Additionally, there are red warning chevrons which appear at 45
and 65 degrees pitch up and 35, 50, and 65 degrees pitch

Roll Attitude
-
The roll attitude scale displays actual roll
attitude through a movable white index pointer and fixed white
scale reference markings at O, 10, 20, 30, 45, and 60 degrees.
The 30 degrees reference mark is highlighted and shows up as a
brighter shade of white.
(d) Aircraft Symbol - The stationary yellow aircraft symbol is used
to develop the relationship between aircraft pitch and roll
attitudes and the movable sphere. Additionally, the symbol is
used to align to the flight director command cue in order to
satisfy the commands of the selected flight director mode.
(e) Attitude Source Annunciation - The selected attitude source is
not annunciated if it is the normal on-side source for that
indicator. As other attitude sources are selected they are
annunciated in white left of the attitude sphere. When the
pilot and copilot source are the same, they are annunciated on
both displays in amber. Source selection for attitude is
accomplished through the display controller as shown in Figure
203.
