Ground Lesson 13
GFC 700 AUTOMATIC FLIGHT CONTROL SYSTEM (AFCS)
Objectives
Upon completion of this lesson, the pilot should be able to understand the operation of the
Garmin Automatic Flight Control System (AFCS) and use the autopilot throughout various
phases of flight.
Resources
• GIFD Pilot’s Guide
Exercise 13.1: Flight Director and Autopilot Operation
1.
List all parts (LRUs) associated with the GFC 700 in the aircraft being flown.
• GDU 1XXX Primary Flight Display (PFD), Multi Function Display (MFD)
• GIA 63 Integrated Avionics Unit
• GSA 8X Servos
• GSM 85 Servo Mounts
• GTA 82 Trim Adapter (selected installations)
• GMC 71X AFCS Control Unit (selected installations)
2.
Where are the AFCS controls located in the cockpit?
Generally, the MFD has dedicated AFCS keys located on the lower left side of the bezel.
Depending on the aircraft type, autopilot controls may be on the remotely mounted GMC
AFCS Control Unit.
3.
Where are flight director mode annunciations displayed?
Describe the annunciation colors.
The AFCS Status Box is displayed towards the top of the PFD, just below the Navigation
Status Box.
Active modes are displayed in green; armed modes are displayed in white.
Roll modes are on the left side and pitch modes are on the right, and autopilot/yaw
damper engagement status is shown in the center.
4.
List any flight director pitch and roll limitations.
Pitch and roll limitations vary from aircraft to aircraft.
Consult the approved Aircraft
Flight Manual (AFM) or Aircraft Flight Manual Supplement (AFMS) and Pilot’s Guide for
specific aircraft limitations.
5.
Describe Flight Level Change Mode (FLC).
When the
FLC
Key is pressed, FLC Mode is activated and the current airspeed is
maintained as the Airspeed Reference while the aircraft is climbing/descending toward the
Selected Altitude.
It is important to adjust the engine power to allow the autopilot to
maintain the aircraft at the pitch attitude that corresponds to the Airspeed Reference and
desired flight profile.
6.
Describe the function of the Control Wheel Steering (
CWS
) Button.
The
CWS
Button synchronizes the flight director’s command bars to the current aircraft
attitude (refer to the Pilot’s Guide AFCS Section for CWS behavior in specific modes).
