That's a real tight arc at Guatemala - 7NM is the PANS OPS minimum, I imagine it is the same for TERPS?
Yes, 7 miles is also the TERPS minimum. But, TERPS provides more lateral protected airspace than does PANS-OPS for an arc.
One major U.S. airline that goes to MGGT considers it a special quals airport. Further, the IAP I posted is the only authorized ILS 1 IAP (there are also base-legs to the ILS.)
This particular air carrier limits speed to a maximum of 170 KIAS upon leaving 10,000 when IMC is anticipated, and final approach airspeed prior to rolling out onto the localizer. Makes sense to me having flown the procedure in Garmin's "simulator."
