Glide Path Angle Reference Cue for Aircraft Approach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft display systems do not provide a clear and concise method for pilots to determine glide path deviation during approach, relying on complex symbologies and multiple indicators which can be confusing and require attention from the pilot.
Innovation Solution
A system and method for generating glide path information using a glide path angle reference cue (GPARC) and a desired glide path deviation indicator (DGPDI) presented on a pitch scale of an attitude indicator, utilizing symbology data generated from desired glide path and deviation data, allowing pilots to assess glide path deviation from a single reference cue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex symbology and multiple indicators are used to provide glide path information, then the information can be comprehensive and accurate, but the device complexity increases and requires pilot attention
Solution Approach 1:
The patent combines multiple glide path indicators (VASI, PAPI, tri-color VASI, pulsating VASI) into a single integrated display element on the attitude indicator. The symbology generator merges data from multiple sources into one unified visual representation, allowing pilots to assess glide path deviation from a single reference cue rather than multiple separate indicators.
Solution Approach 2:
The attitude indicator display serves multiple functions: it shows attitude information, glide path deviation, and integrates various glide slope indicator types (VASI, PAPI, tri-color, pulsating) into a single universal display interface. This multi-functional approach eliminates the need for separate dedicated glide path indicators.
2Loss of information
If multiple indicators and complex symbology are used, then comprehensive glide path information can be provided, but the ease of operation decreases and requires pilot attention
Solution Approach 1:
The patent merges multiple glide path information sources into a single integrated display on the attitude indicator. The symbology generator combines data from VASI, PAPI, tri-color VASI, and pulsating VASI into one unified visual reference, eliminating the need for pilots to monitor multiple separate indicators and reducing cognitive load.
Solution Approach 2:
The attitude indicator serves as an intermediary display that presents glide path information in a familiar and intuitive format. By displaying glide path deviation within the existing attitude indicator symbology, the system provides comprehensive information while maintaining ease of operation through a well-known reference framework.
Data Source
AI summary
A present novel and non-trivial system and methods for generating and presenting glide path information are disclosed. A symbology generator may be configured to receive first data representative of a desired glide path (“DGP”); receive second data representative of first glide path deviation or third data representative of at least aircraft position; determine second glide path deviation as a function of the DGP and the aircraft position if the second data is not received; and generate symbology data as a function of the DGP and the first glide path deviation or second glide path deviation, where the symbology data is representative of a glide path angle reference cue comprised of a desired glide path deviation indicator. The desired glide path deviation indicator may be comprised of a single geometric symbol or a pattern of a plurality of geometric symbols.
