Thanks for the reply. Reading it 3 days later after I'd remembered what to do after a long, long absence from flying it. The AP/NAV bit.

Managed to import FSC9-created FPs via MSFS, etc, follow the track, etc. Only snag I seem to be hitting is when lining-up for a final, and reducing throttle, all of a sudden, she just loses thrust and just plummets down. Weird.
