Rnav (rnp) 13l 28-feb-2008 Lido Jfk 7-170

Emirates who now use LIDO documents have a RNAV approach to RWY 13L. It is charted as a special procedure requiring airport authorisation and regulatory approval. We fly it in the sim but as far as I know we have not been approved to fly it into JFK.
It works very well, requires a RNP of 0.3 or less and is flown with the A/P coupled down to a DH of 520 feet with the temperature between -7(18f) and 49(121f).
It is a curved approach with the IF at ASALT, FAF at ZADUD 3000' with a constant 3 degree path to the displaced threshold.

Emirates has a couple of these types of approaches now, I think SANNA (Yemen) and Seychelles are similar. The trick to flying them in the SIM anyway is to be ready to engage LNAV with a missed approach otherwise you can quickly find yourself out of the 0.3 RNP ( req for the missed app segment as well).

It is definitely easier and safer, ( less satisfying perhaps) but getting ATC to clear you for these approaches can be difficult as it can conflict with the standard VOR or circling proceedure that most aircraft are equipped to fly.

Happy landings
