The unit installed on the left/pilot side is designated as PFD1, and the one installed on the right/copilot side
is designated as PFD2. These units communicate with each other, the MFD, and with the on-side GIA 63W
Integrated Avionics Unit through a High-Speed Data Bus (HSDB) connection.
• GDU 1500 – Features a 15-inch LCD with 1024 x 768 resolution and is configured as an MFD. This unit is
linked to both PFDs via HSDB connection.
• GIA 63W – Functions as the main communication hub, linking all LRUs with the on-side PFD. Each GIA 63W
contains a GPS SBAS receiver, VHF COM/NAV/GS receivers, a flight director (FD) and system integration
microprocessors. Each GIA 63W is paired with the on-side PFD via HSDB connection. The GIA 63Ws are not
