Avionics Display Unit Graphical PIREP Icon Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face challenges in interpreting and retaining current meteorological information, particularly turbulence and icing conditions, due to the oral or cryptic alphanumeric nature of Pilot Reports (PIREPs), which can lead to insufficient awareness of adverse weather conditions during flight.
Innovation Solution
An avionics display unit equipped with aircraft receiver circuitry, memory, user interface, PIREP icon generator, map background generator, and display, which receives and decodes PIREP information to generate graphical icons representing meteorological phenomena on a map display, providing pilots with visual and timely updates of weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If PIREP information is presented orally or via alphanumeric messages, then pilots can receive weather updates, but pilots may not retain sufficient information to interpret and remember adverse weather conditions
Solution Approach 1:
The patent transforms PIREP information from oral/alphanumeric form into graphical icon representations that replicate weather conditions visually. The system generates icons that copy the essential characteristics of meteorological phenomena (turbulence, icing, cloud cover) and displays them on a map, enabling pilots to retain and interpret information more effectively through visual recognition rather than verbal processing.
Solution Approach 2:
The patent employs color-coded icons to represent different weather conditions and intensities. By using color changes and variations in icon appearance, the system encodes multiple dimensions of weather information (type, intensity, altitude) into visual cues that pilots can quickly perceive and remember, improving both information retention and ease of interpretation.
2Productivity
If PIREPs are presented in abbreviated alphanumeric format, then weather data can be transmitted efficiently, but the message format becomes difficult to interpret and remember
Solution Approach 1:
The system creates visual copies of weather conditions through graphical icons that directly represent the meaning of abbreviated alphanumeric codes. Instead of requiring pilots to decode cryptic messages, the icons provide immediate visual interpretation of weather conditions, maintaining transmission efficiency while dramatically improving interpretability.
Solution Approach 2:
The patent replaces the mechanical/text-based information transmission system with a visual display system. By substituting alphanumeric coding with graphical representations, the system eliminates the need for pilots to mentally decode abbreviations, making weather information both efficient to receive and easy to understand.
3Measurement precision
If PIREPs are displayed with precise location and timing information, then pilots can accurately locate weather conditions, but the non-regular timing and location make it difficult for pilots to be aware of PIREP existence
Solution Approach 1:
The patent merges multiple PIREP information elements (location, timing, weather type, intensity) into a single integrated graphical display on the map. By combining these discrete data points into unified visual icons that appear on the map at appropriate locations and times, the system makes PIREP existence immediately noticeable to pilots while maintaining precise location and timing information.
Solution Approach 2:
The system adds the visual dimension to PIREP presentation by displaying icons on a graphical map background. This dimensional transformation from text/data to visual space makes PIREPs immediately visible and noticeable to pilots, solving the awareness problem while preserving measurement precision through accurate icon placement and timing indicators.
Data Source
AI summary
An improved avionics display unit graphically presents meteorological phenomena data to a pilot enroute utilizing conventional pilot report (PIREP) information which includes meteorological phenomena data including phenomena location data. The avionics display unit generates an icon defined by the meteorological phenomena data of the PIREP information and presents the icon on a display of the avionics display unit overlaying a map display at an icon location determined in response to the phenomena location data of the PIREP information.
