1.1.1. E5 Dual EFI Unit
The E5 Dual EFI Unit is a digital system that consists of a high resolution, six-inch
diagonal color LCD display, user controls, photocell, and micro SD 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 (

) 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 display
• A cooling fan, to cool the electronics and LCD backlights
The E5 mounts to the front surface of the instrument panel using the standard
installation kit; an optional flush-mount installation kit is also available.
