NOTE:
With Altitude Controls set to
Simplified
, the user will not be able to
pre-select a new altitude while ALT mode is already active.
•
Selecting Altitude Hold (ALT) Mode causes the Selected Altitude (Altitude Bug)
to change to the current aircraft altitude.
•
There is no longer a difference between the Selected Altitude (Altitude Bug) and
the Target Altitude for Altitude Hold (ALT) Mode.
•
After Altitude Hold (ALT) Mode captures the Selected Altitude, subsequent
changes to the Selected Altitude will cause ALT Mode to climb or descend
towards the new Selected Altitude.
•
Subsequent vertical speed adjustments are in increments of 100 fpm, with
the exception that the user cannot adjust the target vertical speed to a
value that would cause the aircraft to fly away from the Selected Altitude.
•
Unlike
Select VS Mode
described previously, this option does not switch
to VS mode. Instead, it displays a vertical speed bug.
•
The initial vertical speed used for climb or descent towards the new altitude
is determined by the Default Vertical Speed fields as described previously.
•
When Altitude Hold (ALT) Mode has captured the Selected Altitude, the vertical
speed bug is removed and vertical speed adjustments have no effect.
3.1.13 VERTICAL MODES
The 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 Indicated Airspeed modes. The
NOSE UP/DN
Wheel can be
used to change the vertical mode reference while operating under Pitch Hold, Vertical
Speed, Indicated Airspeed, or Altitude Hold modes. Increments of change of values for
each of these references using the
NOSE UP/DN
Wheel, are also listed in the table.
