Good Morning All - Can any members explain how Lat & Long coordinates are computed for the 757 in FSX - take the ROKU1G STAR for EGNX airport (based on the latest AIRAC cycle). Waypoint ROKUP is described in the STAR db file as 53.017222; -1.515833 yet the actual Lat/Long according to EAG data is N53 01.0 W001 31.0 _ I'm trying to add the respective files for VHHX according to the section of the FMC manual but need to figure out how these coordinates are obtained in the db(s)...Many thanks ::)
