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 Fuel & Fuel Metering Systems: How Aircraft Engines Get the Right Fuel at the Right Time An aircraft engine can have perfect compression, a strong ignition system, and plenty of airflow, but none of that matters if the engine does not receive the correct amount of fuel at the correct time. That is the job of the aircraft’s fuel and fuel metering system. At first glance, the purpose of a fuel system seems simple: move fuel from the aircraft’s fuel tanks to the engine. In reality, the system has to do much more than simply deliver fuel. ...

Understanding Turbine Engines A Complete FAA A&P Powerplant Study Guide Based on concepts from the FAA Aviation Maintenance Technician Handbook – Powerplant (FAA-H-8083-32). Introduction Gas turbine engines are the primary powerplants used in modern commercial, military, and many business aircraft. Their high power-to-weight ratio, reliability, and ability to operate efficiently at high altitudes make them ideal for aviation. Unlike reciprocating engines, turbine engines operate on the Brayton Cycle, where air flows continuously through the engine rather than being drawn into individual cylinders. ...

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. ...
