7.1 AFCS OVERVIEW
NOTE:
The approved current pertinent flight manual always supersedes this Pilot’s Guide.
The Garmin AFCS is a digital Automatic Flight Control System (AFCS), fully integrated within the system
avionics architecture. The System Overview section provides a block diagram to support this system description.
The Garmin AFCS can be divided into these main operating functions:
•
Flight Director (FD)
— Flight director operation takes place within the GIA #1 (Integrated Avionics Unit).
Flight director commands are displayed on the PFD. The flight director provides:
-
Command Bars showing pitch/roll guidance.
-
Vertical/lateral mode selection and processing.
-
Autopilot communication.
•
Autopilot (AP)
— Autopilot operation occurs within the pitch, roll, and pitch trim servos. It also provides
servo monitoring and automatic flight control in response to flight director steering commands, Attitude and
Heading Reference System (AHRS) attitude, rate information, and airspeed.
•
Manual Electric Trim (MET)
— The pitch trim adapter provides manual electric trim capability when the
autopilot is not engaged.
