Definition
The central computer complex host is the main computer system at an FAA Air Route Traffic Control Center (ARTCC) that processes flight data and radar tracking information for en route air traffic control. It receives flight plan data, correlates it with radar returns, and presents the combined information to controllers handling aircraft in the en route environment.
Plain English
The big main computer at an en route air traffic control center that ties flight plans and radar tracks together so controllers can see who is who on their screens.
Context Anchor
Seen in FAA acronym lists, system-status messages, or notices about aviation information systems; it is not a normal cockpit control or flight maneuver term.
Why Pilots Care
When a CCCH outage or slowdown occurs, it can cause delays, route changes, or ground stops because controllers temporarily lose normal flight data processing. Knowing the term helps pilots understand NOTAMs and ATC advisories that reference center computer issues.
Intuition Check
Host does not mean a person hosting an event here. It means a computer that serves other computers or users in a system.
Example Sentence 1
A CCCH outage at the Kansas City Center caused widespread en route delays that morning.
Example Sentence 2
System maintenance on the CCCH may temporarily affect automated flight service functions.
