Assign headings that will permit final approach course interception on a track that does not exceed the interception angles specified in TBL 5-9-1.
TBL 5-9-1 Approach Course Interception Angle
Distance from interception point to approach gate
Maximum interception angle
Less than 2 miles or triple simultaneous approaches in use
2 miles or more
30 degrees (45 degrees for helicopters)
If deviations from the final approach course are observed after initial course interception, apply the following:
Outside the approach gate: apply procedures in accordance with subpara a, if necessary, vector the aircraft for another approach.
Inside the approach gate: inform the pilot of the aircraft's position and ask intentions.
(Ident) (distance) MILE(S) FROM THE AIRPORT, (distance) MILE(S) RIGHT/LEFT OF COURSE, SAY INTENTIONS.
NOTE: The intent is to provide for a track course intercept angle judged by the controller to be no greater than specified by this procedure.
FAA Order JO 7110.65, Chapter 5, Section 9, Radar Arrivals, and Section 10, Radar Approaches- Terminal.
EN ROUTE. When using a radar scope range above 125 NM, the controller must solicit and receive a pilot report that the aircraft is established on the final approach course. If the pilot has not reported established by the final approach gate, inform the pilot of his/her observed position and ask intentions.
NOTE: It may be difficult to accurately determine small distances when using very large range settings.
