Digital Recording and Replay System for an Aircraft and Method for Reproduction of Onboard Instrumentation of an Aircraft

Abstract

Digital recording and replay system (100) for an aircraft, comprising a Mission Computer (MC) with an Operational Flight Program (OFP) for generating instrument data (ID) for onboard instruments of the aircraft; a Mission Data Recorder (MDR) connected to said Mission Computer (MC) for recording said instrument data (ID); and a Mission Debriefing System (MDS); wherein the Mission Debriefing System (MDS) is configured to reproduce the onboard instruments of the aircraft based on instrument data (ID) retrieved from the Mission Data Recorder (MDR). Method for reproduction of onboard instrumentation of an aircraft, comprising the steps of connecting a Mission Data Recorder (MDR) to a Mission Computer (MC) of an aircraft having an Operational Flight Program (OFP) for generating instrument data (ID) for onboard instruments; recording instrument data (ID); providing a Mission Debrief System (MDS) and causing it to reproduce the onboard instruments of the aircraft based on instrument data (ID) retrieved from the Mission MDS Data Recorder (MDR).

Description

PRIORITY[0001]The present application claims priority from PCT / EP2009 / 066449 filed Apr. 12, 2009.FIELD OF THE INVENTION[0002]The present invention relates to a Digital recording and replay system for an aircraft and to a method for reproduction of onboard instrumentation of an aircraft.BACKGROUND OF THE INVENTION[0003]Quite often there is a need to be able to replay / reproduce the exact instrumentation presented to the pilots of an aircraft after a flight. Furthermore, one needs to be able to present this instrumentation in the context of the particular scenario and also to be able to reconstruct the pilot's reaction to the events occurred during the flight. In addition the reaction of an airplane in response to the pilot's actions needs to be documented.[0004]Several systems are known which are able to record aircraft parameters and store instrumentation data as a video and / or audio recording. These systems are known as flight data recorders and cockpit voice / image recorders. They a...

Benefits of technology

[0017]In view of the drawbacks of the prior art, the objective of the present invention and the inventive solution summarized above, the present invention has the main advantage that the data recorded reliably reflects the onboard instrumentation as used by the operator, as opposed to known systems recording merely aircraft parameters that are supposed to result in some expected instrumentation display, while at the same time simplifying the retrieval and minimizing the storage requirements, as compared to a recording of a video image of the instruments which is susceptible to errors in reconstruction, requires significantly more storage capacity and might not even cover all onboard instruments.

Problems solved by technology

One cause for this is the malfunction of the avionics systems of the aircraft which lies at the heart of the computing systems used to process the data.
