Solution Overview
Problem
Current methods for rotorcraft operators to identify altitude and airspeed combinations to avoid during flight using height-velocity diagrams are time-consuming, effort-intensive, and lack accuracy, especially when parameters change, and not all possible scenarios are covered in manufacturer-provided diagrams.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators use traditional height-velocity diagrams from manuals to identify avoidance regions, then they can obtain safety information, but the process is time-consuming and effort-intensive
Solution Approach 1:
The patent replaces the manual mechanical process of looking up height-velocity diagrams in physical books or binders with an automated electronic system. The processor automatically calculates avoidance regions based on current flight parameters, substituting manual mechanical operations with computational processing. This resolves the contradiction by providing accurate avoidance region identification instantaneously without manual effort.
Solution Approach 2:
The system enables self-service by automatically computing avoidance regions using onboard sensors and processors without requiring operator intervention to consult external materials. The flight management system performs the analysis autonomously, reducing both time and effort while maintaining precision.
2Reliability
If operators manually look up height-velocity diagrams for different flight parameters, then they can find relevant safety information, but the process requires significant effort and is prone to errors
Solution Approach 1:
The patent replaces manual mechanical operations of consulting physical diagrams with automated electronic computation. The system processes flight parameters through algorithms to determine avoidance regions, eliminating manual effort and reducing errors while improving reliability through consistent automated calculations.
Solution Approach 2:
The system continuously monitors flight parameters and provides real-time feedback on avoidance regions through the display interface. This closed-loop feedback mechanism ensures operators receive accurate, up-to-date safety information without manual intervention, improving both reliability and ease of operation.
3Loss of information
If traditional height-velocity diagrams are used, then basic safety information is provided, but real-time, parameter-specific information is not available
Solution Approach 1:
The patent implements a universal flight management system that handles multiple functions: monitoring flight parameters, calculating avoidance regions, and displaying real-time information. This multi-functional system provides complete parameter-specific information without proportionally increasing complexity, as the same hardware platform performs diverse computational tasks.
Solution Approach 2:
The system replaces static mechanical diagrams with dynamic electronic information processing. The processor-based system adapts to different flight conditions and parameters automatically, providing complete real-time information without the complexity of multiple physical reference materials.
4Adaptability or versatility
If manual methods are used to identify avoidance regions, then operators can obtain safety guidance, but the process is not adaptable when flight parameters change
Solution Approach 1:
The patent implements a dynamic system that continuously updates avoidance region calculations as flight parameters change. Unlike static manual diagrams, the electronic system adapts in real-time to varying conditions such as altitude, airspeed, and weight, maintaining accuracy and adaptability without sacrificing response speed.
Solution Approach 2:
The system uses continuous feedback from flight sensors to automatically recalculate and update avoidance regions when parameters change. This real-time feedback loop ensures adaptability to changing conditions while maintaining high productivity through automated processing rather than manual reconsultation.
