> I’ll confess that I don’t know that type of modelling FS2020 is using. But given how it feels, and how it’s the child of FSX, I’m inclined to think it’s using a lookup table
I'll note that this statement is easily disprovable through the two aerodynamics videos that MFS published on Youtube (as another poster here has pointed out).
From what I've seen and read, FS2020's aerodynamics simulation is more advanced than the one in X-Plane.
The issue with aircraft performance might be to do with the current bugs surrounding turboprop engines: https://forums.flightsimulator.com/t/turboprop-engine-logic-...
