Definition
A ground-based system used by air traffic control that continuously gathers weather radar data from multiple sources, combines it, and converts it into a single integrated weather picture for controllers and traffic management specialists. The RWP supports decisions about routing, sequencing, and traffic flow during convective or hazardous weather.
Plain English
A computer system that pulls in weather radar information as it happens and turns it into one combined picture that air traffic controllers can use to manage traffic around storms and bad weather.
Context Anchor
Seen in FAA acronym lists and in discussions of aviation weather systems that handle current weather information.
Derivation
Real-time means the data is current as events occur, not delayed or after the fact. Processor means a system that takes raw inputs and turns them into something usable. Together: a system that turns live weather data into a usable display.
Why Pilots Care
Gives pilots current weather information needed for safe route, altitude, and timing decisions without waiting for periodic updates.
Intuition Check
Do not read real-time as meaning perfect or guaranteed to match the exact weather at your aircraft. It means the system processes weather information as it is received, but the information can still have limits or delays.
Example Sentence 1
The RWP feed showed a line of strong storms building across the arrival corridor, so traffic management began rerouting flights to the north.
Example Sentence 2
Air traffic control used the RWP feed to advise the flight of a sudden change in visibility at the destination airport.
