AFCS OVERVIEW
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 Columbia 350/400 is distributed across the following Line
Replaceable Units (LRUs):
• GDU 1040 Primary Flight Display (PFD)
• GDU 1042 Multi-Function Display (MFD)
• GIA 63 Integrated Avionics Units (2)
• GSA 81 AFCS Servos (2)
• GTA 82 Pitch Trim Adapter (1)
• GSM 85 Servo Mounts (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) GIA 63. 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 and roll servos and the pitch trim adapter
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 adapter provides manual electric trim capability when the
autopilot is not engaged.
