SUREFLY VS. ELECTROAIR: APPLES AND ORANGES

摘要

Pilots all over aviation social media have been touting the SureFly Ignition Module (SIM) mag replacement as the electronic ignition system of choice- and for some, it may be the best choice because of its simple installation. (That's a drop-in SIM mounted next to a traditional mag in the photo to the right.) However, I've seen a lot of forum posts from misinformed buyers who simply overlook the additional benefits afforded by the Electroair ignition. (That's a complete Electroair kit shown in the bottom photo.) One technical aspect focuses on the Electroair's coil pack and high-energy spark. When I mentioned my more efficient starts, Electroair's Mike Kobylik reminded me that the EIS 41000 ignition on my Grumman's Lycoming delivers roughly 70,000 volts to the spark plugs, with a duration of 20 degrees crank rotation.
