ATTITUDE ROLL POINTER AND SCALE
The roll scale is displayed on top of the ADI. The roll scale consists
of a triangular roll pointer, short linear tick marks (at ±10° and ±20°),
and long linear tick marks (at ±30° and ±60°). Inverted hollow
triangles are displayed at 0° and ±45°. The KFD 840 has two options
for the roll pointer and scale.
Figure 3-5 Attitude Roll Pointer and Scale
The first option is a roll pointer. In this option the roll arc is stationary
with respect to the horizon and the pointer moves back and forth
across the arc. The attitude roll pointer indicates the current aircraft
roll attitude. The attitude roll pointer is a solid white triangle below
the roll scale. The attitude roll pointer moves to the left as the roll
angle increases and to the right as the roll angle decreases.
