SECTION 7 AUTOMATIC FLIGHT CONTROL SYSTEM

7.1 AFCS OVERVIEW

NOTE: The Aircraft Flight Manual (AFM) 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 AFCS. 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 Mooney M20M/M20R/M20TN aircraft 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 (3)

• GSM 85 Servo Mounts (3)

The GFC 700 AFCS performs these main operating functions:

• Flight Director (FD) — Flight director operation takes place within the primary (#1) GIA 63 Integrated

Avionics Unit (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 servos 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.
