Abstract

A multifunction avionics server provide for the execution of both certified and uncertified applications in data-serving capacities in which one certified application provides near real-time transmission of flight data recorder type of data. By combining these functions, improved aircraft monitoring is obtained without significant cost or weight penalties.

Claims

1. An avionics server for supplementing black box operation by real-time transmission of black box data comprising:

at least one electronic computer executing a stored program;

an avionics navigation bus interface communicating with the electronic computer;

a flight data recorder bus interface communicating with the electronic computer and adapted to communicate with a flight data recorder; and

a long-range wireless transmitter;

wherein the stored program executes to;

(a) serve flight-related information over the avionics navigation bus to cockpit display devices; and

(b) receive data from the flight recorder bus interface and transmit that data to a receiver remote from an aircraft holding the avionics server using the long-range wireless transmitter.

2. The avionics server of claim 1 wherein flight-related information is in fixed presentations of precomposed data selected from the group consisting of:

electronic pilot manuals, flight checklists, reference documents, equipment lists, and maintenance manuals.

3. The avionics server of claim 2 wherein the fixed presentations of precomposed data are generated by programs executed by the at least one electronic computer and classified as Type-A programs.

4. The avionics server of claim 1 wherein flight-related information is dynamic display information selected from the group consisting of:

moving map displays, dynamic weather charts, and merging and spacing displays.

5. The avionics server of claim 4 wherein the dynamic display information is generated by programs executed by the at least one electronic computer and classified as Type-B programs.

6. The avionics server of claim 1 further including a cockpit environment data interface receiving at least one of cockpit video and cockpit audio data and wherein the stored program further executes to process received cockpit environmental data to provide at least one of a (i) transcription of at least one of voices and aural warnings in the audio data for storage or transmission;

and (ii) are extraction of data from the video for storage or transmission.

7. The avionics server of claim 4 wherein the stored program farther executes to receive an emergency button command from a crew member to increase at least one of frequency and type of the data transmitted to the remote receiver.

8. The avionics server of claim 1 wherein the stored program further executes to detect tampering, with the aircraft as indicated by data received over at least one of the avionics navigation bus and the flight data recorder bus.

9. The avionics server of claim 8 wherein the detection of tampering monitors interruptions of devices normally attached to at least one of the avionics navigation bus and flight data recorder bus to provide at least one of the transmission of information related to the tampering to a crew of the aircraft and/or a transmission of information related to the tampering over the long-range wireless transmitter.

10. The avionics server of claim 1 wherein the interruption is an interruption of communications with the flight data recorder.

11. The avionics server of claim 1 wherein the data transmitted to the receiver remote from the aircraft data includes a timestamp and current aircraft position.

12. The avionics server of claim 1 wherein the program executes to transmit data to the receiver remote from the aircraft in less than 250 milliseconds after the data is received over one of the avionics navigation bus interface and flight data recorder bus interface.

13. The avionics server of claim 1 wherein the long-range wireless transmitter is selected from a SATCOM transceiver, a VHF transceiver, and a HF transceiver.

14. The avionics server of claim 1 wherein the electronic computer provides both a certified and noncertified operating system for executing different portions of the stored program.

15. The avionics server of claim 1 further including a wireless transceiver interface receiving wireless data from a transceiver having a range limited to the aircraft.

16. The avionics server of claim 1 wherein (b) further transmits aircraft information from the avionics navigation bus interface.

17. The avionics server of claim 1 wherein the avionics navigation bus interface conforms to ARINC 717, 429, or Ethernet.

18. The avionics server of claim 1 wherein the flight data recorder bus interface conforms to ARINC 717, ARINC 767 or Ethernet.

19. The avionics server of claim 1 wherein the stored program further executes to analyze data received over at least one of the avionics navigation bus and the flight data recorder bus against rules detecting abnormal or unusual, aircraft operation or activity to increase data transmitted using the ling-range wireless transmitter.
