There is another reason (maybe not in most conventional aircraft magneto
systems) also that used to be used by the automotive boys with dual points
and a coil splitter.
By setting the timing slightly out of phase and running both points
simultaneously, the length of the effective spark can be in
probably customer demand. People have had dual plugs in airplanes so
long, they think it is the best medicine, rather than thinking it through.
But that's just a guess.

An engine with dual ignition is set up to have the flame front within the
cylinder coming from two points in the cylinder, typically top and bottom.? It

Jeff, for smaller volume cylinders, it's a Ford vs Chevy argument about
whether to use one or two plugs per cylinder and the debate will rage on
long after we've passed. I prefer single plug where possible due to 1.
flame front calculations, 2. fewer holes in the head for stronger

That's called an "impulse coupler". One or both mags can have the
