Plain English Meaning

Fly this exact direction until you are a certain distance from a specific ground station, then the next part of the procedure starts.

Full Definition

A path-and-terminator leg type used in RNAV procedure coding in which the aircraft flies a specified course (a magnetic track) until reaching a defined slant-range distance from a referenced DME station. The leg ends when that DME distance is reached, at which point the next coded leg begins.

Context Anchor

Seen in instrument procedure coding for approaches, departures, and arrivals, especially when describing path and terminator leg types.
