Mirror Flight Management Sync for Accurate Offboard Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Flight Management Systems (FMS) and their mirror counterparts, although identical, are disconnected, leading to unreliable data validation due to reliance on initial user-provided data, which may not accurately reflect the aircraft's current conditions.
Innovation Solution
A method and system for offboard data validation where a primary FMS transmits its current parameters and conditions to a mirror FMS, allowing simultaneous data processing and validation of incoming data to ensure integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mirror FMS uses initial user-provided data, then the system complexity is reduced, but the measurement precision of validation deteriorates due to outdated flight conditions
Solution Approach 1:
The system performs preliminary synchronization of flight data from the primary to the mirror FMS before validation processing occurs. This preliminary action ensures the mirror system has current flight conditions (altitude, speed, position, etc.) available for accurate validation, rather than relying on potentially outdated initial data.
Solution Approach 2:
The primary FMS continuously provides feedback data to the mirror FMS in the form of current flight parameters. This feedback loop ensures the mirror system maintains synchronized knowledge of current flight conditions, enabling it to perform accurate real-time validation of incoming data against actual flight state.
2Reliability
If the mirror FMS is kept identical to primary FMS, then the validation capability is improved, but the device complexity increases due to maintaining two separate systems
Solution Approach 1:
The system creates a copy of the primary FMS software baseline for the mirror system. This copy is functionally identical and performs the same processing algorithms, but operates independently for validation purposes. The copying approach enables comprehensive validation capability while avoiding the complexity of developing and maintaining entirely separate validation logic.

AI summary
A method and system for validating data for a Flight Management System (FMS) onboard an aircraft has been developed. Incoming data is received with a primary FMS located onboard the aircraft while the incoming data is simultaneously received with a mirror FMS that is identical to the primary FMS. The current parameters and conditions of the primary FMS are automatically transmitted to the mirror FMS. Next, the incoming data is processed with both the primary FMS and the mirror FMS. The results of the processed data of the primary FMS are then validated with the results of the processed data of the mirror FMS.
