KMSP,Minneapolis-St Paul Intl,n44:52:49.965,w093:13:00.920,-3,839,11006I know the field definitions of the above except for the one with the "-3". It has to do with my reply to a post about hand adding airports.ICAO, airport name, lattitude,longitude,???, field elevation in feet,longest runway in feet.I searched the user guide but if it is there I missed it. I'd appreciate the info.

Should have caught on. East is least and West is best (- and +). Thanks.
