The statement concerning most light sport aircraft engines having breaker-less magneto capacitor discharge systems is true because these systems are designed to operate without the mechanical breaker points typically found in traditional ignition systems. Breaker-less ignition reduces maintenance needs and provides more reliable spark delivery, which is essential for ensuring the engine runs smoothly and efficiently. This type of ignition system often features electronic components that enhance performance and reliability while simplifying design and upkeep.

Additionally, the evolution of aircraft ignition systems towards breaker-less designs reflects advancements in technology aimed at improving safety and reducing pilot workload. This shift is especially relevant in light sport aircraft, which often prioritize ease of use and maintenance. Consequently, most modern light sport aircraft engines utilize this advanced ignition technology to achieve optimal performance and reliability.
