7.3 AFCS MODES
The AFCS is capable of operating in a variety of independent Lateral Modes, Vertical Modes and Combination
of both the Lateral and Vertical Modes.
VERTICAL MODES
The following table lists the vertical modes with their corresponding controls and annunciations. The mode
reference is displayed next to the active mode annunciation for Altitude Hold, Vertical Speed, and Flight Level
Change modes. The
NOSE UP/DN Keys can be used to change the vertical mode reference while operating
under Pitch Hold, Vertical Speed, or Flight Level Change Mode.

Table 7-2 Flight Director Vertical Modes
PITCH HOLD MODE (PIT)
When the flight director is activated (the FD Key is pressed), Pitch Hold Mode is selected by default. Pitch
Hold Mode is indicated as the active vertical mode by the green ‘PIT’ annunciation. This mode may be used
for climb or descent to the Selected Altitude (shown above the Altimeter), since Selected Altitude Capture
Mode is automatically armed when Pitch Hold Mode is activated.
