The lazy B had so many things hard and soft coded into the logic and systems with 10,000 so that pilots would not bust the check ride, it took a while to weed it out.
They did eventually fix this, but it took sometime, especially with Jepp as a competitor, so I think you know how that went.
This is why so many of the real challenging airports were AB first.
Cuzco, Lhasa, Linzhi, Queenstown, etc...
I guess this is why the FAA is so insistent on operator and airframe specific validation of the integrity and performance of an RNP AR procedure.
From a pilot's perspective Cuzco is betting on the come, so to speak, because the missed approach is arduous and problematic in the event of an engine failure. I doubt the FAA would approve those Cuzco approaches for a U.S. 121 operator because of the missed approach.
Nonetheless, "buckets" of tourists go from Lima to Cuzco everyday during the season. I suspect the pilots are very conservative about the minimums.
