radar service terminated

A term used by air traffic control (ATC) to inform a pilot that he or she will no longer be provided any of the services that could be received while in radar contact. Radar service is automatically terminated, and the pilot is not advised in the following cases:

i. An aircraft cancels the IFR (instrument flight rules) flight plan, except within Class B airspace, Class C airspace, a TRSA (terminal radar service area), or where basic radar service is provided.

ii. An aircraft conducting an instrument, visual, or contact approach has landed or has been asked to change over to an advisory frequency.

iii. An arriving VFR (visual flight rules) aircraft, receiving radar service to a tower-controlled airport has either landed or has been asked to change over to an advisory frequency.

iv. An aircraft completes a radar approach within Class B airspace, Class C airspace, a TRSA, or where sequencing is provided.
