The following tables list the available AFCS vertical and lateral modes with their corresponding controls
and annunciations. The UP/DN wheel can be used to change the vertical mode reference while operating
in Pitch Hold, Vertical Speed, Altitude Hold, or IAS mode. Increments of change and maximum ranges of
values for each of these references using the UP/DN wheel are also listed in the table.
