Hi Mathijs,
I wonder if you could elaborate a little on this. This would seem to be rather fundamental to the modelling of turboprop aircraft. i.e. propeller pitch is a range which is used to vary power/thrust and drag. Beta range is a range and not a switch. I think that attempts to simulate changes in propeller pitch with invisible spoilers, while frequently done, and I guess is the only viable alternative, is rather kludgey. Is it your understanding that Asobo are in the process of making the propeller pitch range available to you in the future? Are you having discussions with Asobo regarding this issue?
John.
