Magnetos

If you’re learning to work on reciprocating aircraft engines, the magneto is one of the most important components of the ignition system to understand. Magnetos have been used on aircraft engines for decades because they are simple, reliable, and—most importantly—do not depend on the aircraft’s electrical system to produce ignition. Understanding magnetos is also important for anyone pursuing an FAA Airframe and Powerplant (A&P) certificate. Magneto operation, inspection, and timing are fundamental Powerplant subjects. ...

Aircraft Magnetos Explained for A&P Students Magnetos are one of the most important parts of a piston aircraft engine ignition system. They are also a common topic in A&P school because they connect several important ideas together: electricity, magnetism, ignition timing, engine operation, and troubleshooting. The big idea is this: An aircraft magneto is a self-contained engine-driven ignition generator that creates the electrical energy needed to fire the spark plugs. ...
