-based computing device, the electronically-controlled door lock of the flight deck door;
wherein determining that the one or more alert criteria are satisfied comprises determining that a user-activated unlock override command is active; and
wherein the user-activated unlock override command is activated via an interface located within a flight deck of the aircraft.

2. The method of claim 1 , wherein unlocking the electronically-controlled door lock of the flight deck door overrides a locking command configured to lock the electronically-controlled door lock of the flight deck door.

3. The method of claim 1 , wherein determining that the one or more alert criteria are satisfied comprises determining that a threshold number of unsuccessful unlock attempts of the electronically-controlled door lock of the flight deck door have occurred.

4. The method of claim 1 , wherein determining that the one or more alert criteria are satisfied comprises determining that a threshold number of unlock requests to unlock the flight deck door have occurred without the electronically-controlled door lock of a flight deck door of the aircraft being unlocked.

5. The method of claim 1 , wherein determining that the one or more alert criteria are satisfied comprises determining that a threshold sound level within the interior of the aircraft is exceeded.

6. The method of claim 1 , wherein determining that the one or more alert criteria are satisfied comprises determining that facial feature data included in the captured image data does not correspond to a pre-defined set of facial feature data.

7. The method of claim 1 , wherein determining that the one or more alert criteria are satisfied comprises determining that facial feature data included in the captured image data corresponds to at least one pre-defined set of facial feature data.

8. The method of claim 1 , wherein outputting the at least one portion of the captured image data comprises outputting buffered video data of the interior of the aircraft, a starting time of the buffered video data corresponding to a threshold time period prior to determining that the one or more alert criteria are satisfied.

9. The method of claim 1 ,
wherein the at least one camera device includes at least one cabin camera device positioned with a field of view that includes an area within a cabin of the aircraft proximate the flight deck door; and
wherein outputting the at least one portion of the captured image data comprises outputting at least the captured image data of the at least one cabin camera device.

10. The method of claim 1 ,
wherein the at least one camera device includes at least one flight deck camera device positioned with a field of view that includes an interior of a flight deck of the aircraft; and
wherein outputting the at least one portion of the captured image data comprises outputting the at least one portion of the captured image data of the at least one flight deck camera device.

11. A system comprising:
a camera system including at least one camera device positioned within an aircraft and configured to capture image data of an interior of the aircraft; and
a processing device positioned within the aircraft, the processing device comprising at least one processor and one or more storage devices, the one or more storage devices encoded with instructions that, when executed by the at least one processor, cause the at least one processor to:
determine that one or more alert criteria are satisfied;
output, in response to determining that the one or more alert criteria are satisfied, at least a portion of the image data of the interior of the aircraft captured by the camera system for transmission to a ground-based computing device via a wireless communications network;
receive, from the ground-based computing device via the wireless communications network, a lock override command configured to cause the processing device to unlock an electronically-controlled door lock of a flight deck door of the aircraft; and
unlock, in response to receiving the lock override command from the ground-based computing device, the electronically-controlled door lock of the flight deck door;

wherein the instructions that, when executed by the at least one processor, cause the processing device to determine that the one or more alert criteria are satisfied comprise instructions that, when executed by the at least one processor, cause the processing device to determine that a user-activated unlock override command is activated via an interface located within a flight deck of the aircraft.

12. The system of claim 11 , wherein the instructions that, when executed by the at least one processor, cause the processing device to unlock the electronically-controlled door lock of the flight deck door comprise instructions that, when executed by the at least one processor, cause the processing device to override a locking command configured to lock the electronically-controlled door lock of the flight deck door.

13. The system of claim 11 , wherein the instructions that, when executed by the at least one processor, cause the processing device to determine that the one or more alert criteria are satisfied comprise instructions that, when executed by the at least one processor, cause the processing device to determine that a threshold number of unsuccessful unlock attempts of the electronically-controlled door lock of the flight deck door have occurred.

14. The system of claim 11 , wherein the instructions that, when executed by the at least one processor, cause the processing device to determine that the one or more alert criteria are satisfied comprise instructions that, when executed by the at least one processor, cause the processing device to determine that a threshold number of unlock requests to unlock the flight deck door have occurred without the electronically-controlled door lock of a flight deck door of the aircraft being unlocked.

15. The system of claim 11 , further comprising:
a microphone configured to sense sound within the interior of the aircraft;
wherein the instructions that, when executed by the at least one processor, cause the processing device to determine that the one or more alert criteria are satisfied comprise instructions that, when executed by the at least one processor, cause the processing device to determine that a threshold sound level of sound within the interior of the aircraft sensed by the microphone is exceeded.

16. The system of claim 11 ,
wherein the at least one camera device includes at least one cabin camera device with a field of view that includes an area within a cabin of the aircraft
