Whats an IAN? Says the guy who gets to look at three lights during a CATIII.

See above link for the gospel. Short story is it makes flying a non precision approach procedurally and visually the same. If you are doing a RNAV approach you just have to ensure a LOC frequency isn't dialed in. The only airport I have gone into where the G/P was way off from the VASI is LAS. Of course the regular ILS G/S is a little funky there too (at least 50 ft high too high over the threshold). With IAN you hit the approach button, ILS like course and path indications pop up and you fly the approach just like an ILS to the non precision minimums.
