Ground Station Weather Radar Overlay Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air traffic controllers at ground stations face increased workload due to the lack of real-time weather data, relying on pilot reports which can be inaccurate or incomplete, leading to potential hazards and inefficient decision-making.
Innovation Solution
A system that enables real-time weather data from an aircraft's onboard radar to be shared with the ground station, allowing for a graphical overlay of weather conditions to be displayed, mirroring the aircraft's weather radar display, thereby providing situational awareness without the need for pilot reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If air traffic controllers rely on pilot reports (PIREPs) for weather information, then they can obtain weather data without additional equipment, but the workload increases and accuracy decreases due to manual reporting and interpretation
Solution Approach 1:
The system creates a visual copy of the aircraft's weather radar display at the ground station, allowing air traffic controllers to view the same weather information that the pilot sees. This eliminates the need for pilots to verbally report weather conditions and allows controllers to directly observe accurate, real-time weather data around the aircraft.
Solution Approach 2:
The system introduces an intermediary visual display system that translates the aircraft's radar weather data into a format visible at the ground station. This intermediary display acts as a bridge between the aircraft's sensors and the controller's decision-making process, providing accurate information without requiring manual pilot reporting.
2Loss of information
If air traffic controllers request detailed weather descriptions from flight crew, then they can gather comprehensive weather information, but the flight crew's workload increases during an already demanding operation
Solution Approach 1:
The ground station receives and displays a copy of the weather radar data already being processed by the aircraft's flight display system. This eliminates the need for flight crew to manually describe weather conditions, as the visual information is automatically transmitted and displayed at the ground station in real-time.
Solution Approach 2:
The system allows the aircraft's own weather radar system to serve the dual purpose of both flight operations and ground-based air traffic control assistance. The weather data is automatically captured and transmitted without requiring flight crew intervention, making the system self-sufficient for information gathering.
3Reliability
If air traffic controllers use traditional weather data sources (AIRMET, SIGMET, METAR, NEXRAD), then they can access standardized weather information, but they lack real-time situational awareness of weather conditions around the aircraft
Solution Approach 1:
The system creates a real-time visual copy of the aircraft's onboard weather radar display at the ground station. This provides air traffic controllers with the same real-time weather information that the pilot sees, including the precise location and intensity of weather cells around the aircraft, enhancing situational awareness beyond standardized weather reports.

AI summary
A ground station (220) is used by an air traffic controller to provide support to an aircraft (100). In particular, the ground station may mirror or regenerate a weather radar overlay of a flight display of the aircraft. The air traffic controller and the flight crew may then both see the same real-time weather information with minimum delay and achieve a similar level of situation awareness. The weather radar overlay may be displayed on a display (308) of the ground station. The ground station may receive weather data and ADS-B data or other forms of location data and intended flight path from the aircraft via an air-to-ground communication channel. The weather data may be used to regenerate the weather radar overlay. The ground station may also use the ADS-B data to generate a coverage map of the aircraft in a selected airspace.
