Figure 5-25. GFC Status Page
The GFC Status page displays the following status information regarding the GFC 700"
GIA STATUS
AP DISCONNECT:
Displays the condition of the AP DISC +28 VDC input to the GIAs and
servos, which is required for the Autopilot to operate. A green status indicator displays the AP
DISC switch is closed and the GFC 700 is actively receiving 28. volts. A black indicator box
indicates the GIAs and servos are no longer receiving the +28 VDC AP DISC power (switch
open or other fault).
MONITOR/CONTROL BOARD STATUS
Displays the condition of various monitor board components.
SERVO PROGRAM (1-3):
Servo program discretes are used to determine the HW strapping for
each
GSA to define the servo type. This information can be cross-referenced against the system
interconnects
to verify proper servo grounding.
AP DISCONNECT:
Same as GIA Status.
PFT:
Indicates whether the pre-flight test has passed or failed.
HIGH RES & HIGH RNG LOAD CELL CAL:
Displays the condition of the high resolution and
high range load cells on the monitor board. If box is black, this indicates a corrupt or missing
load cell calibration; return the servo to Garmin.
