Definition
ZFW is the FAA's three-letter identifier for the Fort Worth Air Route Traffic Control Center (ARTCC), one of the 22 en route centers in the contiguous United States. It provides air traffic control services to aircraft operating on IFR flight plans within its assigned airspace, which covers most of Texas and parts of surrounding states, generally above and between terminal radar areas.
Plain English
ZFW is the short code for the air traffic control facility in Fort Worth that handles high-altitude, long-distance traffic across most of Texas. When you fly IFR through this region, controllers at this center are watching you on radar and giving you instructions while you're between airports.
Context Anchor
Seen in FAA procedure documents, facility references, and ATC-related information when identifying which air traffic control center is responsible for an area.
Derivation
All ARTCC identifiers begin with the letter Z, followed by two letters loosely tied to the center's location. ZFW = Z + FW (Fort Worth). The leading Z distinguishes centers from airports and other facility codes.
Why Pilots Care
Knowing which center owns the airspace you're flying through helps you anticipate handoffs, find the right frequency if you lose comms, and understand route clearances that reference center boundaries.
Intuition Check
Do not read ZFW as a control tower at Fort Worth. It refers to a regional ATC center that controls aircraft across a large area of airspace.
Example Sentence 1
After departing Dallas, the controller handed us off to ZFW for the en route portion of the flight.
Example Sentence 2
ZFW coordinated the handoff as the aircraft climbed through FL180.
