3. EADI/EHSI DISPLAYS
3.1 EADI DISPLAYS
3.1.1 PITCH ATTITUDE
A moving white simulated horizon
line rotates angularly with the roll
of the aircraft and moves up and
down with pitch of the aircraft.
Blue sky above the horizon and
black ground below the horizon
align with the horizon line as it fol-
lows the aircraft's pitch and roll.
Pitch scale reference marks
extend above and below the hori-
zon line indicating 2.5° incre-
ments within ±30° of the horizon
line and 20° increments from 40°
to 80° from the horizon line.
Red excessive pitch chevrons are provided between 40° and 90°
pitch up (on the sky background) and between 30° and 90° pitch
down (on the ground background).
When the aircraft pitch attitude is such that the horizon line is off the
display, a small portion (eyebrow) of sky or ground will remain to indi-
cate the direction of minimum pitch correction to return to level flight.
