Ive been training to be a professional pilot for 2 years now and if
memory serves me correctly the Private Pilot test asks a question to as
airplanes have a magneto setup, the answer is to provide a totally
redundent ignition system so if the left mag fails you can run of the
right mag, with of course a rpm drop. I would think it would be
incredibly expesive to install one in a car but then again i know little
of automotive ignition systems. On the other hand the more switches and
dials the better (read as cooler).
