Turn Coordinator

Serials 0435 and subsequent with PFD: Turn Coordinator
function and roll data display is integrated into the PFD.
Serials with Avionics Configuration A - 0002 through 1601, 1603
through 1643 and 1645 through 1662 without PFD: The electric turn
coordinator displays roll information and provides roll data to the
integral System 30 autopilot. Roll rate is sensed by a single-gimbal,
electric-powered gyro and displayed on the face of the instrument. The
display consists of a symbolic airplane rotates to indicate turn rate and
a standard glass tube and ball inclinometer. Markings, labeled L & R,
indicate roll for a standard rate turn in the direction indicated.
Redundant circuits paralleled through diodes at the indicator supply
DC electrical power. 28 VDC for roll rate gyro operation is supplied
through the 2-amp TURN COORD #1 circuit breaker on the Essential
Bus and the 2-amp TURN COORD #2 circuit breaker on the Main Bus
2.
Serials with Avionics Configuration B - 0002 through 1601, 1603
through 1643 and 1645 through 1662 without PFD: The electric turn
coordinator, installed in the instrument panel, displays roll information
and provides roll data to the System 55X autopilot. The instrument and
power supplies are as described above.

Course Deviation Indicator

Serials with Avionics Configuration A - 0002 through 1601, 1603
through 1643 and 1645 through 1662 without PFD: The Course
Deviation Indicator (CDI) displays navigation information from GPS 2
(Garmin GNC 420). The CDI displays GPS track deviation on a single
