AOA Analog Scale - The AOA tape is a fixed scale with moving
current value pointer.
The white scale markings on the display
range from 0.2 to
1.1 in 0.1 AOA increments.
The scale is
labeled in white at 0.2 AOA intervals. The scale is
color-
banded to show AOA exceedance
ranges. The scale is white
between O and 0.64 AOA, amber between 0.64 and 0.80 AOA,
and
red between 0.80 and 1.1 AOA.
AOA Digital Readout - A digital readout of the actual
normalized AOA
is magnified and presented in the current value
pointer.
The digital data is readable to a 0.01 AOA
resolution. The digit colors change to match the indicated
range on the scale as defined above.
AOA Target Bug -
The green triangular shaped AOA target bug
moves along the inboard side
of the VS scale. The target value
is settable by the pilot through the use of the displa~
controller (Figure 205).
(7) Comparison Monitor Annunciation
Selected pilot and copilot input data is compared by the symbol
generator. If the difference between the data exceeds predetermined
levels, the out-of-tolerance symbol is displayed.
These
annunciations are displayed
in amber and are located to the left,
adjacent to the attitude sphere.
A list of the compared signals and
displayed cautionary symbols are given below.
