2.1 Equipment Descriptions
2.1.1 GDU 1040A PFD (2) & GDU 1500 MFD
Two Garmin GDU 1040A displays and one GDU 1500 display are installed in the King Air instrument
panel. The GDU 1040A units, 10.4 inch LCD displays with 1024x768 resolution, are configured as PFD 1
and PFD 2; the GDU 1500 unit, a 15 inch LCD display with 1024x768 resolution, is configured as a MFD.
All displays provide control and display of nearly all functions of the G1000 integrated cockpit system. The
PFD displays are located on either side of the MFD, with the stand-by instruments located between the
Pilot’s PFD (PFD 1) and the MFD. GMA 1347D Audio Panels are located outboard of each PFD.
Additionally, a GMC 710 AFCS Controller is located in the upper instrument panel, above the MFD, and a
GCU 477 is installed in the pedestal. The GCU 477 provides the control interface for the MFD.
The GDU 1500 communicates with the GDU 1040A units, GDL 69A datalink, GWX68 weather radar,
optional GDL59 wi-fi datalink and optional GTS 8XX traffic through a high-speed data bus (HSDB)
Ethernet connection. The GDU 1500 communicates with the GCU 477 via RS-232 digital interface.
The GDU 1040A units communicate with each other and the GIA 63W units through a high-speed data bus
(HSDB) Ethernet connection.
PFD 1 receives primary electrical power from the new Essential Bus and secondary electrical power from
Dual Fed Bus No. 1. PFD 2 receives electrical power from Dual Fed Bus No. 2. Electrical power to the
MFD is also provided by the Essential Bus. The displays will power-up immediately with external or
aircraft power or battery operation.
All displays are installed in the King Air panel using ¼-turn fasteners. Three CDU cooling fans are also
installed behind the panel for PFD and MFD cooling.
