Anticipated Activation Point for RNP AR Flight Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated flight management systems for RNP AR operations activate monitoring too late, preventing crews from evaluating aircraft capabilities sufficiently upstream of the operation, thereby limiting the ability to adopt alternative strategies if necessary.
Innovation Solution
The method involves calculating and activating an anticipated activation point upstream of the actual activation point, allowing for early evaluation of aircraft capabilities and enabling the implementation of alternative strategies if the foreseen operation is impossible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If monitoring is activated at the application point (current practice), then the system maintains simplicity and follows standard activation protocols, but the crew cannot evaluate aircraft capabilities sufficiently upstream of the operation
Solution Approach 1:
The system calculates an anticipated activation point upstream of the application point and activates monitoring at this earlier location. This preliminary activation allows the crew to evaluate aircraft capabilities before the operation begins, providing time to implement alternative strategies if needed, while maintaining the existing monitoring architecture without adding significant complexity.
2Adaptability or versatility
If monitoring is activated upstream of the application point, then the crew can evaluate aircraft capabilities in advance and implement alternative strategies, but the system complexity increases
Solution Approach 1:
The system performs preliminary calculation of the anticipated activation point based on the application point and activates monitoring earlier, enabling the crew to assess aircraft capabilities and select alternative strategies before the operation begins. The calculation uses existing flight management data without requiring additional complex subsystems.
Solution Approach 2:
The flight management system automatically calculates the anticipated activation point and manages the monitoring activation timeline without requiring manual crew intervention. The system self-adjusts the activation point based on the defined upstream distance, reducing the operational burden on the crew while enhancing adaptability.
3Ease of operation
If the monitoring activation point is delayed, then the system operates with standard procedures, but alternative strategies cannot be implemented timely
Solution Approach 1:
The system activates monitoring at an anticipated point upstream of the application point, providing the crew with advance evaluation time to ensure aircraft capabilities meet safety requirements. This preliminary activation maintains operational simplicity while enhancing safety by enabling timely detection of capability deficiencies and implementation of alternative strategies.

AI summary
Method and device for automatically managing air operations requiring a guarantee of navigation and guidance performance of an aircraft. The device for automatically managing at least one air operation comprises activatable monitoring of the air operation, a computation unit configured to automatically calculate an anticipated activation point as a function of the application point of the air operation, this anticipated activation point being defined upstream of the application point in the direction of flight of the aircraft, and an activation unit configured to automatically activate monitoring and a display when the aircraft reaches, during its flight, the anticipated activation point.
