I have also seen these "designtor" appraoches for approach plates in other countries. For example, how would an ILS Y 25R @ Quito, Equcador (**made up approach - can't remember the exact approach or where it was that I saw it**) differ from a regular ILS approach??
Thanks in advance!! |
The GPS approach is a bit different from the RNP approach. Most GPS approaches can also be flown as an overlay with ground based navaids. The RNP does not permit that flexibility...and must have certain equipment on board to ensure proper course tracking.
