ENT
Key.
10) With the ‘TARGET ALTITUDE’ field highlighted,
turn the small and large
FMS
Knobs to select
the target altitude. If the selected altitude is
above the current aircraft altitude, a profiled
climb is created. If the selected altitude is
below the current aircraft altitude, a profiled
descent will be created.
11) Press the
ENT

in the ‘TARGET VERTICAL SPEED’ field. The

descent rate.

FMS
Knobs to enter the desired vertical speed. Press
the
ENT
Key when finished.
With the profile set, the vertical speed required (VSR)
is displayed. Expect the following to occur when using the
vertical navigation feature:
At one minute prior to reaching the Bottom Of Climb
or Top Of Descent point (gray arc), the message ‘APPR
VPROF - Approaching VNAV Profile’ is displayed as a PFD
alert. The descent (or climb) angle also locks to prevent
changes in speed from altering the profile. If selected,
the vertical speed required (VSR) readout on the default
NAV and map pages shows the desired vertical speed to
maintain the proper descent (or climb) angle. At 500 feet
above (or below, for a climb) the target altitude (white
arc), an ‘APPR TRG ALT’ - Approaching Target Altitude”
message is provided. The VSR readout on the Navigation
Map Page is blanked out at this point.
