GARMIN GFC700 AUTOPILOT (OPTIONAL)
There is no single LRU (Line Replaceable Units) with
the name “GFC 700”; rather “GFC 700” refers to an
integrated autopilot and flight director system, with
functions provided by multiple G1000 LRUs and ser-
vos. Refer to the G1000 Line Maintenance and Con-
figuration Manual (#190- 00303- 04 Rev F or later
FAA approved revision), Instructions for Continued
Airworthiness (#190- 00638- 002 Rev A) or later
FAA approved revisions and the Garmin G1000
Cockpit reference guide for more detailed informa-
tion.
The LRU’s used by Mooney (if installed)
- GDU 10XX Multi Function Display (MFD)
- GDU 10XX Primary Flight Display (PFD)
- GMA 1347(X) Audio Panel with Marker Beacon
Receiver
- GIA 63(X) Integrated Avionics Units (IAU)
- GDC 74(X) Air Data Computer (ADC)
- GEA 71 Engine/Airframe Unit
- GTX 33(X) Transponder
- GRS 77 Attitude and Heading Reference
System (AHRS)
- GMU 44 Magnetometer
- GDL 69(X) Satellite Data Link Receiver
- GSA 8(X) AFCS Servo Actuator
- GSM 86 Servo Gearbox
- GTP 59 Temperature Probe
The GFC 700 Autopilot is a two- axis fail- safe digital
flight control system that is integrated into the
G1000. It consists of the following components
which are added to the existing G1000 components:
- GSA 8(X) Servo Actuators (Roll, Pitch, Pitch
Trim)
- GSM 86 Servo Mounts (Roll, Pitch, Pitch Trim).
The following functions are provided by the GFC 700
in this installation:
- Flight Director
- Autopilot
- Manual Electric Pitch Trim
1. Flight Director -
The Flight Director operates
within GIA1 and uses air data, attitude, and naviga-
tion data to calculate commands for display to the pi-
lot and for the Autopilot. Flight Director command
bars and mode annunciations are sent to the PFD
through a high- speed Ethernet connection for dis-
play. The Flight Director operates independently of
the Autopilot and allows the pilot to hand- fly the air-
craft using command bar guidance if desired.
2. Autopilot: -
The Autopilot operates utilizing the
three GSA Servos. Flight Director data is processed
within the three servos and translated into aircraft
flight control surface commands. The Autopilot can-
not operate unless the Flight Director is engaged.
A. GDU 10XX PFD - Displays the Flight Director
command bars and the autopilot mode annunci-
ations.
B. GDU 10XX MFD - Provides controls for the
autopilot functions.
C. GIA 63 - Performs the calculations to display
the Flight Director command bars on the PFD and
sends control movement commands to the GSA 81
autopilot servos.
D. GSA 8(X) - Servo which actuates the control
surfaces based on commands received from the
GIA 63.
E. GSM 86 - Servo Mount connects to the GSA
81 Servo and contains slip clutches preset to a de-
fined calibration. The GSM 86 servo gear box clutch
is available in three torque sizes (short, medium, and
long), for each of the available mechanical interface
configurations (spiral, continuous, and sprocket,
etc.), with torque ranges defined by Table below:
1. Short Clutch: 15- 65 in- lbs

15% P/N
383- 00000- 15 thru 383- 00000- 65
2. Medium Clutch: 66- 120 in- lbs

15% P/N
383- 00000- 66 thru 383- 00001- 20
3. Long Clutch: 121- 180 in- lbs

15% P/N
383- 00001- 21 thru 383- 00001- 80
3. Configuration and Testing - After removal and
replacement, LRUs must be configured and tested,
refer to the G1000 Line Maintenance and Configura-
tion Manual (#190- 00303- 04 Rev F or later FAA ap-
proved revision) for more detailed information.
-CAUTION-
When removing and/or replacing any G1000
component, always ensure that aircraft power
is off. Unplug any auxiliary power supplies.
Before removing any G1000 LRU, it is re-
quired that the technician verify the LRU soft-
ware part number and version.
