Definition
An air traffic control facility that uses radar to provide approach control services to aircraft arriving at, departing from, or transiting the airspace around one or more airports. It sequences and separates traffic, issues vectors, and guides pilots onto final approach courses, typically within roughly 40 miles of the airport and below about 10,000 feet.
Plain English
It is the controller team that watches arriving and departing aircraft on radar near a busy airport and tells pilots which heading, altitude, and speed to fly so everyone stays apart and lines up properly for landing.
Context Anchor
You will encounter radar approach control during radio handoffs near busy airports, especially when flying on instruments or operating in controlled airspace around an airport.
Derivation
Radar comes from the phrase “radio detection and ranging,” meaning finding an object and measuring its distance by using radio waves. Approach here means the phase of flight leading toward an airport, and control means air traffic control guidance, not physical control of the airplane.
Why Pilots Care
Provides radar guidance that keeps arriving and departing aircraft properly spaced in busy airspace.
Intuition Check
Do not read “approach control” as someone taking control of your airplane. It means air traffic controllers are managing aircraft traffic near the airport, while the pilot still flies the aircraft.
Example Sentence 1
About 30 miles out, Center handed us off to the radar approach control, who gave us vectors for the ILS.
Example Sentence 2
Radar approach control sequenced three arrivals behind a departing jet.
