Aircraft Parameter Display for Anticipating Operating Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots in rotorcraft face challenges in identifying when engine and main power transmission operating parameters are approaching their limits, especially in aircraft without dedicated display screens, leading to increased workload and potential safety risks due to unforeseen limit exceedances.
Innovation Solution
A method and system that utilize sensors to measure operating parameters, generate numerical data, and display them with specific color-coded configurations indicating current intervals relative to limits, allowing pilots to quickly identify approaching limits through consistent symbology across multiple parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pilot monitors numerous instruments on the dashboard to track engine and MPT transmission operating parameters, then the pilot can identify when parameters are approaching limits, but the pilot's workload increases and the complexity of the dashboard increases
Solution Approach 1:
The patent segments the monitoring task by separating the identification of limiting parameters from the display of all parameters. The system automatically identifies which parameter is closest to its limit and presents only that critical information to the pilot, rather than requiring the pilot to monitor all parameters simultaneously on the dashboard.
Solution Approach 2:
The patent introduces an intermediary system (the limitation indicator device) that acts between the multiple monitoring parameters and the pilot. This intermediary automatically processes the parameters, identifies the limiting one, and presents it in a simplified format, reducing the pilot's cognitive load while maintaining reliable identification of approaching limits.
2Reliability
If the pilot uses a dedicated display screen to show current values of operating parameters, then the pilot can see when parameters are approaching limits, but the screen cannot be used for displaying mission information
Solution Approach 1:
The patent makes the limitation indicator device multi-functional by allowing it to display different types of information. The device can show the limiting parameter in various formats (numerical values, graphical representations, color-coded indicators) and can be configured to display different parameters or information types depending on the operational context, while still maintaining its primary function of identifying approaching limits.
3Loss of information
If the system displays all operating parameters continuously on a dedicated screen, then the pilot has complete information, but the screen cannot display mission information and the device complexity increases
Solution Approach 1:
The patent extracts only the most critical information (the limiting parameter) from the full set of operating parameters and presents it separately from the mission information display. This extraction approach provides the pilot with essential parameter information without requiring a dedicated complex display system, as the limitation indicator can integrate with existing display infrastructure.
