Method for reproduction of onboard instrumentation of an aircraft, comprising the steps of connecting a Mission Data Recorder to a Mission Computer of an aircraft having an Operational Flight Program for generating instrument data for onboard instruments; recording instrument data; providing a Mission Debrief System and causing it to reproduce the onboard instruments of the aircraft based on instrument data retrieved from the Mission Data Recorder.

Claims

1. A digital recording and replay system for an aircraft, comprising:

a Mission Computer that is a central part of an avionics system of the aircraft;

an Operational Flight Program stored on the Mission Computer, the Operational Flight Program comprising a dataset defining at least one of a training scenario and a mission of the aircraft, the Operational Flight Program being configured to apply digital signal processing to input source signals representing aircraft parameters and to generate therefrom instrument data for onboard instrument of the aircraft to be presented to an operator or pilot of the aircraft, said instrument data comprising input data transferred to a graphics card of the aircraft and driving a display of the aircraft;

a Mission Data Recorder operatively connected to said Mission Computer configured to record said instrument data; and

a Mission Debriefing System configured to reproduce the onboard instruments by regenerating the display of the aircraft based on said instrument data retrieved from the Mission Data Recorder, wherein the display can be selected or unselected during the training scenario or the mission.

2. A digital recording and replay system for an aircraft according to claim 1, the Mission Data Recorder comprising a first means for receiving a Removable Memory Module configured to store said instrument data.

3. A digital recording and replay system for an aircraft according to claim 2, the Mission Debriefing System comprising a second means for receiving a Removable Memory Module configured to store said instrument data.

4. A digital recording and display system for an aircraft according to claim 3, further comprising a Removable Memory Module configured to store said instrument data, removable from said first means, and insertable into the second means.

5. A digital recording and replay system for an aircraft according to claim 1, wherein the Mission Debriefing System is operatively connectable to said Mission Data Recorder and configured to retrieve said recorded instrument data and subsequently reproduce the onboard instruments of the aircraft within the aircraft using onboard instruments of the aircraft based on instrument data retrieved from the Mission Data Recorder.

6. A digital recording and replay system for an aircraft according to claim 1, wherein said instrument data comprises parameters of an avionics system of the aircraft and wherein said reproduction by the Mission Debriefing System comprises a reconstruction of a display as a pilot would see the display during a flight of the aircraft during which said instrument data has been recorded.

7. A digital recording and replay system for an aircraft according to claim 1, wherein the Mission Computer is configured to send said input data as packets to the Mission Data Recorder.

8. A digital recording and replay system for an aircraft according to claim 7, wherein the Mission Computer is configured to include in said packets a header defining the data contained within said packets.

9. A digital recording and replay system for an aircraft according to claim 7, wherein the Mission Computer is configured to send additional packets to the Mission Data Recorder comprising data of additional aircraft avionics system other than said display.

10. A digital recording and replay system for an aircraft according to claim 1, wherein said instrument data comprises event data generated in response to pilot actions.

11. A digital recording and replay system for an aircraft according to claim 10, wherein said event data is generated from onboard controls of the aircraft.

12. A digital recording and display system for an aircraft according to claim 1, wherein the Operational Flight Program is configured to apply digital signal processing to the input source signals before the Mission Data Recorder records said instrument data.

13. A method of reproducing onboard instrumentation of an aircraft, comprising the steps of:

operatively connecting a Mission Data Recorder to a Mission Computer of an avionics system of the aircraft having an Operational Flight Program;

applying digital processing to input source signals representing aircraft parameters, said digital signal processing being performed by the Operational Flight Program;

generating instrument data for onboard instruments of the aircraft to be presented to an operator or pilot of the aircraft, said instrument data comprising input data transferred to a graphics card of the aircraft and driving a display of the aircraft, wherein said generating is performed by the Operational Flight Program;

recording said instrument data generated by the Mission Computer using said Mission Data Recorder; and

reproducing the onboard instruments by regenerating the display of the aircraft with a Mission Debrief System based on instrument data retrieved from the Mission Data Recorder, wherein the display can be selected or unselected during the training scenario or the mission.

14. A method of reproducing onboard instrumentation of an aircraft according to claim 13, wherein the Mission Data Recorder comprises a first means for receiving a Removable Memory Module configured to store said instrument data, and further comprising the steps of inserting a Removable Memory Module configured to store said instrument data into said first means, and storing said instrument data in the Removable Memory Module.

15. A method of reproducing onboard instrumentation of an aircraft according to claim 14, wherein the Mission Debriefing System comprises a second means for receiving said Removable Memory Module, and further comprising the steps of:

removing the Removable Memory Module from said first means; and

inserting the Removable Memory Module into the second means.

16. A method of reproducing onboard instrumentation of an aircraft according to claim 13, wherein the reproducing step includes the steps of:

operatively connecting the Mission Debriefing System to the Mission Data Recorder;

retrieving said recorded instrument data; and

reproducing the onboard instruments of the aircraft within the aircraft using onboard instruments of the aircraft.

17. A method of reproducing onboard instrumentation of an aircraft according to claim 13, wherein said digital signal processing step is performed before said generating step.
