What ignition system does a gyroplane engine use?
A dual electronic ignition, two independent capacitor discharge modules each firing its own set of spark plugs. It is a redundancy feature, not a performance one: either circuit alone can keep the engine running if the other fails. Standard on every Rotax engine used in this fleet.
That is the whole entry for now. The longer version, with the mechanics and worked examples, is still to be written. See autorotation for how those read once they exist.
