FLIGHT DIRECTOR (FD)
The Flight Director modes of operation can be divided into two major subgroups, the
Lateral modes and the Vertical modes. Only one lateral mode and one vertical mode
may be active (green) at any time; however, one lateral arm (white) mode and up to
two vertical arm (white) modes may be selected.
The armed and active modes are annunciated on both PFDs. Armed modes are
displayed in white below active modes, which are displayed in green. The lateral
modes are annunciated on the left side of the displays and the vertical modes on the
right side, above the attitude sphere. Low bank mode is annunciated via green
eyebrow on top of the attitude sphere.
