Aircraft Parameter Display Cues for Limit Approach Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots of aircraft lack effective methods to identify approaching operational parameter limits without dedicated display devices, leading to increased workload and potential safety risks due to unforeseen limit exceedance.
Innovation Solution
A method and system that measure and display operating parameters using digital data with distinct display configurations indicating current ranges, alerting pilots to approaching limits through color-coded zones on a single page, reducing the need for constant monitoring and comparison with limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots monitor multiple operating parameters using conventional instruments, then they can detect limit exceedance, but their workload increases and response time decreases
Solution Approach 1:
The system uses color-coded display zones (green, yellow, red) to indicate the operational status of parameters relative to their limits. This visual coding allows pilots to quickly assess the state of multiple parameters at a glance without manually comparing values against limit thresholds, thereby reducing workload while maintaining reliable detection of limit exceedance conditions
2Reliability
If pilots manually compare parameter values with limit values, then they can identify approaching limits, but the time required for monitoring increases
Solution Approach 1:
The display system automatically compares current parameter values against their respective limit values and updates the visual indication without requiring pilot intervention. The system self-updates the colored zones based on real-time parameter status, eliminating the need for manual comparison while ensuring continuous monitoring of limit approaches
3Loss of information
If a dedicated display device shows all operating parameter values, then pilots have complete information, but the instrument panel space is consumed and information is scattered
Solution Approach 1:
The system consolidates multiple operating parameter indications onto a single display device with integrated colored zones. Instead of scattering information across multiple separate instruments, the invention combines the display of multiple parameters and their limit status into one unified interface, reducing panel complexity while maintaining complete information availability
