So how do we shut down a damaged engine?

[Cowboy10uk]

Hi all, I wonder if someone can help me as I’m struggling to sort this out.    Was hit by flak earlier today which required me to shut down and feather the right engine.

 

The process I used was starboard throttle to idle, starboard rpm to minimum, pull starboard fuel cut off, starboard magnetos 1 and 2 to off.  Starboard feather push in and hold. 
 

Yet the engine still seemed to be on, the prop continued to turn at speed, and the flame animation from the exhausts was still visible, which I assume if engine was off, they would stop due to no fuel going into the engine to ignite, and if the props feather, then it shouldn’t windmill.

 

Have I missed something somewhere?
Is the the real behaviour? ( sadly as no flyable Mossie sim england it’s one aircraft I’ve never seen fly so have no idea )

is this a Bug? 
Is it a control setup issue on my system?

 

just wondering if any others have had similar issues, so I can try and solve it.

This is what works for me I have no idea if it’s correct. Chop RPM,chop throttle, once RPM is as low as it will go while windmilling pres and HOLD the feather engine button until the RPM drops to 400 release big red button engine will stop completely. Hope it helps.

This is only working on a good engine. When the aircraft/engine has taken damage it doesn't work.

I stopped, isolated, feathered and pushed the extinguisher on a flak-damaged engine. That stopped the engine but didn't extinguish the fire. Burned for a few minutes until I eventually got shot down.

I remember ED said somewhere that fire extinguishers are still WIP.

Its easier than the method I suggested. Take damage press and hold the big red button, close throttle. As Darryl as already mentioned I couldn’t put out the fire.

I understand what happens to the propeller but what does the feathering button actually do when it’s pressed then? Is it like a toggle?

So it looks like the previous "hold it in" advice is wrong.

Not working for me. Red button gets stuck in depressed state for the duration of the mission and the prop never feathers. 

 

If my engine is undamaged, it works fine.

I wonder if it’s bugging out sometimes or if certain damage wrecks the ability to do it? Early days hopefully the kinks get worked out. o7

All hits to the engine do it. I just had a flight where the damaged engine failed to feather but the good engine feathered like it should.

[Dusty44]

I mean I have managed it in the video above, the left engine is in flames and feathers. I just can’t put out the fire. Another guy I fly with has managed it after taking AA from a U boat and limped home on one in a multiplayer session. I see lots of people posting though so something is off.

Here's what it's like on my end, and it's happened every single time I've taken damage....which is 10~15 flights by now:

Maybe damage was done to system responsible for shuting down engine

[Art-J]

That reminds me good ol' times when pretty much every hit on the P-51 caused prop governor to fail :D.

 

Looks like this time it's the feathering system on the Mossie. Oh well, WIP damage model I suppose, but it's definitely worth reporting.

What i know is that feathering system components are the most armor plated thing on multi engine plane, lost engine w/o ability to feather pretty much nail to a coffin.

AAA are damn good shots if they're able to do that 10 missions in a row, if not more.

To feather an engine in the Mossie you require oil pressure and electrics. An electrical boost motor increases the oil pressure to turn the screws. Often damage stops this part. You can get two types of failure, instant and progressive, so I found. If you suspect you are losing oil feather it immediately, because the aircraft becomes un landable with the drag of an unfeathered engine, I never got a landing done that wasn't unsafe.

Oil leaks are simulated in the damage modelling.

There's quite a bit of work to come as I understand about the finer points of the engine management so I personally am expecting changes.
