Definition
Air traffic control services provided to a pilot through the use of radar, including traffic advisories, vectoring, sequencing, and separation from other aircraft. Radar services are provided by approach control, departure control, and air route traffic control centers (ARTCC) when the aircraft is identified on the controller's radar display.
Plain English
Help that ATC can give you because they can see your aircraft on their radar screen. This includes telling you about other traffic, giving you headings to fly, fitting you into a flow of arrivals or departures, and keeping you safely separated from other aircraft.
Context Anchor
Seen when communicating with ATC during IFR operations, especially when cancelling an IFR flight plan and deciding whether ATC assistance will continue under VFR.
Derivation
Radar comes from “radio detection and ranging,” meaning finding something and measuring its distance by radio signals. In this phrase, the important point is that the service is not just the radar equipment; it is the help ATC provides by using that equipment.
Why Pilots Care
Keeps you aware of nearby traffic and allows ATC to provide helpful guidance even after switching to visual flight rules.
Intuition Check
Do not read “radar services” as simply “my airplane is visible on radar.” It means ATC is actively providing a service based on that radar information.
Example Sentence 1
After landing at the towered airport, the pilot heard 'radar service terminated, squawk VFR' and knew ATC was no longer tracking the flight.
Example Sentence 2
The controller used radar services to vector me around a busy airport traffic pattern.
