Thank you this really helpsbmbrzmn101 wrote:The simple answer is if the engine is running rough in flight and the pilot determines a mag may be suspect he can switch the mags from both to lt or rt. If it smooths out for instance on the rt mag, he has determined a source of the problem is related to the left mag running on that engine and can continue to run on the single mag until until he can let down to the nearest airport or the nearest airport with a maintenance facility. Actually had the occur in flight in a C45 EN ROUTE to an airshow. Was a loose p lead. Tightened her back up and flew away. Hope this helps.Piper_EEWL wrote:Exactly.

I guess you would turn one of the magnetos of of it has failed or if the ignition timing is off.
