Abstract

Various embodiments of the present invention provide a system and method for notifying a flight crew of a fire condition in a cargo container of an aircraft. For instance, particular embodiments involve installing at least one notification device on a cargo container that is in communication with at least one of a fire-detection system or a fire-suppression system for the cargo container. In these particular embodiments, the notification device is configured to emit energy when the fire-detection system detects the fire condition in the cargo container or the fire-suppression system activates as a result of the fire condition. Further, particular embodiments of the invention involve installing at least one detector positioned to detect the energy emitted by the notification device. In these particular embodiments, the detector is configured to send a signal to notify the flight crew of the fire condition after detecting the energy emitted by the notification device.

Claims

1. A system for notifying a flight crew of a fire condition in a cargo container on an aircraft, the system comprising:

at least one infrared light in communication with at least one of a fire-detection system or a fire-suppression system for the cargo container, the infrared light being mounted on an exterior roof of the cargo container and configured to emit infrared energy having a particular emission level when at least one of the fire-detection system detects the fire condition in the cargo container or the fire-suppression system activates as a result of the fire condition in the cargo container; and

at least one infrared detector mounted on the aircraft and positioned to detect the infrared energy emitted by the at least one infrared light and configured to send a signal to notify the flight crew of the fire condition in the cargo container after detecting the infrared energy emitted by the at least one infrared light at the particular emission level, wherein the signal comprises an identifier identifying the infrared detector that sent the signal to enable determination, based in part on the identifier, of which portion of the aircraft comprises the cargo container with the detected fire condition, and

wherein the signal sent by the infrared detector to notify the flight crew of the fire condition causes information on the activation of the fire-suppression system to be recorded.

2. The system of claim 1, wherein the infrared light is a strobe light, and the detector is set to a strobe frequency of the strobe light and is configured to detect the emitted infrared energy based in part on the strobe frequency.

3. The system of claim 1, wherein the signal sent by the infrared detector to notify the flight crew on the aircraft of the fire condition causes information on the activation of the fire-suppression system to be communicated to ground personnel.

4. A system for notifying a flight crew of a fire condition in a cargo container on an aircraft, the system comprising:

at least one notification device in communication with at least one of a fire-detection system or a fire-suppression system for the cargo container in which the at least one notification device is configured to emit energy having a particular characteristic when at least one of the fire-detection system detects the fire condition in the cargo container or the fire-suppression system activates as a result of the fire condition in the cargo container; and

at least one detector positioned to detect the energy emitted by the at least one notification device at the particular characteristic and configured to send a signal to notify the flight crew of the fire condition in the cargo container after detecting the energy emitted by the at least one notification device, wherein the signal comprises an identifier identifying the detector that sent the signal to enable determination, based in part on the identifier, of which portion of the aircraft comprises the cargo container with the detected fire condition, and

wherein (a) the signal sent by the detector to notify the flight crew of the fire condition causes information on the activation of the fire-suppression system to be recorded, (b) the particular characteristic is an emission level, and (c) the emitted energy is at least one of infrared light, laser light, or visible light.

5. The system of claim 4, wherein the emitted energy is not a wireless electrical transmission, a cellular transmission, or a radio frequency transmission.

6. The system of claim 4, wherein the at least one notification device is attached to an exterior of the cargo container and the at least one detector is attached to the aircraft.

7. The system of claim 4, wherein the at least one notification device is mounted on the exterior roof of the cargo container.

8. The system of claim 4, wherein the signal sent to notify the flight crew causes an alarm to sound.

9. The system of claim 4, wherein the signal sent to notify the flight crew causes an indicator light to come on.

10. The system of claim 4, wherein the signal sent to notify the flight crew causes a message to flash across a display.

11. The system of claim 4, wherein the signal sent to notify the flight crew causes information on the activation of the fire-suppression system to be communicated to ground personnel.

12. The system of claim 4, wherein the at least one notification device comprises an infrared strobe light configured to emit the energy as infrared light.

13. The system of claim 4, wherein the signal sent by the detector to notify the flight crew on the aircraft of the fire condition causes information on the activation of the fire-suppression system to be communicated to ground personnel.

21. The method of claim 12, further comprising:

communicating information on the activation of the fire-suppression system to ground personnel.

14. A method for notifying a flight crew of a fire condition in a cargo container on an aircraft, the method comprising the steps of:

emitting energy having a particular characteristic from at least one notification device in communication with at least one of a fire-detection system or a fire-suppression system for the cargo container after at least one of the first-detection system detecting the fire condition in the cargo container or the fire-suppression system activating as a result of the fire condition in the cargo container;

detecting the emitted energy by at least one detector positioned to detect the energy emitted by the at least one notification device at the particular characteristic; and

sending a signal by the at least one detector to notify the flight crew of the fire condition in the cargo container, wherein the signal comprises an identifier identifying the detector that sent the signal to enable determination, based in part on the identifier, of which portion of the aircraft comprises the cargo container with the detected fire condition, and

wherein (a) the signal sent by the detector to notify the flight crew of the fire condition causes information on the activation of the fire-suppression system to be recorded, (b) the particular characteristic is an emission level, and (c) the emitted energy is at least one of infrared light, laser light, or visible light.

15. The method of claim 14, wherein the emitted energy is not a wireless electrical transmission, a cellular transmission, or a radio frequency transmission.

16. The method of claim 14, wherein the at least one notification device comprises at least one infrared light attached to an exterior of the cargo container and the at least one detector is attached to the aircraft.

17. The method of claim 14, wherein the at least one notification device is mounted on the exterior roof of the cargo container.

18. The method of claim 14, wherein the signal sent to notify the flight crew causes an alarm to sound.

19. The method of claim 14, wherein the signal sent to notify the flight crew causes an indicator light to come on.

20. The method of claim 14, wherein the signal sent to notify the flight crew causes a message to flash across a display.

22. The method of claim 14, wherein:

the at least one notification device comprises an infrared strobe light; and

emitting the energy further comprises emitting the energy from the infrared strobe light as infrared light.

23. The method of claim 14, wherein the signal sent by the detector to notify the flight crew on the aircraft of the fire condition causes information on the activation of the fire-suppression system to be communicated to ground personnel.
