<![CDATA[Spark plugs fooling, is it simulated at all?]]>Hi,

So I flew a lot my Commander since purchase and I never experienced spark plugs fooling yet. Engine run tests always give more or less the same RPM drops on magnetos, with no particular engine rumble due to a dirty plug.

I tried to let the engine run on ground for one hour full rich, does not change a thing.

With my A2A Comanche doing that will produce spark plugs fooling pretty fast, that’s why I’m wondering if this is really simulated or not.

Thanks!

I’ll do some more tests then.
And sorry for writing « fooling » instead of « fouling ». English is not my native language, at least I learnt something from this topic 😅

The sounds and added effects are new to the 114, and I've ported them back to all my other reciprocating engine aircraft since. You can look at the spark plug illustrations on the engine visualizer for red to see the amount of fouling, as illustrated in the manual. As long as the cylinders are cold, you should see fouling in a few minutes with full rich mixture and low idle power settings.
