Product Review

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.
