7.3 VERTICAL MODES
Table 7-2 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/NOSE DN Keys 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/NOSE DN Keys are also listed in the table.
