RCA15 Series electric directional gyro

The RCA15 Series electric directional gyro employs and electrically driven gyro motor and is a direct reading, azimuth indicator. Rotor run up time is 3 min. 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 cut out. Power failure flag drops into view when supply voltage is lost or has dropped below a level for proper operation of the gyro. Azimuth indication range 360°. Altitude operation -1,000 to 40,000 feet. Internal 3 phase inverter prodeces high starting torque and increases gyro roto speed. Internal lighting provides even light distribution at any intensity level. calibrated to an accuracy of 3° maximum drift error after 10 minutes of ±1.5° scorsby motion.

Meets of exceeds all requirements of FAA TSO C5c and Aeronautical Standard AS397.
Made in the USA
