What is the primary function of a propeller synchronization system?

The primary function of a propeller synchronization system is to set propellers to the same RPM. This system is crucial in multi-engine aircraft, where variations in propeller speeds can lead to asymmetric thrust, which can adversely affect the aircraft's handling and performance. By synchronizing the RPMs of the propellers, the system helps ensure that the aircraft operates smoothly and efficiently.

When propellers are synchronized, it reduces cockpit workload for the pilots and enhances overall performance, especially in conditions where engine power management is critical. Additionally, synchronized operation can minimize noise levels and vibrations experienced during flight, further improving passenger comfort and safety.

Other functions related to engine operation, such as adjusting fuel flow or controlling pitch, are separate systems and do not specifically pertain to the synchronization of RPM across multiple propellers.
