AUTOMATIC FLIGHT CONTROL SYSTEM
SECTION 7 AUTOMATIC FLIGHT CONTROL SYSTEM
NOTE: The approved Pilot’s Operating Handbook (POH) always supersedes this Pilot’s Guide.
NOTE: The GFC 700 AFCS is not available for the Cessna 172R or 172S.
NOTE: A failure of the primary (#1) GIA 63 IntegratedAvionics Unit (IAU) results in loss of the flight director. Any IAU failure results in loss of the autopilot and manual electric trim.
The GFC 700 is a digital Automatic Flight Control System (AFCS), fully integrated within the G1000 System avionicsarchitecture. TheSystemOverviewsectionprovidesablockdiagramtosupportthissystemdescription. GFC 700 AFCS functionality in Cessna Nav III aircraft is distributed across the following Line Replaceable Units (LRUs):
• GDU 1044B |
Primary Flight Display (PFD) |
• GSA 81 AFCS Servo (3) |
• GDU 1044B |
Multi-Function Display (MFD) |
• GSM 85 Servo Mounts (3) |
•GIA 63/63W Integrated Avionics Units (2)
The GFC 700 AFCS can be divided into these main operating functions:
•Flight Director (FD) — Flight director operation takes place within the primary (#1) IAU. Flight director commands are displayed on the PFD.
The flight director provides:
–Command Bars showing pitch/roll guidance
–Pitch/roll mode selection and processing
–Autopilot communication
•Autopilot (AP) — Autopilot operation occurs within the pitch, roll, and pitch trim servo and provides servo monitoring and automatic flight control in response to flight director steering commands, AHRS attitude and rate information, and airspeed.
•Manual Electric Trim (MET) — The pitch trim servo provides manual electric trim capability when the autopilot is not engaged.

AUTOMATIC FLIGHT CONTROL SYSTEM
The following AFCS controls are located in the cockpit separately from the MFD:
AP DISC Switch
(Autopilot Disconnect)
CWS Button
(Control Wheel Steering)
GA Switch (Go Around)
MET Switch
(Manual Electric Trim)
Disengages the autopilot and flight director; interrupts pitch trim operation
This switch may be used to acknowledge an autopilot disconnect and mute the associated aural tone.
The red AP DISC Switch is located forward of the MET Switch on the pilot’s control wheel left grip.
While pressed, allows manual control of the aircraft while the autopilot is engaged and synchronizes the flight director’s Command Bars with the current aircraft pitch (if not in a Vertical Navigation, Glideslope, or Glidepath Mode) and roll (if in Roll Hold Mode)
Upon release of the CWS Button, the flight director may establish new reference points, depending on the current pitch and roll modes. CWS operation details are discussed in the flight director modes section.
The CWS Button is located on the top of the pilot’s control wheel right grip. Disengages the autopilot and selects flight director Go Around Mode
This switch also activates the missed approach when the selected navigation source is GPS or when the navigation source is VOR/LOC and a valid frequency has been tuned.
The GA Switch is located on the instrument panel above the throttle. Used to command manual electric trim
This composite switch is split into left and right sides. The left switch is the ARM contact and the right switch controls the DN (forward) and UP (rearward) contacts. The MET ARM Switch can be used to disengage the autopilot and to acknowledge an autopilot disconnect alert and mute the associated aural tone.
Manual trim commands are generated only when both sides of the switch are operated simultaneously. If either side of the switch is active separately for more than three seconds, MET function is disabled and ‘PTRM’ is displayed as the AFCS Status Annunciation on the PFD. The function remains disabled until both sides of the switch are inactivated.
The MET Switch is located on the pilot’s control wheel left grip.
