Failure Indications for ATT, MADC,
Attitude Reference System Failure -- Failure of either the pitch or
D
roll data is indicated by removing the pitch scale markings, turning
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
D
IAS and altitude scales, data is removed from the current value
pointer, the scale markings are removed and a red X is drawn
