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 or GIA 64Es 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 81 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.

Underspeed Protection:

The optional Underspeed Protection (USP) system is available when the 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 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.

190-00682-N1

2.1.2 GDU 1050A PFD (2) & GDU 1550 MFD

Two Garmin GDU 1050A displays and one GDU 1550 display are installed in the King Air

instrument panel. The GDU 1050A units, 10.4 inch LCD displays with 1024x768 resolution, are

configured as PFD 1 and PFD 2; the GDU 1550 unit, a 15 inch LCD display with 1400 x1050

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 or GMA 1360D 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

475 is installed in the pedestal. The GCU 475 provides the control interface for the MFD.

The GDU 1550 communicates with the GDU 1050A units, GDL 69A /GDL69 SXM datalink,

GWX68, GWX 70, or GWX 75 weather radar through a high-speed data bus (HSDB) Ethernet

connection. The GDU 1550 communicates with the GCU 475 via RS-232 digital interface.

The GDU 1050A units communicate with each other and the GIA 63W or GIA 64E units through

a high-speed data bus (HSDB) Ethernet connection.

Electrical power to PFD 1, MFD, and PFD 2 is provided by the triple-fed bus. The triple-fed bus

is powered by the battery and both generator buses. Additionally, a secondary power source is

provided to PFD 1 by the center bus, which is fed by both generator buses and the battery.

Therefore, the displays 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 installed behind the panel for PFD and MFD cooling.

2.1.3 Flight Stream 510

The Flight Stream™ 510 (FS 510) is a Wi-Fi/Bluetooth capable multi-media card (MMC) that is

installed in the bottom SD slot of the MFD. It sends position, velocity, time, attitude, heading,

and flight plan transfer to mobile devices via Bluetooth. It is also capable of sending FIS-B, TIS-

B traffic, Sirius XM audio control, and Sirius XM weather data. The FS 510 can also interface

with a mobile device via Wi-Fi for the purposes of updating databases used by the GDU(s).

Bluetooth and Wi-Fi are mutually exclusive with only one interface functional at a time.

Connecting via Wi-Fi requires a pilot-configurable Wi-Fi Protected Access WPA2 security

password. By updating databases wirelessly, new databases may be transferred to the G1000

system without taking the data card out of the aircraft.

Figure 2-2, Flight Stream 510

2.1.4 GMA 1347D or GMA 1360D Audio Panel (2)

The Garmin GMA 1347D or GMA 1360D Audio Panel integrates NAV/COM digital audio,

intercom system and marker beacon controls. The C90 Series installation includes two GMA

1347D or GMA 1360D panels. The GMA 1347D or GMA 1360D panels provide control of all

cockpit intercom/mic systems as well as NAV/COM/ILS audio. The units also provide display

reversion mode control through a large red button. Warning and alert audio received by the

GMA 1347Ds or GMA 1360Ds is processed by and received from the GIA 63W or GIA 64E

Integrated Avionics Units (IAUs). Electrical power to GMA 1 and GMA 2 is provided by the

Avionics Bus. These units will operate after selecting Avionics Master on. The GMA 1347D

or GMA 1360D unit interface with the existing marker beacon antenna, as well as existing mic

and phone jacks and oxygen mask mic.
