How Aircraft Magnetos Work

What is an Aircraft Magneto? An aircraft magneto is an electromechanical device designed to generate electrical energy for the spark plugs in internal combustion engines. The magneto functions autonomously, meaning it is independent of the aircraft’

Understanding how the magneto system works is crucial to understanding how an aircraft piston engine functions. While the magneto is a critical component, it is only one part of the aircraft’s ignition system and the aircraft’s engine itself.

High-tension system magnetos used on aircraft engines are either single or dual type magnetos. The single magneto design incorporates the distributor in the housing with the magneto breaker assembly, rotating magnet, and coil.

Technologically speaking, one of the oldest components on general aviation aircraft is the magneto, a technology that is more than 100 years old. The magneto is a self-contained generator of high voltage that provides ignition to an engine through spark p

Aircraft magnetos are self-contained ignition systems that generate electrical energy to create sparks in the engine's cylinders. Unlike automotive ignition systems, magnetos do not rely on the aircraft's battery or electrical system.

What is a magneto? A magneto is an electromechanical device that provides the electrical energy needed to ignite the fuel-air mixture in aircraft internal combustion engines. They are critical parts in the ignition system, and are mainly used in piston ai

Despite their simple appearance, magnetos are a key reason aircraft engines can run even if all electrical power is lost. Let’s break down what they are, how they work, and why they’re so important for safe flight.
