Electronic ignition for aircraft piston engines

A Electronic Ignition (PMAG) intended for supplying ignition to an aircraft piston engine, said Electronic Ignition incorporating (a) an internal brush less alternator to provide all necessary electrical power for the ignition while the engine is running, (b) a rotary position encoder to provide engine crankshaft position information, (c) an electronic circuit to calculate proper ignition timing angle and modes of operation, (d) an ignition driver circuit that provides a feedback for closed loop control of ignition coil drive timing and dwell and (e) an ignition coil or coils to fire spark plugs in the engine.
