2.2 LRU Descriptions
2.2.1 GDU 1050 Display Unit
The three GDU (Garmin Display Unit) 1050s are LCD screens with 1024 x 786
resolution. The GDU 1050 displays are installed in the Kodiak instrument panel. Two
units are configured as PFD 1 and PFD 2, the third is configured as an MFD. All displays
provide control and display of nearly all functions of the system. The PFD displays are
located on either side of the MFD, with the stand-by instruments located to the left of
PFD1. The two GMA 1360D Audio Panels are located inboard of each PFD. Additionally,
a GMC 710 AFCS Controller is on the center instrument panel.
The GDL 69A SXM datalink and the GWX weather radars are connected to the MFD
through a high-speed data bus (HSDB) Ethernet connection. The displays communicate
with each other and the GIA units through a HSDB Ethernet connection as well. PFD1
communicates with the GTS 800 through a HSDB. The Garmin GTX 345R transponder
communicates with the GIA through an RS-232 interface.
2.2.2 Flight Stream 510 Wireless Transceiver
The Flight Stream 510 is a Wi-Fi and Bluetooth capable multimedia card installed in the
bottom SD card slot of an MFD. It sends position, velocity, time, attitude, heading, FIS-B,
TIS-B traffic, Sirius XM audio control, Sirius XM weather data, and flight plan transfer to
mobile devices by Bluetooth. The Flight Stream 510 can also interface with a mobile
device using Wi-Fi pairing for the purpose of updating databases used by the GDUs.
Bluetooth and Wi-Fi are mutually exclusive, with only one interface functional at a time.
Connecting through Wi-Fi requires a pilot-configurable Wi-Fi Protected Access WPA2
security password. By updating databases wirelessly, new databases can be transferred
to the G1000 NXi system without taking the data card out of the aircraft.
2.2.3 GMA 1347 Audio Panel
The GMA 1347 is a vertically oriented panel mounted audio control and marker beacon
system. The system delivers reliability and versatility for all audio controlling functions.
LED-illuminated push buttons and logical panel layout allow audio selection of NAV,
COM, DME, ADF, MKR, TEL, AUX, and automatic warning audio in voice or tone
annunciation. LED brightness is adjusted to a level appropriate for ambient cockpit light
conditions automatically by the GDU or manually with radio lighting controls, depending
upon installation connections. A failsafe circuit connects the pilot's headset and
microphone directly to COM 1 in case power is interrupted or the unit is turned off.
