It’s definitely different and I quite like it so far! I even flew a pattern behind an airplane I’ve flown IRL. All the traffic was taking off and landing on the correct runway and following the pattern. Models are usually wrong though.
It looks like raw FR24 data to me. I think the airplanes are just sticking where the ADSB feed drops. I kind of wonder if instructors are turning off their transponders right away.
The airport I sim out of is also un-towered, which I think impacts the sim’s logic some. At a towered airport I think they would take direction from the AI tower. MSFS has never implemented the non-tower AI correctly. Mostly the AI airplanes wonder around aimlessly.
