Non precision MAP fixes are identified in a number of ways:
- Fixes identified by additional terrestrial Navaids eg intersections between the localizer and radial directions from other Navaid beacons like VORs, NDBs, etc..
- Fixes identified by DME slant ranges.
- Fixes identified by flying a linear course from an identified FAF at a specific airspeed for a specific time.
- Fixes identified by area navigation systems.
- Fixes identified by specific GNSS waypoints (RNAV GPS).
For the ILS or LOC/DME rwy 5 KCGZ, when flying the LOC/DME, Your MAP is on localizer at MDA at 7.5 NM DME from the Stanfield (TFD) VORTAC. There is no other means using the equipment required to fly this approach procedure to identify the MAP.
For the LOC rwy 22 into KCDW, your MAP is on localizer at or above MDA when you cross the threshold of rwy 22. Flying the approach at the correct category airspeed, you can also time it using the table in the lower left corner of the plate. But the plate clearly says that the MAP is 5.4 NM from the FAF.
For the ILS or LOC 1 into KILG, the LOC rwy 1 MAP is again on localizer at MDA when the aircraft crosses the threshold of rwy 1. This is defined by the approach timetable on the lower right of the plate.
