Hi Tom,NCAH, LAT50 and LAT1 are all airways. NCA stands for Northern Control Area, LAT for Lateral. The NCA airways waypoints can be found in the current DAFIF database: https://164.214.2.62/dafif/dafif_0508_mi_av/avdafif/ATS.ZIP (see ATSH.dbf). There you'll find that NCAH goes from MEDPA to YHY (and back) via 7230N070W (N7230), 7130N080W (N7130), 70N090W (N7090), LENOT, and 6352N110W (N6352).LAT50 is listed as NCAL50 in the DAFIF database, and runs from 7130N080W (N7130) to 6430N100W (N6410) via 6830N090W (N6830), and back. LAT1 (NCAL1) is 6430N100W (N6410) TADOM YBE.Cheers,http://home.planet.nl/~duijn181/cu2/koen.jpg
