CHAPTER 31

Section 31-00-00 Instruments

1. Description and Operation

The Garmin G500H Flight Display System consists of an instrument panel mounted GDU 620 display and

remote mounted LRUs which provide data to the display. The GDU 620 provides controls for the

G500H system and a PFD and MFD in the pilot’s primary field of view. The remote mounted LRUs

include one GRS 77H AHRS, one GMU 44 Magnetometer, one GDC 74H ADC, and one GTP 59 OAT

probe.

The G500H system depends on electrical power to function. The Garmin Display Unit (GDU), Attitude

and Heading Reference System (AHRS), and Air Data Computer (ADC) are connected to the aircraft

main bus.

The major components of the G500H are circuit breaker protected with push-pull type circuit breakers

available to the pilot. These breakers are located in the pedestal circuit breaker panel (30 α) and are

labeled as shown in Table 31-01.

2. Removal and Installation

If any G500H LRUs are removed and reinstalled or a new unit is installed, verify that the LRU unit

power-up self-test sequence is successfully completed and no failure messages are annunciated on the

GDU 620 display.

If any work has been done on the rotorcraft that could affect the system wiring or any interconnected

equipment, verify the G500H system unit power-up self-test sequence is successfully completed and no

failure messages are annunciated on the GDU 620 display.

Whenever removing or installing units, remove power from the LRU by removing aircraft power or

opening the LRU circuit breaker.
