Definition
A computer system within the National Airspace System that gathers weather data from multiple sources, processes it, and distributes it to air traffic control facilities and weather briefing services. The WCP acts as a central hub that takes raw weather information and routes it to the people and systems that need it.
Plain English
A computer that collects weather information from many places, sorts it, and sends it out to controllers and briefers so everyone is working from the same weather picture.
Context Anchor
Seen in FAA acronym lists and in material about aviation weather information systems, not usually as a term a pilot says on the radio.
Derivation
Weather is the atmospheric conditions; communications comes from Latin communicare meaning to share; processor comes from Latin processus meaning to go forward, here meaning a computer that handles data. Together: a computer that handles and shares weather information.
Why Pilots Care
The weather information a pilot receives during a briefing or hears from ATC often passes through a WCP first. Knowing this helps pilots understand that controllers and briefers are working from the same processed weather feed, not making independent observations.
Intuition Check
Do not read “processor” as a person handling weather reports. Here it means a computer-based system that handles and passes along weather information.
Example Sentence 1
The WCP feeds current weather data to controllers so they can pass timely updates to pilots in flight.
Example Sentence 2
Updates from the WCP reached the flight service station in time for the preflight check.
