Runway Awareness System Comparative Display Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aviation systems lack an effective method to provide timely and distinctive alerts to flight crews about the risk of runway overrun during landing, necessitating a system to enhance runway awareness.
Innovation Solution
A runway awareness system that utilizes a flight management system (FMS) to receive and compare operational characteristics of primary and alternative aviation parameters, displaying this information in a comparative layout format on a flight display for the aircrew during approach, integrating with onboard avionics and visual display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a runway awareness system is implemented to provide timely alerts about runway overrun risk, then safety is improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single display interface: it shows primary aviation parameters, alternative aviation parameters, predictive touchdown points, stopping points, and runway overrun risk alerts all together. This multi-functional approach improves safety comprehensively while avoiding the need for multiple separate systems that would increase complexity
Solution Approach 2:
The display is segmented into distinct visual elements: primary parameter display, alternative parameter display, predictive touchdown point indicators, stopping point indicators, and alert regions. This segmentation allows pilots to quickly locate and process specific information without being overwhelmed by a monolithic display, improving safety through better information organization
2Loss of information
If predictive data on touchdown and stopping points is displayed, then pilot situational awareness is enhanced, but information processing complexity increases
Solution Approach 1:
The system calculates and displays predictive touchdown points and stopping points in advance, before the aircraft actually reaches those points. This allows pilots to anticipate future states and make informed decisions proactively, enhancing situational awareness without requiring complex real-time processing during critical moments
Solution Approach 2:
The system acts as an intermediary by processing complex calculations of touchdown and stopping points automatically, then presenting simplified visual indicators to the pilot. This mediator approach handles the information processing complexity internally while providing clear, easy-to-interpret visual output to the pilot
3Ease of operation
If multiple data streams are displayed in comparative layout, then decision-making quality is improved, but display complexity increases
Solution Approach 1:
The display uses asymmetric layout where the primary aviation parameter and its associated predictive data occupy the dominant visual space, while alternative parameters are displayed in a secondary, complementary manner. This asymmetric arrangement helps pilots quickly identify the primary information hierarchy without being confused by equal presentation of all data, improving decision-making while managing display complexity
Data Source
AI summary
Methods and systems are provided for providing a runway awareness system for an aircrew of an aircraft. The method comprises receiving a first data stream that provides operational characteristics of a primary aviation parameter on approach to the runway. A second data stream is also received that provides operational characteristics of an alternative aviation parameter on approach to the runway. The first data stream and the second data stream are then displayed in a comparative layout format on a flight display for the aircrew of the aircraft during the approach to the runway.
