1.2 LINE REPLACEAbLE UNITS
• GDU 1040 (3) – The GDU 1040 is configured as two Primary Flight Displays (PFD) and one Multi Function
Display (MFD). The displays communicate with each other through a High-Speed Data Bus (HSDB) Ethernet
connection. Each display is also paired with an Ethernet connection to an IAU.
• GMA 1347 (2) – The Audio Panel integrates navigation/communication radio (NAV/COM) digital audio,
intercom, and marker beacon controls, and is installed between the displays. This unit also provides manual
control of display reversionary mode (red
DISPLAY BACKUP Button; see Section 1.5, System Operation) and
communicates with both IAUs using an RS-232 digital interface.
• GIA 63W (2) – The Integrated Avionics Units (IAU) function as the main communications hub, linking all
LRUs with the PFD. Each IAU contains VHF COM/NAV/GS receivers and system integration microprocessors
and is paired with the on-side display via a HSDB connection. The IAUs are not paired together and do not
communicate with each other directly.
