To create a vertical navigation profile:
1. Press the small right knob to activate the
cursor.
2. Turn the large right knob to highlight the
target altitude field.
3. Turn the
small
and
large right
knobs to select
the target altitude and press
ENT
.
4. Turn the small right knob to select “Above
Wpt” (AGL) or “MSL”, and press
ENT
. “Above
Wpt” will use the altitude of a destination air-
port as stored in the Jeppesen NavData card.
“MSL” lets you set a specific target altitude
for any waypoint category: airport, VOR, NDB,
intersection or user waypoint.
5. Turn the small and large right knobs to select
a distance from the target reference waypoint
and press ENT . If the target altitude should
occur at the target reference waypoint, enter
a distance of zero.

or “After”, and press
ENT
. This setting desig-
nates whether the offset distance defines a
point before you reach the target reference
waypoint or after you reach the waypoint.
“After” is not available for the last waypoint.
7. When using a flight plan, the target refer-
ence waypoint itself can be specified from
the waypoints contained in the flight plan. By
default, the last waypoint in the flight plan will
be selected. To select a different waypoint, turn
the
small right knob to select the desired
waypoint and press
ENT
.
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.
