clearance limit

clearance limit

The point to which an aircraft is granted an air traffic control clearance (ICAO). Normally, an aircraft should be cleared for the entire route, but under certain conditions, a short-range clearance procedure is used in which clearance is issued to a fix within or outside of the terminal area. The pilot is advised of the frequency on which he or she will receive further clearance. Coordination has been completed up to that point or will be completed by the time the aircraft reaches that point. Further instructions or clearance will be given at the waypoint or the fix up to point at which the aircraft is cleared.

The article was not detailed on what the carrier crew did (or the IFs for the ILS), but if the clearance limit was the destination airport, the correct action was to first fly to the clearance limit (i.e., the destination airport), and then "upon arrival over" the destination airport (if not EFC) to proceed "to a fix from which an approach begins." Controllers almost always clear you to your destination airport, your clearance limit.
