  • Oil pressure rising when you bring the prop to feather

  • A governor failure not limiting a feathered and stopped prop from unfeathering without cranking the engine

  • Not being able to get the prop to feather even though the props aren't on the stop lock

  • The first should just be a constant in the engine.cfg, which I believe was only set incorrectly by accident in one of my aircraft (Baron Professional?) I'll check my changelogs, but it should be fixed now.

  • I'm not sure exactly what the real world behavior is that you're describing here, but the only type of governor failure that I model in my aircraft is failure to achieve maximum RPM.

  • Assuming you're talking about when shutting down an engine, this could be fixed, and I've looked into it. My propeller simulation is where I fight with the underlying simulation harder than anywhere else, so progress is hard won. I might have an elegant solution to this that I will try before my round of summer updates, but I haven't made any promises in case it gets ugly.
