2.7 NUMERIC DISPLAY

2.7.1 GENERAL
If preselect capability is installed, the numeric window normally displays Selected Altitude in units
of "FT". This window also displays the reference for Vertical Speed mode (if engaged) for 3
seconds after engagement or the last press of the UP or DN buttons or when CWS is pressed.
However, the display will default back to displaying selected altitude if the inc/dec knobs are
turned. The display units will change to "FPM" when displaying the VS reference. If preselect
capability is not installed, the numeric display will always display the VS reference when VS is
engaged.

2.7.2 PITCH REFERENCE CONTROL

The vertical reference may be changed by use of the UP or DN buttons, as shown in the following
table. The continuous rate change is used when the UP or DN button is pressed continuously for
more than 0.75 seconds. The VS reference is limited to the certified limits.

*The ALTitude hold reference is not displayed and synchronizes to aircraft upon trim switch
release.

2.7.3 BARO SET

The numeric window will also display the baro--setting for 3 seconds after pressing the BARO
button. If remote baro--set is not selected, this also enables the rotary knobs to input the
baro--setting. Remote baro--set selection is used to accept baro input from a KEA 130A altimeter.
Holding the BARO button for at least 2 seconds will toggle the baro set display units between "HPA"
(hecto--Pascals) and "IN HG" (inches of Mercury).
If remote baro--correction is not selected, the current baro setting will flash on the display after PFT.
To cancel the flashing, the pilot must press the BARO button (to acknowledge the current baro set)
or turn the inc/dec knobs until the proper baro set is displayed.
If remote baro--set is selected, but the baro set input is invalid, the unit will "prompt" the pilot for
baro setting, as described above, after the failure is detected. In addition, it prompts each time the
selected altitude is changed.
