The EADI displays information that has been gathered
from the AHRS unit and other navigation sources and
then after being sent through the SGU, (symbol
generating unit), it appears on the EADI EFIS screen.

Pitch and Roll Information:
Roll information is displayed on the EADI by fixed
reference marks at 0, 10, 20, 30, 45, and 60 degrees.
Pitch information is displayed by means of fixed
reference marks with 5 degree increments. The scale
is marked from -85 to +85 degrees.

The Aircraft Symbol:
The aircraft symbol serves as a stationary
representation of the aircraft’s position with reference
to the horizon. It shows both pitch and bank angles.

Flight Director Command
Bars:
The flight director command bars serve as a guide as
to how to position the aircraft’s attitude to achieve a
desired flight path.
The flight director is a dual cue device which will
command both pitch and roll changes to satisfy a given
flight path, according to the mode selected.

Flight Director Command
Bars:
In this example, the command bars are dictating a
pitch up and a bank to the right.
* One thing to remember is that the roll bar (the Vertical
Line) is a desired bank indicator.

If the command bar indicates a turn to the right, but
your desired course is to the left, it indicates that you
have over-banked. So decrease your bank angle and
the command bar will start to re-center the bar.
* This will be most noticed with the selection of low
bank mode on the flight director panel.
