SECTION 1. GENERAL
1.1 System Description
The G500H Flight Display System consists of a Primary Flight Display (PFD)
and Multi- Function Display (MFD) housed in a single Garmin Display Unit
(GDU 620), an Air Data Computer (GDC 74H ADC) and Attitude and Heading
Reference Systems (GRS 77H AHRS). The G500H interfaces with a Garmin
GNS 400W, 500W, or 480 series GPS/WAAS navigator and an audio panel.
Optionally, the G500H may interface with other systems installed in the
rotorcraft including a Garmin GTX330 transponder, TAS traffic system, GDL
69(A) satellite data link, video sources, radar altimeter and GSR 56 Iridium data
link.
The primary function of the PFD is to provide attitude, heading, air data and
navigation information (from GNS units) to the pilot. The primary function of
the MFD is to display supplemental data including mapping, terrain, video,
charts, and flight plan information.

the PFD is inoperative. These standby instruments should be included in the
