This report develops revised establishment criteria for the Instrument Landing system (ILS) with approach lights based on benefit/cost analysis, as follows: (1) Air carrier airports with sustained turbojet operations are eligible for an initial ILS (same as previous criteria). (2) At other than jet-use carrier airports and for multiple ILS installations, criteria are expressed as a function of (a) annual instrument approaches by user category, and (b) nonprecision approach minimums on the candidate ILS runway. For example, a runway at a nonhub air carrier airport without turbojet service that has nonprecision approach minimums of 500-1 is an ILS candidate with any combination of 350 air carrier, 375 air taxi, or 1,500 general aviation annual instrument approaches.
