Some more incorrect behavior I’ve just now noticed is that when you first load in cold and dark, the propeller will be feathered, which is correct. However, moving the prop lever forward with the engine still shut down, it’ll push to full fine (which should be impossible) and then won’t feather again.
Haven’t tested it in the Sky Courier but I think I saw in another one of your posts that you’re on that bird currently? I wonder if this is wrong in all the turboprop models. Might add it to a writeup if you’re tracking bugs and incorrect behavior on the 408.
