Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an on-board parameter-determination module is used to calculate optimized takeoff or landing parameters, then the pilot can directly determine optimized parameters during flight preparations, but the module becomes more complex and may exhibit differences from ground-based flight manual calculations, potentially leading to parameters outside regulatory ranges
Solution Approach 1:
The patent introduces a checking device as an intermediary between the parameter-determination module and the pilot. This checking device validates the optimized parameters against regulatory constraints using a certified flight manual, ensuring that the complex optimization module does not produce non-compliant results while maintaining ease of operation for the pilot
Solution Approach 2:
The checking device provides feedback to the parameter-determination module by validating its outputs against regulatory constraints. If parameters fall outside acceptable ranges, the checking device identifies the violation, allowing the system to adjust or reject the optimized parameters, thus maintaining both optimization capability and regulatory compliance
2Productivity
If iterative optimization methods are used to find maximum takeoff weight and associated speeds, then optimized parameters can be determined considering multiple constraints, but the calculation complexity increases and may lead to results conflicting with predefined regulatory threshold values
Solution Approach 1:
The patent performs preliminary validation of optimized parameters against regulatory constraints using a checking device before finalizing the takeoff or landing. This preliminary check ensures that the results of iterative optimization methods comply with predefined regulatory threshold values, maintaining reliability while preserving optimization efficiency
3Loss of time
If the on-board module uses means for accelerating the calculation, then faster parameter determination is achieved, but the module is no longer certified and may generate erroneous results
Solution Approach 1:
The checking device serves as an intermediary that validates the quickly calculated optimized parameters against a certified flight manual. This allows the system to use fast calculation methods while maintaining reliability through independent verification by the checking device, which uses certified data and methods
