roll information and provides roll data to the System 55X autopilot. The
instrument and power supplies are as described above.
Directional Gyro
Avionics Configuration 2.0:
The airplane is equipped with a directional gyro in the standard
configuration. If a directional gyro is not installed the airplane will be
equipped with an HSI.
The directional gyro, in the left instrument panel, displays airplane
heading by rotating a compass dial in relation to a fixed simulated
airplane image and lubber line. The compass dial rotates counter
clockwise for right turns. The compass dial should be set in agreement
with the magnetic compass just prior to takeoff. As the gyro will
precess slightly over a period of time, the directional gyro compass
dial should be readjusted occasionally on extended flights. 28 VDC for
lighting is supplied through the 2-amp INST LIGHTS circuit breaker on
Main Bus 1.
To adjust compass card:
1. Push and hold knob at lower left corner of instrument.
2. While holding knob in, rotate knob to adjust gyro compass dial
with current magnetic heading.
3. Release knob.
