2. Make it so engine shutdown and start up become extremely longer making less of an option that people will want to use.
Or, make the engine randomly not restart. Make it a possible consequence of shutting off the engine.
Puma's got it.Read all the WW2 fighter histories you can and see if you can find people intentionally shutting down their engines, particularly over enemy territory. I don't think you'll find any. There might be a couple but it would definitely be the exception to the rule.
Unless they are scouting and listening for tanks ala Battle of the Bulge.

That 'fix' would make it extremely difficult (for me) to hear people on vox.
Even more realism. Sound adjustment is a gamey feature like auto pilot. There are good reasons for both.Exploiting sound adjustment has led to exploiting the sound adjustment exploit.
The actual fix would be removing the ability to adjust sound levels. Shutting off your engine or simply reducing power was possible even if they were poor choices.Never read any WW2 histories where sound levels were tweaked for dogfighting.
