Aircraft HSI Spacing Symbology for Intuitive Pilot Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft display systems face challenges in effectively presenting air traffic spacing information to pilots, who already manage numerous flight aspects, making it difficult to intuitively and efficiently convey spacing directions between lead and trailing aircraft.
Innovation Solution
A display system that includes a processing unit to receive and generate display signals for air traffic spacing information, coupled with a display unit rendering a horizontal situation indicator (HSI) using spacing symbology, allowing pilots to visually assess and maintain appropriate spacing relative to a lead aircraft through a linear scale with tolerances and a target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional display systems present multiple types of flight information to pilots, then comprehensive flight management is achieved, but the complexity of information processing increases and intuitive spacing information delivery becomes difficult
Solution Approach 1:
The display system segments spacing information from other flight information and presents it through a dedicated spacing indicator on the HSI display. This separates the critical spacing data from the general flight management information, allowing pilots to quickly identify and process spacing requirements without being overwhelmed by the complete set of flight parameters.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives spacing information from air traffic control or navigation systems, processes it through specific algorithms, and transforms it into visual representations on the HSI display. This intermediary layer acts as a buffer between the raw data and the pilot, simplifying the information presentation while maintaining accuracy.
2Measurement precision
If detailed spacing information is provided to pilots, then spacing accuracy is improved, but the ease of operation and quick comprehension by pilots deteriorates
Solution Approach 1:
The spacing indicator on the HSI display utilizes color variations to convey different spacing statuses. For example, different colors may indicate whether the aircraft is maintaining proper spacing, approaching too closely, or falling behind. This color-coding system allows pilots to quickly assess spacing accuracy at a glance without needing to interpret complex numerical data.
Solution Approach 2:
The patent transforms one-dimensional numerical spacing data into a two-dimensional visual representation on the HSI display. The spacing indicator is positioned relative to the aircraft's flight path and magnetic north, adding spatial context to the spacing information. This dimensional transformation allows pilots to intuitively understand spacing relationships in the context of their current flight orientation.
