For me personally that was by far the best of the Q&As as it was well structured and this time everyone from the team knew about the wishlist topics or was well prepared. Also I loved the Update by Sebastian on the prop and airflow topic progress which really seems to be a great improvement.
Two key things on props and airflow still remain some mystery to me which I’d love to see answered in the next Q&A, one was asked but Seb did not get it quiet right:
I wonder if downdraft interacts with scenery objects and gets reflected? That would be a key point on helicopters/air taxis/drones landing in between buildings/objects as that is quiet a critical situation irl 
Another thing unclear to me is if wake turbulences are just affected by airflow vs. power or if weight plays a role too. The heavier an aircraft is, the higher the pressure on the wings upper side, the more air gets accelerated downwards on the wings ends from my amateur knowledge 
I think that is actually counted in, but it wasn’t clearly mentioned.
Other than this I’m looking really forward to traffic and ATC related stuff - honestly it would be really great if both are developed from scratch so the overall world behavior reflects real world procedures better 
Passive aircraft right now are simulated way too simplistic and are not interacting with anything close to them (TCAS?). ATC also does not give instructions to keep traffic separated (speeds are just restricted by approaches and departures, not by traffic - also you won’t get vectors to avoid other aircraft if they come close [esp. flying VFR]). As Asobo now got a roadmap on this I’d really like to see it
