First off, this is probably the best airliner ever for MSFS. I was just wondering if it's just me or is there is no external APU sound for this plane?...my earplugs need some use while performing my walkaround :( !Thanks, Dave S

You know i have wondered this too. Sometimes in the FSX version I can hear the engines running, even when they are off. And other times i don't hear anything at all for APU. These may be fixed with the the Update.Peter Osborn

Same here.. Nada!!

Would be nice if this could be added.

Here is the fix.. Go to your PMDG menu and select options/sound. Put a check in the outside sounds option. This worked for me..

Hi all,On certain soundcards there is an issue of engine sounds playing when they are not running (FSX) - when this happens just press "Q" twice to reset the sounds.As for an APU sound - we tried to implement this but it is difficult to add a custom panel sound which only plays back in the external view. We will try to implement this in a future service update if we can overcome this issue.Thanks,Armen

I don't believe that the real MD-11 pilots could here the APU from the Cockpit.

Forget the APU from the cockpit - you can barely hear engine 2 !!! :( This is only about the APU in the external view.

I had the a similar problem with the Grumman Goose. I would hear the engines at full power when I was at idle after switching views. Sound more like an FSX thing than MD-11.
