I tested it yesterday and it seems mostly in line with the other IniBuilds aircraft!
The TAB for screen export combines all displays into a single one, but as you did recently with the A330, each screen should be exportable individually.
I loaded the flight from SimBrief, added the SID and STAR, and it duplicated the entire route, giving me a DEST distance of about 117,000 nm. I had to manually delete every waypoint after landing!
I only did one test flight, which I didn’t finish because of a CTD — not sure if it was caused by the PC, the sim, or the aircraft.
