RCA82A-11 3" Turn Coordinator, Unlighted

RCA82A-11 3" Turn Coordinator, Unlighted 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/83A 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. Contains an electrically driven gyroscope All volt instrument works from 11 to 30 volts dc Fine quality instrument by RC Allen and used in many production aircraft. Incorporates an electrical Gyro Turn Indicator with an inclinometer. The inclinometer, by movement of a ball in relation to the lubber lines, indicates the slip angle of aircraft while in a turn. The airplane on the dial rotates with reference to the indices. A power failure flag drops into view whenever the supply voltage is lost or when voltage has dropped below a level acceptable for proper operation of the gyro.
