requested. While synchronized,
two white plus(+) signs will indi-
cate the location of the absolute
horizon. A momentary (push on -
push off) action switch must be
used to request pitch offset sync
or return to absolute pitch with no
o f f s e t .
Note: Pitch offset sync is a fea -
ture intended for use on rotary
wing ar icr aft only, it is not
intended for use on fixed wing
aircraft. If a power reset occurs
(this includes ADI Down and/or
Composite modes), the pitch
offset sync will be turned off
and the attitude display
returned to normal.
In the event of a pitch or roll atti-
tude failure, the pitch scale, roll
scale, roll index pointer, blue sky
and brown ground are removed
from the display. Centered just
below the roll scale, a RED
“ATTITUDE FAIL” enclosed in a
RED box will be annunciated.

PITCH ATTITUDE
A moving white simulated hori-
zon line rotates angularly with the
roll of the aircraft and moves up
and down with the pitch of the
aircraft. Blue sky above the hori-
zon and brown ground below the
horizon align with the horizon line
as it follows the aircraft
’ s pitch
and roll. Pitch scale reference
marks extend above and below
the horizon line indicating 5,10,
15, 20, 25, 30, 35, 40, 45, 50, 55,
60, 65, 70, 75, 80 and 90
degrees. Refer to Figure 4.2.3.

Beginning with software ver-
sion 13, Pitch Offset Sync can be
configured to allow the displayed
horizon and pitch scale to be off-
set by up to 10° above or below
the absolute source. Intended for
use in rotary wing aricraft only,
the offset (10° maximum) allows
synchronization of the displayed
horizon to the current aircraft
pitch when synchronization is
