EADI Operation
2.2.2 Issued 8/10 SW 04/05/06/07/08/09/10/11/12/13/14/15/16
BRIGHTNESS
The BRT knob controls the dis-
play brightness.
N o t e : The display brightness
control provides full range dim -
ming to allow night operation in
no- or low-light situations. The
lower limit of the display bright -
ness may appear as an inoper -
ative tube during normal day -
light operation. It is therefore
advisable to check the BRT
knob setting during preflight
test.
To ensure maximum display
tube life, it is highly recom -
mended that the display be
operated at the lowest accept -
able brightness level.
DH SET
To set the Decision Height, pull
out and turn the DH knob. Turn-
ing clockwise will increase the
Decision Height selected, turning
counter clockwise will decrease
the Decision Height. The DH set
knob is variable rate, the faster
the knob is turned the greater the
change in a given amount of
rotation. The Decision Height
range is from “OFF” to 2,500 feet
and will be displayed in one foot
increments up to 500 feet and
then in 10 foot increments to
2,500 feet.
Once the desired DH is selected,
push in the DH set knob to lock
the selected DH altitude. If DH is
set to OFF, the “DH” annuncia-
tion will not be displayed.
RALT TST
Pressing the RALT TST (Radio
Altimeter Test) push button pro-
vides a discrete output to the
Radio Altimeter initiating its self
test function.
The height displayed on the
EADI will depend on the type of
Radio Altimeter installed. For
details on this information refer to
