Flight Plan TOLD Computation Across Multiple Destinations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight planning systems only perform takeoff and landing data (TOLD) computations for the active flight plan, failing to account for multiple destinations and secondary flight plans, which is necessary for efficient flight operations.
Innovation Solution
A method and system for generating multiple takeoff and landing computations for an aircraft flight plan, including separate calculations for each flight leg, with a flight management system (FMS) analyzing TOLD data and alerting pilots if takeoff or landing is not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If takeoff and landing data computations are performed only for the active flight plan, then the computation process is simple and fast, but the system cannot assess multiple destinations and secondary flight plans
Solution Approach 1:
The system segments the flight plan into multiple discrete legs, each with its own takeoff and landing data computations. The FMS processes each leg independently while maintaining the overall flight plan structure, allowing comprehensive assessment without overwhelming complexity.
Solution Approach 2:
The system performs takeoff and landing data computations for all flight legs in advance during preflight planning, rather than computing them in real-time during execution. This preliminary computation allows the crew to assess all destinations before departure, reducing in-flight workload.
2Reliability
If separate takeoff and landing data computations are performed for each flight leg, then complete assessment of all destinations is achieved, but the computational workload and time increase
Solution Approach 1:
All takeoff and landing data computations for multiple flight legs are performed during the preflight planning phase, well before the actual flight executes. This timing allows sufficient computational resources and time to be dedicated to each leg without impacting flight operations.
Solution Approach 2:
The FMS automatically performs the computationally intensive TOLD analyses for all flight legs without requiring manual intervention or additional crew time during the flight. The system serves itself by utilizing onboard computing resources to complete assessments autonomously.
3Reliability
If the system alerts pilots for every impossible takeoff or landing condition across all flight legs, then flight safety is maximized, but the information overload may distract the pilot
Solution Approach 1:
The FMS provides structured feedback to the pilot through the flight display, presenting TOLD analysis results in a clear, organized format that highlights only the critical information. The system filters and prioritizes alerts based on severity and relevance to current flight operations.
Solution Approach 2:
The system segments safety information by flight leg and by type (takeoff vs. landing), allowing the pilot to review concerns in an organized manner specific to each segment of the journey rather than receiving a single overwhelming list of all potential issues.

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.
