Development of a Dual Ignition System for General Aircraft

A new dual magneto has been developed for use on engines in business and small military aircraft. This ignition system represents a considerable advance in the areas of weight saving, ease of installation, maintainability, and synchronization of the two sparks in each cylinder. This paper describes the reasons for its development, design details, and the test program followed in its development. It includes a discussion of the problems encountered during testing and the natures of their solutions.
