How many ignitors does the engine ignition system utilize?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The engine ignition system of the TH-73A helicopter utilizes two ignitors to ensure reliable and effective engine starts. This dual ignitor design significantly enhances ignition reliability, as having two ignitors provides a backup in the event that one fails. This redundancy is crucial in aviation, where the dependability of all systems is essential for safety and operational effectiveness. By employing two ignitors, the system can ensure a more robust ignition process, accommodating various operational conditions and minimizing the risk of failure during critical phases such as startup and operation.
