Thanks for all the feedback. As you say JFK hardly ever use the VOR 13L/R in poor weather and presently most of us maintain 1500' over Canarsie until intercepting the 3 degree path. That should have us cross the MAP at 1220'. A workable LNAV/VNAV database would be a good reference even though it is a visual approach from the MAP. Could I trouble someone from Emirates to send me a chart? Much appreciated
