What is an Aircraft Magneto?

Here at Quality Aircraft Accessories, we specialize in aircraft magnetos and aircraft magneto service. We take pride in our wide breadth of knowledge surrounding aircraft parts and thought we’d share some of that expertise to provide a better understanding of just what an aircraft magneto is and how one works.


An aircraft magneto is an engine driven electrical generator that uses permanent magnets and coils to produce high voltage to fire the aircraft spark plugs. Aircraft magnetos are used in piston aircraft engines and known for their simplicity and reliability. Often sold in pairs, or as a dual magneto, this compact device requires no external electrical source to operate.

Here’s how an aircraft magneto works. Aircraft piston engines are designed with two independent ignition systems. This is made up of two aircraft spark plugs per cylinder and a left and right aircraft magneto. The left aircraft magneto fires one plug per cylinder, while the right aircraft magneto fires the other. This arrangement produces a smoother and more complete combustion of the fuel mixture, while also providing ignition redundancy in the event one aircraft magneto should fail.


There are various models of aircraft magnetos, so understanding which one your engine requires is important. Two of the most common are the Slick Magneto by Champion Aerospace and the Bendix Magneto by Teledyne. These aircraft magnetos are well known across the industry and come from trusted and reputable manufacturers.
