The RCA15 Series electric directional gyro employs an electrically driven gyro motor and is a direct reading, azimuth indicator. Rotor run up time is 3 minutes. They have a built in inverter which converts aircraft DC power to the required AC voltage and frequency. May be used in both fixed wing and rotor wing aircraft and is easily installed in standard 3 1/8” panel cutout. Power failure flag drops into view when supply voltage is lost or has dropped below proper operation voltage of the gyro. * Azimuth indication range: 360°.* Altitude operation: 1,000 to 40,000 feet. * Internal 3 phase inverter produces high starting torque and increases gyro rotor speed. Calibrated to an accuracy of 3° maximum drift error after 10 minutes of +/- 1.5° Scorsby motion.
