the entire attitude sphere to cyan and displaying a red ATT FAIL in
the top center of the attitude sphere.

Micro Air Data Computer (MADC) Failures
-- In the case of the
IAS and altitude scales, data is removed from the current value
pointer, the scale markings are removed and a red
X
is drawn
through the scale. The digital Mach CAS display failure is shown by
replacing the numerical value with amber dashes.
In the case of the vertical speed, the current value pointer is
removed, and amber dashes replace the digital display.
