8. The default profile utilizes a 400 foot-per-
minute descent rate. To change the rate, turn
the
large right
knob to highlight the “VS
Profile” field and use the
small
and
large
right
knobs to enter a new rate. Press
ENT
when finished.
The default profile is a 400 foot-per-minute
descent. Use the small and large right knobs
to enter a different vertical speed figure.
With the profile set, the vertical speed required
(VSR) is displayed on the Vertical Navigation Page.
Expect the following to occur when using the vertical
navigation feature:
• At one minute prior to reaching the initial
descent point, a message “Approaching VNAV
Profile” occurs. The descent 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 angle. Maximum VSR that can
be displayed is -6000 ft/min. If VSR exceeds
-6000 ft/min, dashes will be displayed.
• Course reversals are not included in the VNAV
calculations until the aircraft begins the course
reversal. While reversing course, VNAV includes
direct-to the course reversal wayopint in the
VNAV calculation.
• At 500 feet above the target altitude, an
“Approaching Target Altitude” message is pro-
vided. The VSR readout on the Default NAV and
Map Pages is blanked out, at this point.
Vertical navigation messages can be turned on or
off. (By default the messages are off.) Turning the mes-
sages off allows you to keep the profile settings you’ve
entered previously, without having them generate mes-
sages when the feature isn’t needed.
To disable/enable the vertical navigation (VNAV)
messages:
1. Press
MENU
to display the Vertical Navigation
Page Options menu.
2. With “VNAV Messages On?” highlighted, press
ENT
. Or, if the messages are already on and
you wish to turn them off, make sure “VNAV
Messages Off?” is highlighted and press
ENT
.
Select “VNAV Messages On?” to display the
vertical navigation alert message.
To restore the factory default VNAV settings:
1. Press
MENU
to display the Vertical Navigation
Page Options menu.
2. Turn the
large right
knob to highlight
“Restore Defaults?” and press
ENT
.
