Flight Display Runway Alignment Zones for ROAAS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight displays lack the ability to visually represent runway overrun awareness and alerting system (ROAAS) determined information during an approach procedure, making it difficult for flight crews to anticipate where ROAAS alerts will occur along the intended landing runway.
Innovation Solution
A flight display system that integrates a memory and processors to execute a flight display system application, which receives arrival airport and runway data from a ROAAS, displays this information on an airport moving map, and overlays detection zones associated with the aligned runway, enabling crew visualization of anticipated ROAAS alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If flight displays show basic airport and runway information, then the display remains simple and uncluttered, but the crew cannot visualize where ROAAS alerts are anticipated to occur
Solution Approach 1:
The patent overlays detection zone information as a graphical representation on top of the existing airport moving map display. This adds a new dimensional layer of information (ROAAS alert locations) without replacing or complicating the base display structure, allowing crews to see alert anticipation zones in addition to standard runway information.
Solution Approach 2:
The patent introduces an intermediary graphical representation (detection zone overlay) that mediates between the ROAAS system's internal alert data and the crew's need to visualize alert locations. This overlay acts as a visual translator that converts abstract ROAAS data into intuitive spatial information on the display.
2Loss of information
If the flight display overlays detection zones on the airport moving map, then crew situational awareness is enhanced, but the display information density increases
Solution Approach 1:
The patent segments the detection zone information into discrete graphical representations that are overlaid on specific portions of the airport moving map. Each detection zone is displayed as a separate visual element corresponding to its geographical location, allowing crews to process information in manageable segments rather than as a single mass of data.
Solution Approach 2:
The patent applies local quality by displaying detection zone overlays only in the relevant areas of the airport moving map where ROAAS alerts are anticipated to occur. This concentrates information density in specific local regions rather than uniformly distributing it across the entire display, reducing overall information overload while maintaining critical awareness.

AI summary
A flight display provides Runway Alignment Indications on an Airport Moving Map. The Runway Alignment Indications include Landing Runway Detection Zones on the Airport Moving Map for the crew-selected runway or the FMS arrival runway. The Landing Runway Detection Zones are geometrically sized, oriented, and placed in relation to the applicable landing runway approach thresholds.
