What is the name of the mechanism used to transmit rudder angle information from the steering gear itself to the wheelhouse in the illustrated rudder angle indicator system? EL-0092

Correct Answer: Option B — synchronous transmission

Synchronous transmission systems, commonly utilizing selsyn or synchro devices, reliably replicate angular position over a distance. According to IEEE 45 standards, these systems use electrical rotor-stator coupling to seamlessly transmit mechanical rudder movement from the steering gear compartment to wheelhouse repeaters without requiring continuous physical linkage cables.
