Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flight crew manually determine optimal timing for approach actions, then they can adapt to non-ideal conditions, but workload and stress increase significantly
Solution Approach 1:
The system performs self-service by automatically calculating and displaying optimal timing for approach actions based on real-time aircraft state and flight plan data. The controller autonomously processes information and generates visual cues, eliminating the need for manual calculation by flight crew and significantly reducing their workload while maintaining adaptability to varying conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring aircraft state parameters and flight plan progress, then dynamically updating visual displays to show optimal timing for actions. This closed-loop feedback mechanism ensures the system adapts to changing conditions in real-time while providing clear, actionable information to the flight crew without increasing their cognitive burden.
2Ease of manufacture
If standard operating procedures are followed rigidly, then procedures are simple, but they cannot accommodate non-ideal conditions effectively
Solution Approach 1:
The system applies dynamics by transforming static standard procedures into dynamic, adaptive guidance. The visual display system continuously updates optimal timing indicators based on real-time aircraft state and flight plan progress, allowing procedures to automatically adapt to non-ideal conditions while maintaining simplicity for the flight crew who simply need to follow the displayed cues.
Solution Approach 2:
The system changes parameters by dynamically adjusting timing parameters for approach actions based on current flight conditions. Instead of fixed procedural steps, the system calculates optimal timing parameters in real-time and displays them visually, enabling procedures to adapt to varying conditions while remaining easy to follow through automated parameter adjustment.
3Adaptability or versatility
If actions are performed under increased workload and stress, then responses to non-ideal conditions improve, but error rates increase
Solution Approach 1:
The system performs self-service by automatically calculating optimal timing and displaying visual cues, which reduces flight crew workload and stress. This automation maintains high adaptability to non-ideal conditions while improving reliability by eliminating errors associated with manual calculation and reducing cognitive load that could lead to mistakes under stress.
Solution Approach 2:
The system implements feedback through continuous monitoring and dynamic visual display updates, providing clear guidance that reduces stress and improves action execution accuracy. The closed-loop feedback mechanism ensures reliable response to non-ideal conditions by continuously adapting guidance based on real-time aircraft state while maintaining low workload for the flight crew.
