And maybe this is a similar problem:
IRL, the identifier for Kobelt Airpark is N45. That identifier was changed from 10N sometime between 1995 and 2000. XP11 still shows it on the map as 10N. This airport has no published approaches. Using Navigraph data, the airport also shows up on the map and on the 430 as 10N. When I pick through the Navigraph text files, I do see N45 Kobelt listed in GNS430/navdata folder/Airports.txt. Do you think there is another file with authority above this data file?
Thanks again,
Mark
