Overview

An absolute treasure trove of information about the Bendix and Slick magnetos used on virtually all piston aircraft engines. The book covers everything you could possibly want to know about how your aircraft ignition system works.

The book will make you knowledgeable about the functions of the magneto coil, rotor, capacitor, points, P-lead, impulse coupling, and ignition harness. Learn what "E" gap means and why it's so important. The difference between internal magneto timing and magneto-to-engine timing. What "bumping" the magneto means. How altitude and temperature affect the magneto. What the voltage and energy requirements are for reliable ignition, and how spark plug leads and radio noise filters may reduce magneto output.

Schwaner reviews all of the different models of Bendix and Slick magnetos, and describes their strengths and weaknesses. He shows you how to choose the best mag for your type of flying: which mag is best for high altitude, ease of maintenance, low radio noise. The pros and cons of the impulse coupling magneto versus the retard breaker ("shower of sparks") magneto. He explains what to look for during the preflight mag check, and how to troubleshoot starting problems and engine roughness.About a third of the book is devoted to topics of specific interest to the A&P mechanic or maintenance-involved owner. Recommendations for preventative magneto maintenance are set forth in great detail. Listings and discussions of ADs and service bulletins for all Bendix and Slick models are included.

The book is profusely illustrated with photographs, drawings, graphs, and tables. You'll want to add this great little book to your maintenance library.

THE MAGNETO IGNITION SYSTEM

July 21, 2021

As a student in aircraft maintenance, I thought this would be a good addition to my library. Some interesting things in there but I was hoping for a little more. Good place to start though.

This is a good book on the TECHNICAL aspects of how magnetos work (lots of theory of magnetism etc.) and worth having if you are looking for that kind of info. If however you are looking for step-by-step instructions on how to set the e-gap or how to time the magneto to the engine this is not the book for you. I found the organization somewhat lacking - rambles between subjects to some degree but still a good reference book to have in my library.
