Aircraft Flight Management System Dynamic Database Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft navigation databases are static and require manual updates every 28 days, limiting the ability to reflect real-time changes in flight procedures and atmospheric conditions, such as runway closures and weather, which can affect flight safety and efficiency.
Innovation Solution
A wireless communication-linked flight management system that dynamically updates navigation databases by requesting and receiving flight procedure data from a remote server, allowing for automatic updates outside of the traditional update cycle, including changes in flight plans and weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updates are performed every 28 days, then database consistency is maintained, but real-time adaptability to changing flight conditions deteriorates
Solution Approach 1:
The system transitions from static periodic updates to dynamic on-demand updates. The FMS automatically requests database updates when needed, allowing the navigation database to adapt dynamically to changing flight conditions while maintaining consistency through controlled update mechanisms.
Solution Approach 2:
The FMS performs self-updating by automatically requesting and receiving database updates from ground stations without requiring manual intervention. This self-service capability enables real-time adaptability while maintaining data consistency through automated update protocols.
2Loss of information
If automatic update requests are implemented, then real-time data availability is improved, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the FMS monitors flight conditions and automatically triggers update requests when changes are detected. This feedback-driven approach ensures real-time data availability while managing complexity through event-triggered updates rather than continuous communication.
Solution Approach 2:
The ground station acts as an intermediary between air traffic control and the FMS, handling the complexity of database updates. This intermediary absorbs the system complexity by managing update protocols, data validation, and synchronization, leaving the FMS with a simplified interface.
3Reliability
If frequent database updates are performed, then flight safety is improved, but maintenance burden increases
Solution Approach 1:
The FMS performs self-updating through automated requests to ground stations, eliminating the need for manual maintenance personnel to update databases frequently. This self-service capability maintains flight safety through real-time updates while reducing maintenance burden by automating the update process.
Solution Approach 2:
The manual mechanical update process is replaced with an automated electronic system. The FMS uses electronic communication to automatically receive and integrate database updates, replacing the manual physical media exchange or manual data entry process with an automated electronic update mechanism.
