What is a synchro used for?

• A. A device used to transmit indications of angular movement or position from one location to another.
• B. A gauge that measures airspeed.
• C. A mechanism that automatically stabilizes the aircraft's heading.
• D. A display showing navigation data.

Answer: (D)

Synchro systems are used to convey angular position information from one location to another, so the cockpit indicator can show that data. In practice, the transmitter encodes the angle as an electrical signal and the receiver reproduces it at the display, driving an instrument that presents navigation data to the pilot. That makes a display showing navigation data the most representative description of what a synchro accomplishes in the cockpit.
