An engine synchronization system automatically synchronizes the engines to reduce noise level and enhance passenger comfort.

• A. Not installed
• B. Only during takeoff
• C. False
• D. True.

Answer: (D)

Engine synchronization keeps the two engines’ speeds in alignment, matching their RPM and phase so they run as a pair rather than fighting each other. In the Beechjet 400A CTSys, the synchronizer constantly compares the engines’ RPM and makes small adjustments to one engine’s fuel or reference signal to bring both sides into lockstep. This smooths out pulsations and reduces the noise and vibration that passengers feel in the cabin, delivering a more comfortable ride. Since the system is designed to operate automatically whenever engaged, the statement that it synchronizes automatically to lower noise and improve comfort is accurate. It isn’t restricted to takeoff, and it isn’t correct to say it isn’t installed or that the concept is false.
