6. V/S-FPA Display Window
Displays vertical speed or FPA. Display is blank if V/S or FPA are not
engaged. When FPA is selected, the value is in degrees and tenths. When V/S
is selected, the value is in fpm.
7. Pitch Wheel
Rapid rotation results in large changes in the display window. Slow rotation
results in 100 fpm (or 0.1 degree) changes per detent. A vertical speed bug is
positioned on the PFD vertical speed tape corresponding to the selected
vertical speed.
Roll to select:
• Disengages PROF, speed on pitch, altitude hold, and glideslope modes if
LAND is not annunciated.
• Display window and target initializes to plus or minus 100 fpm (or 0.10
degree FPA) if engaged in altitude hold. Otherwise, initialization is to
current vertical speed/FPA. Subsequent wheel changes result in changes
in vertical speed/FPA selection.
• Pushing PROF resumes FMS profile operation at the selected vertical
speed as an FMS edit.
When the pitch wheel is moved, the AP will cancel the altitude capture mode
(if engaged) and will not re-engage in altitude capture until the pitch wheel
has come to rest for 2 seconds. The selected altitude will not be captured if
the pitch wheel is repeatedly adjusted. In this case, the AP will toggle between
vertical speed mode and altitude capture.
