ATTITUDE (continued)
Roll Indicator (refer to Figure 1-3)
The roll indicator consists of a roll scale and a roll pointer. The white
scale lines are set at +/- 10, 20, 30, 45, and 60 degree tick marks with a
downward white triangle representing the 0° mark. The roll pointer is an
upward pointing triangle located on the inner arc radius of the roll scale.
Conguration Options: If the roll pointer is congured for xed the roll
scale rotates around the aircraft reference symbol boresight and has a roll
angle range of ±180°. If the roll pointer is congured for rotating the roll
pointer rotates around the aircraft reference symbol boresight and has a
roll angle range of ±180°.
Aircraft Reference Symbol (refer to Figure 1-3)
Located in the center of the attitude display, the aircraft reference
symbol is a xed square boresight with L-shaped “wings” to each side
of the boresight. The symbol provides a xed reference as compared to
the attitude background, pitch ladder, and roll indicator to determine the
aircraft’s pitch and roll attitude. The aircraft is at zero-degree pitch when
the intersection of the blue (sky) and brown (ground) articial horizon
intersects the boresight .
