Welcome and Introduction
CHAPTER 1 WELCOME
Welcome to Aspen Avionics’ Evolution Flight Display (EFD) system, the
most flexible, expandable, and upgradable Electronic Flight Instrument
System (EFIS) available for General Aviation aircraft. Designed to replace
traditional mechanical primary flight instruments—in whole or in part,
all at once, or in phases. This modularity and upgradability allows the
system to grow with you and your airplane, over time and affordably.
The EFD system is built around the EFD1000 Display Unit, which replaces a vertical pair
of your six primary flight instruments. The EFD1000 has a bright, high-resolution, sixinch
diagonal LCD display, and a number of knobs and buttons the pilot uses to control
the system. The three-inch diameter, four-inch deep can on the back of the display
slides into existing panel cutouts (where the top mechanical instrument used to be)
(Figure 1-1).
