2.1.1.1 Displays
The foundation of a G3X system is one or more GDU display units. A GDU display is configured via
wiring connections as either a primary flight display (PFD) or multi-function display (MFD), with options
for arranging display layouts and combining different types of data on a single display. In the event that
power is removed from a GDU display, important flight data can still be accessed on the remaining
display(s).
A legacy (non-Touch) G3X system can have between one and three GDU 37X displays.

information, refer to
A G3X Touch system can have between one and four GDU 4XX displays, with any combination of 10.6”
(GDU 46X) and 7” (GDU 45X or GDU 470) display sizes. Figure 2-2 shows some of the various interface
options for a GDU 4XX-based system. For GDU 4XX installation information, refer to
