Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional aircraft displays are used, then the display structure is simple, but the display accuracy and usefulness deteriorate due to complex operating conditions
Solution Approach 1:
The display system dynamically adapts its content based on real-time aircraft conditions. The computing device receives sensor data about aircraft state, configuration, and atmospheric conditions, then updates display indications and limits accordingly. This dynamic adaptation allows the display to maintain high accuracy for blown lift aircraft while managing complexity through automated responses rather than requiring complex manual controls.
Solution Approach 2:
The system incorporates feedback loops where sensor data about actual aircraft performance is continuously fed back to the computing device, which then updates the display to show current indications and limits. This feedback mechanism ensures the display remains accurate and useful by continuously reflecting the actual state of the aircraft in its complex operating conditions.
2Reliability
If real-time updates are provided, then the information accuracy improves, but the system complexity increases
Solution Approach 1:
The computing device automatically processes sensor data and updates display content without requiring pilot intervention. The system self-manages the complexity of real-time calculations, data processing, and display updates, thereby maintaining high information accuracy while avoiding the need for complex manual system management by the pilot.
Solution Approach 2:
The system replaces manual calculation and assessment methods with automated electronic processing. Instead of requiring the pilot to manually compute and interpret complex flight parameters, the computing device automatically processes sensor data and presents simplified, accurate indications and limits on the display, reducing the cognitive load and system complexity from the pilot's perspective.
3Reliability
If multiple indicators and limits are displayed, then the operational safety improves, but the ease of operation deteriorates
Solution Approach 1:
The display is segmented into distinct indications and limits categories, with each element serving a specific function. The computing device organizes complex flight information into separate, manageable components such as current indications, maximum limits, and margins, allowing the pilot to process information systematically without being overwhelmed by a single complex display.
Solution Approach 2:
The display utilizes color coding to convey the status of different flight parameters. By using color changes to indicate proximity to limits, safety margins, and normal operating ranges, the system provides critical safety information at a glance, reducing the pilot's cognitive workload while maintaining high operational safety through intuitive visual cues.
