1.1.1. Primary Flight Display Unit (PFD)
The Primary Flight Display Unit (PFD) is a digital system that consists of a high
resolution, six-inch diagonal color LCD display, user controls, photocell, and microSD
data card slot. The three-inch diameter, four-inch deep can on the back of the display
contains a non-removable electronics module that includes:
•
A Sensor Board with solid-state Attitude and Heading Reference System (AHRS) and
digital Air Data Computer (ADC)
•
A Main Application Processor (MAP) board with Central Processing Unit (CPU),
graphics processor and system memory
•
An Input-Output Processor (IOP) board for integrating communications with other
aircraft systems
Also on the rear of the unit (
Figure 1-6
) are:
•
An access cover for removing and replacing the built-in backup battery
•
Pneumatic connections to the aircraft’s pitot and static systems
•
44-pin D-sub connector for electrical connections to the PFD
•
A cooling fan, to cool the electronics and LCD backlights
The PFD mounts to the front surface of the instrument panel using the standard
installation kit; an optional flush-mount installation kit is also available.
