Prop sync and noise in twins
I note that the Baron (and presumably other twins) has a prop sync switch that
somehow synchronizes the prop speeds on both engines. From recordings I've heard of the interior noise of the aircraft, it does sound as though props that are just slightly out of sync can produce a very irritating intermittent noise as they move in and out of phase. Is it very bothersome in real life? Also, how does the prop sync work? Does it actually move pitch or throttle levers or something? -- Transpose mxsmanic and gmail to reach me by e-mail. |

I was taught and always used the prop control for sync.
