I don’t have the courage to write it myself so here is what some people say and exactly what I feel:
« No P factor, no prop wash, odd center of gravity, some planes don’t have asymmetric thrust and those that do, the resulting roll/yaw is minimal. Death stall is not a thing, or most of the departures for that matter. There are tons of things that are wrong.
As a commercial multi engine pilot, my opinion is that the MSFS 2020 flight model is not accurate at all. It’s a beautiful environment to explore but the dynamics are way off. This is especially tru in multi-engine flying. What happens in the sim when you lose one engine on a twin engine aircraft bears no relation to reality. It would be downright dangerous to try to relate any real world flying to this beautiful toy. »
There are many more things like unrealistic weather turbulence and thermals (none), on-rails feeling when landing (what the hell are these slips?), airliners behave like cessnas. But I don’t even want to start talking about specific airplanes, that’s really bad.
