Definition
A U.S. Army air traffic control facility that uses radar to provide approach, departure, and arrival sequencing services to aircraft operating in the airspace around an Army airfield. It performs the same role as a civilian TRACON or a Navy/Air Force RAPCON, but is operated by the Army.
Plain English
An Army-run control facility that watches aircraft on radar and guides them in to land or out on departure at an Army airfield.
Context Anchor
You may see ARAC in FAA acronym lists, military airfield information, or instructions involving flight near an Army airfield.
Derivation
Each word is plain English. The term simply names who runs it (Army), what tool it uses (Radar), and what service it provides (Approach Control).
Why Pilots Care
If you fly into or near an Army airfield, you may be handed off to ARAC for approach or departure control. Knowing it is the Army equivalent of a TRACON tells you what to expect: radar vectors, sequencing, and standard approach control services.
Intuition Check
Do not read ARAC as a type of radar. It refers to the Army control facility or service that uses radar to work aircraft.
Example Sentence 1
Approaching the Army airfield, the pilot was instructed to contact ARAC for radar vectors to the final approach course.
Example Sentence 2
ARAC cleared the flight for the approach after radar identification.
