2.3 Control/Operation Information

2.3.1 G600 System

The GDU 620, GRS 77, GMU 44, and GDC 74A are powered by Main Bus 2 which is normally energized

with battery, generator, or external power applied to the aircraft. The GAD 43 is powered by Avionics Bus

1 which is normally controlled by the Avionics Bus 1 master switch. The LRUs do not have individual

power switches and are powered when the bus is energized and the circuit breakers are closed. The

following circuit breakers provide power to the individual LRUs:

• PFD: GDU 620

• AHRS 1: GRS 77 #1 and GMU 44 #1

• AHRS 2: GRS 77 #2 and GMU 44 #2

• ADC: GDC 74A

• GAD: GAD 43

The GDU 620 has a PFD (left) and MFD (right) display and front panel controls for performing all G600

normal and configuration operations. Knobs at the lower left and right corners are used for selecting and

entering data on each screen. The function of the soft keys along the bottom of the display is depicted by

the text above the key. There are dedicated ENT, CLR, and MENU keys on the right side of the unit.

Turning the PFD knob adjusts the values for the mode selected by the PFD bezel keys, such as, Heading

(HDG), Course (CRS), Altitude (ALT), Vertical Speed (V/S), and Barometric Setting (BARO). The values

are shown in a window to the left of the HSI. Pressing the PFD knob reverts to the default value of the

selected mode.

The Small (Inner) MFD Knob selects a specific page within a page group. Pressing the small MFD knob

turns the selection cursor ON and OFF. When the cursor is ON, data may be entered in the applicable

window by turning the small and large MFD knobs. In this case, the large MFD knob moves the cursor on

the page and the small MFD knob selects individual characters or values for the highlighted cursor

location. The Large (Outer) MFD Knob selects the MFD page group. When the cursor is ON, the large

MFD knob moves the cursor to highlight available fields.

The G600 system starts in normal mode when power is applied to the LRUs. After completing the self-

test, the database confirmation page is displayed. Invalid or expired databases are displayed in yellow.

Press ENT to proceed to normal mode. Normal mode consists of a Primary Flight Display (PFD) on the

left screen and a Multifunction Display (MFD) on the right screen. The AHRS alignment should complete

within one minute and attitude should be displayed on the PFD. System alerts are accessible via an

“ALERTS” softkey at the lower right of the MFD. During normal system operation with all aircraft systems

and avionics powered there should not be any red Xs or system alerts on the GDU 620.

To enter into Configuration Mode for the G600 system, verify that the GDU 620 is off and the Installer

Unlock Card, P/N 010-00769-60 is installed in the bottom card slot of the GDU 620. Apply power to the

GDU 620 while holding the ENT key. Release the ENT key when “INITIALIZING SYSTEM” appears in

the upper left corner of the display.

Refer to the appropriate Modification Summary, Section 4, for further Configuration instructions.

2.3.2 GNS 530W/430W

GNS 530W: The GNS 530W is powered by Avionics Bus 1 which is normally controlled by the Avionics

Bus 1 master switch. The GNS 530W also contains a power switch which is controlled by the COM

volume rotary knob near the upper left corner. COM 1 and NAV 1 circuit breakers on Avionics Bus 1

supply power to the GNS 530W.

GNS 430W: The GNS 430W is powered by Avionics Bus 2 which is normally controlled by the Avionics

Bus 2 master switch. The GNS 430W also contains a power switch which is controlled by the COM
