1.1.2 GDU 620
The GDU 620 has dual VGA (640 x 480 pixels) 6.5 inch LCD displays. The
right side of the GDU is a PFD and the left side is the MFD. In some models or
installations, the PFD and MFD and their controls are switched to the other side.
The MFD shows a moving map, flight plan, weather, and other supplemental
data. The PFD shows primary flight information, in place of traditional pitot-
static and gyroscopic systems and also provides an HSI for navigation.

1.1.3 GDC 74H
The GDC 74H Air Data Computer (ADC) compiles information from the
pitot/static system and an Outside Air Temperature (OAT) sensor. The GDC 74H
provides pressure altitude, airspeed, vertical speed, and OAT information to the
G500H system. The GDC 74H communicates with the GDU 620 and GRS 77H
using an ARINC 429 digital interface.
