Abstract

An aircraft monitoring system comprising a computer system and a receiver for receiving tracking data from a tracking device associated with an aircraft, the monitoring system having a passive tracking mode in which the computer system is configured to receive tracking data and an active tracking mode in which the computer system is configured to determine a condition indicative of an aircraft incident based on the absence of received tracking data. The monitoring system is automatically triggered into the active tracking mode when a signal is received from the aircraft indicating the aircraft has taken-off.

Claims

1. An aircraft monitoring system comprising a computer system and a receiver for receiving tracking data from a tracking device associated with an aircraft during passive and active tracking modes of operation of the monitoring system, in the active tracking mode the computer system is configured to determine an anomaly in the tracking data that is indicative of an aircraft incident and to generate an alert for transmission to a third party upon determining the anomaly, and wherein the monitoring system is automatically triggered into the active tracking mode from the passive tracking mode when a signal is received from the aircraft indicating the aircraft has taken-off.

2. An aircraft monitoring system according to claim 1 wherein the signal is received from the aircraft after an apparatus on the aircraft determines take-off from any one or more of a change in aircraft speed, a change in aircraft altitude, or a change in distance traveled by the aircraft.

3. An aircraft monitoring system according to claim 2 wherein the apparatus is the tracking device and determines take-off from any one or more of a change in aircraft speed, a change in aircraft altitude or a change in distance traveled by the aircraft.

4. An aircraft monitoring system according to claim 2 wherein the apparatus obtains data from sensors on the aircraft indicative of or from which can be determined any one or more of a change in aircraft speed, a change in aircraft altitude, or a change in distance traveled by the aircraft or other parameter indicating aircraft take-off.

5. An aircraft monitoring system according to claim 1 wherein the signal contains data indicative of or from which can be determined any one or more of a change in aircraft speed, a change in aircraft altitude, or a change in distance traveled by the aircraft indicating aircraft take-off.

6. An aircraft monitoring system according to claim 1, wherein the signal is received from the aircraft after an undercarriage position sensor triggers to indicate aircraft take-off.

7. An aircraft monitoring system according to claim 1 wherein the condition indicative of an incident is the absence of tracking data received from the tracking device in accordance with a transmission regime.

8. An aircraft monitoring system according to claim 1 wherein the tracking data comprises at least position information of the tracking device.

9. An aircraft monitoring system according to claim 1 further comprising a tracking device in the aircraft, wherein the tracking device comprises:

a positioning system for determining position information of the tracking device and/or the aircraft, and

a transmitter for transmitting the position information to the monitoring system.

10. An aircraft monitoring system as claimed in claim 9 wherein the position system is a Global Positioning System (GPS) comprising a GPS receiver and antenna for receiving position information from a GPS satellite.

11. An aircraft monitoring system according to claim 1 wherein upon determining a condition indicative of an incident in the active tracking mode, the monitoring system is adapted to provide an alert.

12. A method for monitoring an aircraft by an aircraft monitoring system the method comprising the steps of:

operating the monitoring system to receive tracking data from a tracking device associated with the aircraft during passive and active tracking modes of operation of the monitoring system, and

automatically triggering the monitoring system into the active tracking mode from the passive tracking mode, when a signal is received by the monitoring system from the aircraft indicating the aircraft has taken off, in the active tracking mode the monitoring system being configured to determine an anomaly in the tracking data that is indicative of an aircraft incident, and generating an alert for transmission to a third party upon determining the anomaly.

13. A method as claimed in claim 12 wherein the signal contains data indicative of or from which can be determined any one or more of a change in aircraft speed, a change in aircraft altitude, or a change in distance traveled by the aircraft indicating aircraft take-off.

14. A method according to claim 12 wherein the condition indicative of an incident is determined based on the absence of tracking data received from the tracking device in accordance with a transmission regime.

15. A method according to claim 12 wherein the step of receiving tracking data from the tracking device comprises receiving positional information of the aircraft.
