The following tables list the available AFCS vertical and lateral 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 Wheel can be used to change
the vertical mode reference while operating under Pitch Hold, Vertical Speed, or Flight Level Change
Mode. Increments of change and acceptable ranges of values for each of these references using the
NOSE UP/DN Wheel are also listed in the table.

* ALTS arms automatically when PIT, VS, FLC, TO, or GA is active, and under VPTH when the Selected
Altitude is to be captured instead of the VNV Target Altitude.
** ALTV arms automatically under VPTH when the VNV Target Altitude is to be captured instead of the
Selected Altitude.
*** ESP equipped aircraft only. LVL mode is entered from an automatic engagement of the autopilot due
to the aircraft remaining outside of the normal flight envelope for an extended amount of time.
