Lots of variants outside the U.S. I see Australia has EO procedures associated with their RNP AR approaches.
Of course. AUS was great to design for, instead of studying, the procedures just happened...Those started as the tailored designs for QF, then were made multi-variant to some extent. Most of the good EO missed went away, especially with the temp limitations, because of public outcry with "aircraft on fire" going over their house.
