The list is in Manufacturer order, so that’s the line that would need to be edited. The ui_manufacturer line in the aircraft.cfg is the source. By default, it uses code to pull a variable from another source that I can’t find. It’s not the manifest.json, I tried that. So I made a backup of the aircraft.cfg from my Bonanza and replaced that entry with a manual one. Starting that with “*” put that plane at the front of the list. But here’s the catch - only the base package planes have an aircraft.cfg that can be edited. You won’t be able to do this with any of the package upgrade planes.
And as always, make a backup of the original file before making any edits!
