MODE ANNUNCIATION
Flight director mode annunciations are integral to the primary flight displays. The vertical and lateral
modes are annunciated along the top of the display. Armed vertical and lateral modes are annunciated in
white and appear slightly to the left of the position of the captured vertical and lateral mode annunciations,
which are presented in green. Lateral mode annunciations are located to the left of top center and vertical
modes are annunciated to the right of top center. A white box appears around a capture or hold mode for
five seconds after mode transition. Lateral and vertical mode annunciations and transitions are listed below:
VOR A NAV mode (VOR) is armed or has been captured and is being tracked.
HDG Heading select mode engaged
LOC Localizer has been armed or captured.
VAPP VOR approach selected or course capture has occurred.

Mach is automatic as the airplane climbs through 29,000 feet altitude, and Mach to airspeed occurs
automatically as the airplane descends through 28,750.
