AUTOMATIC FLIGHT CONTROL SYSTEM
SECTION 7 AUTOMATIC FLIGHT CONTROL SYSTEM
7.1 AFCS OVERVIEW
NOTE: The approved Aircraft Flight Manual Supplement (AFMS) always supersedes the information in this
guide.
NOTE: A failure of the primary (#1) GIA 63 Integrated Avionics 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
avionics architecture. Refer to Figure 1-1 in the System Overview for a block diagram supporting this system
description. GFC 700 AFCS functionality in the Beechcraft A36/G36 is distributed across the following Line
Replaceable Units (LRUs):
• GDU 1040 Primary Flight Display (PFD)
• GSA 81 AFCS Servos - 4
• GDU 1043 Multi-Function Display (MFD)
• GSM 85 Servo Mounts - 4
• GIA 63 Integrated Avionics Units (IAU) - 2
The GFC 700 AFCS performs 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, pitch trim, and roll servos and provides servo
monitoring and automatic flight control in response to flight director steering commands, AHRS attitude and
rate information, and airspeed.
• Yaw Damper (YD) — The yaw servo is self-monitoring and provides Dutch roll damping and turn coordination
in response to yaw rate, roll angle, vertical acceleration, and airspeed.
• Manual Electric Trim (MET) — The pitch trim servo provides manual electric trim capability when the
autopilot is not engaged.
