1Object-generated harmful factors
If flight trajectories are changed to minimize contrail formation, then contrail formation is reduced, but prediction accuracy and reliability remain insufficient due to computational limitations
Solution Approach 1:
The system segments the flight trajectory into multiple adjustable parameters (horizontal position, vertical position, speed, altitude) that can be independently optimized. This allows granular control over flight paths to avoid contrail-prone regions while maintaining overall flight efficiency
Solution Approach 2:
The system performs preliminary contrail likelihood assessment and trajectory optimization before flight execution. By predicting contrail formation risk in advance using weather data and flight parameters, the system can pre-determine optimized trajectories that minimize contrail formation while ensuring reliable predictions through iterative validation
2Measurement precision
If computational models use higher resolution to improve prediction accuracy, then prediction accuracy improves, but computational time increases significantly
Solution Approach 1:
The system applies partial action by focusing computational resources on critical trajectory parameters and contrail-prone regions rather than uniformly high resolution across all dimensions. This selective approach achieves sufficient prediction accuracy while reducing overall computational burden and time requirements
3Use of energy by moving object
If engine design is improved to reduce weight and increase efficiency, then fuel efficiency improves, but cost and environmental footprint increase
Solution Approach 1:
The system enables self-service by providing airlines and operators with accessible tools to optimize their own flight trajectories for contrail reduction. This distributes the optimization function across many individual flight operations rather than requiring centralized engine redesign, achieving aggregate fuel efficiency improvements without the complexity and cost of new engine designs
