Avionics Display System Automates PIREP Weather Data Formatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face a high workload in collecting and formatting severe weather information for Pilot Reports (PIREPs) due to the complexity of the FAA-approved format, which can discourage them from submitting reports, especially when not equipped with weather radar.
Innovation Solution
An avionics display system that automatically collects and formats weather data from onboard weather radar, presenting it textually and graphically in a PIREP format for pilot review and concurrence, and then transmitting it to a ground station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pilot manually collects and formats weather data for PIREP submission, then the PIREP can be transmitted to ground stations, but the pilot workload increases and the process becomes complex due to remembering the FAA-approved format
Solution Approach 1:
The system automatically collects weather data from onboard sensors and radar, formats it according to FAA PIREP requirements, and prepares it for transmission without requiring pilot intervention. The pilot simply reviews and confirms the automatically generated report, transforming the manual formatting task into an automated self-service process.
Solution Approach 2:
The system performs preliminary data collection and formatting actions before the pilot needs to submit the PIREP. Weather data is continuously monitored and pre-formatted in the background, so when hazardous conditions are detected, the report is already prepared and ready for immediate pilot review and submission.
2Reliability
If a pilot manually formats weather data using the FAA-approved PIREP format with abbreviations, then the report can be transmitted, but the complexity of remembering the format discourages pilots from creating and sending PIREPs
Solution Approach 1:
The system acts as an intermediary between the weather data sensors and the PIREP transmission system. It automatically translates raw weather data into the required FAA PIREP format with proper abbreviations and structure, eliminating the need for the pilot to directly handle the complex formatting requirements while ensuring reliable transmission.
Solution Approach 2:
The manual mechanical process of remembering and applying PIREP format rules is replaced by an automated computer-based system that electronically formats the data. The system stores the FAA PIREP format specifications and automatically applies them, substituting the pilot's mental effort with automated processing.
3Loss of information
If weather data is collected and formatted manually by the pilot, then the PIREP can be submitted, but the process takes time and may delay the dissemination of critical weather information
Solution Approach 1:
The system continuously collects and monitors weather data in real-time, maintaining an ongoing process of data acquisition and preliminary formatting. This continuous operation ensures that when hazardous conditions are detected, the data is already prepared and can be immediately transmitted, eliminating interruptions and delays in the information dissemination process.

AI summary
A system and method for textually displaying weather data on an onboard aircraft display comprises receiving weather data from onboard weather radar. A data collector is coupled to the weather radar and collects relevant data, which is then manipulated to place it in a PIREP (pilot report) format. The formatted data is then rendered on the aircraft display and subsequently transmitted to a ground station.
