Standard Electric Turn Coordinator. Multi-Volt 11-30VDC

This instrument is used in many production aircraft. It contains an electrically driven gyroscope supported in a gimbal inclined to the horizon so that the instrument senses roll as well as yaw. The RCA82A series is an all volt instrument that works from 11 – 30VDC. The movement is presented by an airplane symbol banking on a fixed horizon with a power warning flag.
