Engineering Contradiction Analysis
1Object-affected harmful factors
If an increased ground slope is used during final approach, then environmental impact is reduced and obstacle avoidance is improved, but the risk of hard landings increases
Solution Approach 1:
The invention dynamically adjusts the ground slope parameter during the approach phase based on real-time aircraft state and environmental conditions. By continuously optimizing the ground slope rather than using a fixed increased value, the system achieves environmental benefits while preventing hard landings through adaptive parameter modification.
Solution Approach 2:
The system implements closed-loop feedback by monitoring aircraft vertical speed, ground slope, and other flight parameters, then automatically adjusting the approach trajectory. This feedback mechanism ensures that when hard landing risks are detected, the ground slope is modified to maintain safety while preserving environmental advantages.
2Object-affected harmful factors
If an increased ground slope is used during final approach, then obstacle avoidance is improved, but aircraft maneuverability is compromised
Solution Approach 1:
The invention transforms the static increased ground slope into a dynamic, adaptively adjusted parameter. The system continuously modifies the ground slope based on real-time conditions, providing both obstacle avoidance capabilities and maneuverability when needed, rather than committing to a fixed steep trajectory.
Solution Approach 2:
By changing the ground slope parameter dynamically during approach, the system can transition between steeper trajectories for obstacle avoidance and gentler slopes for improved maneuverability, depending on real-time flight conditions and aircraft state.
3Object-affected harmful factors
If an increased ground slope is used during final approach, then environmental impact is reduced, but significant modifications to aircraft systems are required
Solution Approach 1:
The invention enables the aircraft's existing flight management system to automatically optimize the ground slope using onboard sensors and computational algorithms. This self-service approach eliminates the need for significant structural modifications while achieving environmental benefits through intelligent control of existing systems.
Solution Approach 2:
The invention replaces mechanical/structural modifications with software-based optimization. Instead of physically modifying aircraft systems to handle increased ground slopes, the system uses computational algorithms to dynamically adjust flight parameters, achieving the same effect without hardware changes.
4Object-affected harmful factors
If an increased ground slope is used during final approach, then environmental impact is reduced, but additional pilot training is required
Solution Approach 1:
The system performs automatic ground slope optimization without requiring pilot intervention or specialized training. The flight management system independently calculates and executes optimal trajectories, allowing pilots to operate normally without additional training while still achieving environmental benefits.
Solution Approach 2:
The invention replaces the need for pilot skill development with automated computational optimization. Instead of training pilots to manually manage complex increased ground slope procedures, the system uses algorithms to automatically determine optimal trajectories, eliminating training requirements.

AI summary
Method for optimizing the landing of an aircraft on a runway. According to the invention, a target vertical speed (Vzo) is defined relative to the ground and an optimized ground slope (γo), associated with an approach axis to be followed (A) during landing, is determined as a function of said target vertical speed (Vzo) and at least one external parameter, which is greater than or equal to a predefined ground slope (γi).
