Start COAUTL for GSX is the only option I'm seeing
That's not the Couatl Tray bar icon, it's the Couatl icon on the Desktop. The Tray bar is the little icon on the bottom of the screen notification area.
but I am in flight currently but your question makes no sense to me or the suggestion to read page 68 in the manual.
Well, I'd said you should probably have read the manual *before* starting a flight, but that's a completely different issue. You can find the manual here:
\Addon Manager\couatl\GSX\GSX_manual_MSFS.pdf
So you can read it in flight as well.
I reported an issue that I believe is not expected behaviour which is coautl crashes when I reset position. You're asking me if coautl crashes if I restart it?
Yes, I wanted to know if you see a different between restarting from the Tray bar or restarting with "Reset position" or restarting from the "Restart Couatl" button in the GSX menu. There shouldn't be any, in theory, it's always a restart but, obviously, restarting during the middle of a service, expecially passenger+baggage boarding, might be more tricky to do, which is you have other options to Start and Restart.
