emteeoh Posted July 11, 2008 Share Posted July 11, 2008 From another thread ( I would say you really need EI to go high, unpressurized Mags start missfiring as you increase altitude. I have had mags (bendix) do OK at FL180, but the current mag I hav starts missfiring at FL150 and is completely dead by the time I get to FL180) I don't get that. Magnetos are basically a magnet, a turning coil, and a cam-operated switch. How would altitude and atmospheric pressure figure into their operation?
