Flight Data Recorder Configuration Signature Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of aircraft systems has increased the difficulty in configuring flight data recorders to record specific parameters, leading to a need for efficient unique identification and management of numerous potential configurations, which is challenging with current methods that rely on assigning multiple part numbers.
Innovation Solution
A method and system that generate a unique signature for a flight data recorder using a configuration profiler, allowing for a graphical user interface to set up a configuration file with a human-readable code and binary image, which identifies customer-specific configurations without changing the core flight data recorder part number, enabling universal and bidirectional identification.

Engineering Contradiction Analysis
1Measurement precision
If multiple part numbers are assigned to control different configurations, then each configuration can be uniquely identified, but the complexity of managing part numbers and controlling hardware/software increases dramatically
Solution Approach 1:
A single part number is used to identify the core flight data recorder hardware, while configuration-specific signatures (generated from configuration files) identify the software/settings variations. This universal part number approach eliminates the need for multiple part numbers, reducing management complexity while maintaining precise configuration identification through the signature system.
2Reliability
If configuration-specific part numbers are used, then government and industry regulations requiring unique identification are met, but the overhead of managing hundreds or thousands of individual part numbers becomes difficult
Solution Approach 1:
The identification system is segmented into two independent components: (1) a universal part number identifying the core hardware, and (2) configuration-specific signatures identifying software/settings. This segmentation allows regulatory compliance through unique signature identification while simplifying operations by eliminating the need to manage multiple part numbers.
Solution Approach 2:
Configuration files serve as an intermediary between the universal part number and the specific configuration settings. These files contain signature information that uniquely identifies each configuration, acting as a mediator that satisfies regulatory requirements without requiring multiple part numbers to be managed.

AI summary
A method and system for identifying a data recorder based upon a unique signature generated for the data recorder. Configuration information is received, the information specifying a plurality of data recording input parameters which are selected to facilitate use of the data recorder in a particular data recording application. A unique signature is generated according for the data recorder, the unique signature including a code which uniquely identifies the data recorder based on a transformation of the configuration information. The unique signature is stored for subsequent access or reference. To differentiate between similar makes and models of data recorders, at least a portion of the unique signature includes a unique core part number that is assigned to only one data recorder by, for example, the manufacturer of the data recorder.
