Rotorcraft Gauge Prioritization for Cockpit Clutter Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cockpits are overwhelmed with multiple gauges, leading to clutter and making it difficult for pilots to focus on critical information from various components, as existing avionics systems do not effectively combine data from multiple sensors into a single, meaningful display.
Innovation Solution
A method to combine multiple sensor inputs into a single gauge output by normalizing the data to a common scale and prioritizing the most critical information for display, allowing a single gauge to represent the status of multiple components, thereby reducing cockpit clutter and enhancing pilot awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple separate gauges are used to monitor different components, then each component's status can be displayed, but the cockpit becomes cluttered and pilots cannot focus on critical information
Solution Approach 1:
The patent combines multiple component status indicators into a single gauge display. Each component (engine, transmission, rotor system) is represented by a segment of the gauge, with colored arcs indicating status levels. This merging approach maintains complete component monitoring while eliminating the clutter of multiple separate gauges, directly resolving the contradiction between information completeness and display simplicity.
Solution Approach 2:
The single gauge serves multiple functions simultaneously: it monitors multiple components (engine, transmission, rotor system), displays various status levels (normal, caution, warning) through color coding, and provides trend information through arc segments. This multi-functionality allows one gauge to replace what would traditionally require multiple specialized gauges, reducing overall system complexity while maintaining comprehensive monitoring capability.
2Reliability
If multiple gauges are installed to monitor all components, then complete monitoring coverage is achieved, but pilot cognitive load increases and critical information becomes difficult to identify
Solution Approach 1:
The gauge applies different visual qualities to different components and status levels. Each component has its own colored arc segment with distinct color coding (green for normal, yellow for caution, red for warning). This local differentiation allows pilots to quickly identify critical issues by color while maintaining awareness of all components, reducing cognitive load while preserving complete monitoring coverage.
Solution Approach 2:
The patent uses color changes to encode component status information efficiently. Green arcs indicate normal operation, yellow arcs indicate caution conditions, and red arcs indicate warning conditions. This color-coding system allows pilots to instantly assess the health of multiple components at a glance, identifying critical issues without requiring detailed analysis of numerical readings from multiple gauges.
3Measurement precision
If traditional separate gauges are used for each component, then detailed component data is available, but physical cockpit space is consumed and layout becomes complex
Solution Approach 1:
The gauge structure nests multiple component indicators within a single circular display. Each component (engine, transmission, rotor system) is represented by a nested arc segment within the overall gauge circle. This nesting arrangement allows detailed component status information to be displayed in a compact format that fits within the space of a single traditional gauge, dramatically reducing the physical display area required while maintaining precise status indication for each component.

AI summary
A rotorcraft gauge display prioritization system (600) for a rotorcraft (100) of a type having at least one gearbox, first and second sensors and a single-output gauge, the system comprising a priority engine (620) configured to receive a first measurement from a first sensor associated with a gearbox (200) and a second measurement from a second sensor associated with a gearbox (200), the first and second measurements both being either temperature measurements or pressure measurements; select a prioritization criterion based on at least the received first and second measurements from the first and second sensors, and select, without user input, one priority measurement for display from the received measurements based on the prioritization criterion selected by the display prioritization system (600), the one priority measurement representing an operating level or value associated with a gearbox of importance to the pilot; and an output engine (630) configured to instruct a single-output gauge (500) disposed within a cockpit to display information representative of the one priority measurement selected by the display prioritization system (600) without user input to the pilot such that the gauge displays only the information representative of the one priority measurement and does not display information representative of any other received measurements so that all of the sensor measurements are combined into the single-output gauge.
