Had a quick look, this is a combination of weakness in the position init code, and an explicit design choice in the 'location-in-air' dialog box. Essentially, if you specify start-up position (via the command line or some other property source), and use the --fix or --navaid forms, you'll get a random (actually first by DB order) hit matching the ident. I've considered (and still do) allowing a locale to be established using an airport, country code or similar, or using shutdown location, but it's all a compromise. (If you use frequency and ident, you'll hopefully get an exact match, I haven't checked for duplicates in that case) The dialog box behaviour, is that it explicitly clears out the current lat/lon before doing the navaid/fix search, so we get the same behaviour from the GUI - at least it's consistent. My proposed fix is to add a 'base position' or similar to the properties, and use this as the start point for spatial searches in the position init code. When running from the command line, I'll leave it unset to avoid surprising anyone with new behaviour, but once we're started I'll use the current position, which should make the GUI dialog work as expected. However, I'm not sure doing any of this is wise for 1.99.5, better to do it after the release and let it get some testing, since there's so many permutations of position-init command lines.
