2 SYSTEM DESCRIPTION

2.1 Equipment Descriptions

2.1.1 GFC 700 Operation

The GFC 700 is a fail-passive digital flight control system composed of multiple G1000 LRUs and
servos. The following functions are provided by the GFC 700 in this installation:

• Flight Director

• Autopilot

• Pitch Trim

• Yaw Damper

• Electronic Stability and Protection (optional)

Flight Director:

The Flight Directors operate within the GIA 63Ws and use data from the G1000 system, including air,
attitude and flight data, to calculate commands for display to the pilot and for the Autopilot. Flight
director command bars and mode annunciations are sent to the PFDs through a high-speed Ethernet
connection for display to the pilot and copilot. The flight directors operate independently of the autopilot
and allow the pilot to hand-fly the command bars, if desired. The GMC 710 allows the pilot to switch the
active director between flight director #1 (GIA1) and flight director #2 (GIA2).

Autopilot:

The autopilot operates within one high-speed GSA 80 servo (pitch trim) and three GSA 80 servos (pitch,
roll and yaw). Flight director data is processed within the servos and turned into aircraft flight control
surface commands. The autopilot cannot operate unless the flight director is engaged.

Manual Electric Trim:

When the autopilot is not engaged, the pitch trim servo may be used to provide a Manual Electric Pitch
Trim (MEPT) function. This allows the pilot or co-pilot to adjust pitch trim from the PITCH TRIM
switch on the control wheel in lieu of using the elevator trim wheel. Trim speeds are scheduled to provide
easier control over a wide speed or configuration range. The PITCH TRIM switch is split into two halves.
The left half arms MEPT. The right half controls direction. Both halves must be actuated at the same time
to command the pitch trim servo to operate. If only one half of the PITCH TRIM switch is actuated for
more than 3 seconds, a red PTRM message will appear on the PFDs.

Yaw Damper:

The yaw damper reduces Dutch roll tendencies and coordinates turns. It can operate independently of the
autopilot and may be used during normal hand-flight maneuvers.

Electronic Stability and Protection:

Electronic Stability and Protection (ESP) is an optional function that is intended to assist the pilot in
maintaining the airplane in a safe flight condition within the aircraft flight envelope. This envelope is
defined by pitch, roll, and airspeed. This feature is only active when in flight and the autopilot is off.
There are two versions of the ESP option available: ESP with Angle of Attack (AOA) modes and ESP
without Angle of Attack (AOA) modes. The ESP option with AOA modes requires a new lift computer.
The ESP option without AOA modes uses the existing lift computer.

Underspeed Protection:

Underspeed Protection (USP) is available when the optional ESP system is installed and the autopilot is
on. It is designed to discourage aircraft operation below minimum established airspeeds. When the
aircraft decelerates to stall warning, the autopilot will provide input causing the aircraft to pitch down and

G1000 / GFC 700 System Maintenance Manual - 300/B300 Series King Air Page 2-1
190-00716-01 Revision 4

wings to level. The pitch down force will continue until the aircraft reaches a pitch attitude at which IAS
equals the IAS at which stall warning turns off, plus two knots.

2.1.2 GDU 1040A PFD (2) & GDU 1500 MFD

Two Garmin GDU 1040A displays and one GDU 1500 display are installed in the King Air instrument
panel. The GDU 1040A units, 10.4 inch LCD displays with 1024x768 resolution, are configured as PFD
1 and PFD 2; the GDU 1500 unit, a 15 inch LCD display with 1024x768 resolution, is configured as a
MFD. All displays provide control and display of nearly all functions of the G1000 integrated cockpit
system. The PFD displays are located on either side of the MFD, with the stand-by instruments located
between the Pilot’s PFD (PFD 1) and the MFD. GMA 1347D Audio Panels are located outboard of each
PFD. Additionally, a GMC 710 AFCS Controller is located in the upper instrument panel, above the
MFD, and a GCU 477 is installed in the pedestal. The GCU 477 provides the control interface for the
MFD.

The GDU 1500 communicates with the GDU 1040A units, GDL 69A datalink, GWX68 or GWX70
weather radar, optional GSD41 data concentrator, optional GDL59 wi-fi datalink and optional GTS
820/850 or GTS Processor traffic through a high-speed data bus (HSDB) Ethernet connection. The GDU
1500 communicates with the GCU 477 via RS-232 digital interface.

The GDU 1040A units communicate with each other and the GIA 63W units through a high-speed data
bus (HSDB) Ethernet connection.

PFD 1 receives primary electrical power from No. 1 Triple Fed Bus and secondary electrical power from
Center Bus. PFD 2 receives electrical power from No. 3 Triple Fed Bus. Electrical power to the MFD is
provided by No. 2 Triple Fed Bus. The displays will power-up immediately with external or aircraft
power or battery operation.

All displays are installed in the King Air panel using ¼-turn fasteners. Three CDU cooling fans are also
