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 ush-mount installation kit is also available.
