May 7, 2014 - Electroair has received design approval and FAA-PMA for its EIS-61000 series electronic ignition system for Continental 470 and 520 series of engines.
The Electroair kit uses a crankshaft trigger wheel for locating engine position and determining RPM of the engine. The trigger wheel kit offers a highly accurate way of determining engine information with the long-term benefit of needing only a sensor change at the next engine overhaul.
To use this system, a minimum of 0.650-inch of clearance must exist between the crankcase and propeller studs. Electroair has developed and is working through the certification program for a 6-cylinder magneto timing housing (MTH), which removes any limitation that might be experienced with a crankshaft trigger wheel.
The unit was flight-tested on a Cessna 182 (O-470) and demonstrated consistent fuel savings of 1.5-2 gph achieved through its very hot, long-duration spark coupled with the variable timing.
EIS-61000-1C kits are available for immediate shipment, as additional approvals are expected for Lycoming 540 series engines, Continental 360 series, and 550 series engines shortly.
