    • Synchro Signal Amplifier (CRA-2-2A)

    The amplifier, located on the cockpit floor on the left side of the co-pilot’s seat, is a servo mechanism which repeats the aircraft heading derived by reference to the flux valve. The amplifier supplies magnetic heading information to the RMI, CDI and the BDHIs. The IND ØB circuit-breaker on the Radio Circuit-breaker Panel supplies the power that enables the magnetic heading to be displayed on the RMI, CDI and BDHIs.
