I don’t have many hours in but I’ve completed flights fine in the DA62 although I’m using the DA62X and Working Title G1000/3000 mods. I don’t know if the mods are why my flights work though.
I’ve flown the procedure into KACY (Atlantic City) ILS 31 flown on autopilot until very short final for example. It doesn’t seem have any crazy 360’s like what you have there. You should try that one as a test.
Could you post the basics of your flight plan so I could try it? Departure/Arrival and arrival procedure you were trying.
Cheers
Clark
