    I experimented yesterday and abused the engine with the only goal to see what happens when I destroy it. When I managed this even at 0% engine condition the engine didn’t die. It was still producing partial power. Is that the intended „reaction“?

    I finally decided to pull the propeller to fine pitch and land. After I touched down the engine stopped and the propeller was in a feather position which it should have on an single engine piston. It also moved into full coarse pitch with the engine stopped when I moved the Propeller Control forward. Seems odd to me. When the engine is not running the propeller should go to full coarse no matter what the control lever position is dilute to the Return Springs and the lack of oil pressure no?

    Happy flying

      Might your first question be related to this FAQ from the manual?

      Why does the engine not fail when limits are clearly exceeded?

      The “Engine Stress Failure” option must also be enabled in the MSFS Assistance menu for the engine to fail completely.

      There seems to be a little confusion in the second half of your message. I think you just flip-flopped coarse and fine in your description. If I make that assumption, you are correct that the propeller should always go to full fine in a single engine piston aircraft, and not be able to move with loss of oil pressure. It's possible that the windmilling prop was still producing enough oil pressure for some movement during shutdown, but I will have to check on this myself. I'll report back shortly.

        Hi Nick,

        Thanks for clarifying you for clarifying the first point. Sorry for not reading the manual properly.

        On the topic with the propeller your assumption is correct. I flipped fine and coarse.

        Thanks for the prompt reply and for checking on the report
