SECTION 9 AUTOMATIC FLIGHT CONTROL
SYSTEMS (OPTIONAL)
NOTE: The approved Pilot’s Operating Handbook (POH) always supersedes
the information in this Pilot’s Guide.
NOTE: Refer to the approved Pilot’s Operating Handbook (POH) for emergency
procedures.
NOTE: VOR, LOC, and GS modes are all GPS-aided. You must have a GPS
position and a valid navigation database to use VOR, LOC, or GS modes.
AFCS SYSTEM ARCHITECTURE
An Automatic Flight Control System (AFCS) is typically comprised of two major
components: A Flight Director (FD) and Autopilot servos. The Flight Director provides
pitch and roll commands to the autopilot servos. These pitch and rolls commands are
displayed on the PFD as Command Bars. When the Flight Director is active the pitch
and roll commands can be hand-flown by the pilot or when coupled with the autopilot,
the autopilot servos drive the flight controls to follow the commands issued by the
Flight Director. The Flight Director operates independently of the autopilot servos, but
in most cases the autopilot servos can not operate independent of the Flight Director.
On G3X installations that do not have a separate and independent Flight Director, the
Flight Director is always coupled to the autopilot.
AUTOPILOT AND YAW DAMPER OPERATION
The autopilot and optional yaw damper operate the flight control surface servos
to provide automatic flight control. The autopilot controls the aircraft pitch and roll
attitudes following commands received from the flight director. Pitch, Roll, and Yaw
(if installed) auto-trim provides trim commands to each servo to relieve any sustained
effort required by the servo(s). Autopilot operation is independent of the optional yaw
damper.
The optional yaw damper reduces Dutch roll tendencies, coordinates turns, and
provides a steady force to maintain directional trim. It can operate independently
