3.1.2 ROLL ATTITUDE

A white stationary roll scale with
an orange zero degree index pro-
vides the reference for the bank
angle pointer. The white sky
pointer moves in relation to the
roll scale to indicate degrees of
aircraft right or left bank. The
fixed scale is marked at 10, 20,

30, 45, 60, and 90 degrees, with the 30, 60 and 90 degree marks
being thicker and longer to allow easier recognition. The 90° marks
also serve as the center position on the speed command and glides-
lope scales.

3.1.3 SYMBOLIC AIRCRAFT

Located in the center of the display is the
fixed yellow aircraft symbol with a black dot
at the center. The pitch and roll attitudes of

the aircraft are displayed by the relationship of the fixed symbolic air-
craft and the movable horizon. The symbolic aircraft is flown to satisfy
the command cues of the flight director.

3.1.4 SPLIT CUE FLIGHT DIRECTOR

The split cue flight director is represented
by vertical and horizontal magenta bars in
the center of the EADI display about the
fixed aircraft symbol. The command bars
appear to move in front of the yellow air-
craft symbol but behind the black dot. The
horizontal bar provides pitch commands
and the vertical bar provides roll com-
mands. The bars are independently driven
and can indicate pitch only, roll only, or
combined pitch and roll commands. The flight director commands are
satisfied by flying the center black dot of the symbolic aircraft to the
intersection of the flight director command bars. The selection of the
same flight director computer by both Captain and First Officer is
annunciated by an “FD” (black text in a yellow circle). The annuncia-
tor and the command bars are removed from the display when the
flight director mode is not active.

The decrab symbol is presented as a white “V” above the symbolic
aircraft. The decrab symbol slides left or right along the wings of the
symbolic aircraft to indicate the rudder command.
