Engineering Contradiction Analysis
1Ease of operation
If a predetermined approach profile is used for landing, then the landing procedure is standardized and easy to follow, but the accuracy of landing distance prediction deteriorates when actual flight conditions deviate from the predetermined profile
Solution Approach 1:
The system dynamically adjusts the approach angle by blending the predetermined approach angle with the actual detected approach angle using a blending factor. This allows the system to transition from a static predetermined profile to a dynamic adaptive profile that responds to actual flight conditions, thereby maintaining prediction accuracy while preserving the benefits of standardized procedures.
Solution Approach 2:
The system continuously detects the actual approach profile during flight and uses this feedback to adjust the effective approach angle calculation. By comparing actual flight data with predetermined values and applying a blending factor, the system incorporates real-time feedback to improve prediction accuracy without abandoning the standardized predetermined profile framework.
2Measurement precision
If only the actual detected approach angle is used, then the prediction reflects real-time flight conditions, but the benefit of predetermined safety margins and standardized procedures is lost
Solution Approach 1:
The system merges the predetermined approach angle (which embodies safety margins and standardized procedures) with the actual detected approach angle (which reflects real-time conditions). By combining these two sources of information through a blending factor, the system preserves both the reliability benefits of predetermined profiles and the accuracy benefits of real-time detection.
Solution Approach 2:
The effective approach angle is computed as a composite value combining predetermined and actual approach angles. This composite parameter integrates the stability and safety margins of predetermined values with the accuracy of real-time measurements, creating a hybrid solution that leverages both sources of information.
3Adaptability or versatility
If the approach angle varies significantly from the predetermined profile, then the system can adapt to unusual flight conditions, but the consistency and predictability of the landing procedure decreases
Solution Approach 1:
The system changes the parameter of approach angle by applying a blending factor that adjusts the weight given to predetermined versus actual values. This parameter adjustment allows the system to adapt to varying flight conditions while maintaining a degree of consistency through the structured blending approach, rather than fully deviating from the predetermined profile.

AI summary
A method of predicting a parameter for an aircraft includes detecting an actual approach profile of the aircraft. The actual approach profile includes an actual approach angle. The method also includes comparing, by a processor, the actual approach profile to a predetermined approach profile to determine a difference between the actual and predetermined approach profiles. The predetermined approach profile includes a predetermined approach angle. The method further includes determining, by the processor, an effective approach angle by combining the actual approach angle and the predetermined approach angle according to a factor that varies based on the difference between the actual and predetermined approach profiles. Moreover, the method includes determining, by the processor, the predicted parameter based on the effective approach angle.
