Plain English Meaning

A leg on a published procedure that tells you to fly a specific heading and keep flying it until ATC tells you what to do next.

Full Definition

An ARINC 424 path-terminator leg type that instructs the aircraft to fly a specified heading until the pilot or controller manually terminates the leg, typically by being given a vector, a direct-to clearance, or further routing instructions. The leg has a defined heading but no defined endpoint in the navigation database.

Context Anchor

Seen in instrument procedure database coding, especially where a procedure sends the aircraft on a heading that must be ended by pilot action rather than by reaching a waypoint.
