Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If takeoff and landing computations are only performed for the active flight plan, then the computational load is reduced and processing speed is improved, but the safety and reliability deteriorate due to lack of assessment for multiple destinations
Solution Approach 1:
The system performs takeoff and landing computations for all flight legs in advance during flight planning, not just for the active flight plan. This preliminary assessment allows the system to identify potential safety issues before they occur, while the computations are efficiently managed through selective recalculation only when parameters change.
Solution Approach 2:
The flight plan is divided into multiple flight legs, and takeoff and landing computations are performed separately for each leg. This segmentation allows the system to assess safety for each individual segment while managing computational load through selective processing of only those legs whose parameters have changed.
2Reliability
If separate takeoff and landing computations are performed for each flight leg, then the reliability and safety are improved, but the device complexity and computational requirements increase
Solution Approach 1:
All takeoff and landing computations for every flight leg are performed during the flight planning stage before departure. This preliminary action ensures comprehensive safety assessment without increasing in-flight system complexity, as the computations are completed when the flight plan is initially created and stored.
Solution Approach 2:
The flight management system automatically performs and manages the computations for all flight legs without requiring additional manual intervention or complex external systems. The system serves itself by integrating the computation functionality within the existing flight management architecture.
3Measurement precision
If comprehensive TOLD analysis is performed for all flight legs, then the measurement precision and safety assessment are improved, but the loss of time for computation increases
Solution Approach 1:
The system performs comprehensive takeoff and landing computations for all flight legs during the flight planning stage, achieving high measurement precision for safety assessment. By completing these computations beforehand, the system avoids time-consuming calculations during critical flight operations, thus reducing loss of time during actual flight.
Solution Approach 2:
The system dynamically adjusts computation requirements based on whether parameters have changed. During flight, if parameters remain unchanged, the pre-computed data is used without recalculation. Only when parameters change does the system perform updated computations, optimizing the balance between precision and computation time.

AI summary
A method and system for generating multiple takeoff and landing computations for an aircraft flight plan has been developed. First, a flight plan for an aircraft is created that includes multiple flight legs with a separate takeoff and landing. Separate takeoff and landing data (TOLD) for each flight leg is calculated and analyzed to determine if takeoff and landing is possible. The pilot of the aircraft is alerted if takeoff or landing is not possible for a flight leg.
