Wpt' (AGL) or 'MSL', (Figure 3-52) and press
the ENT Key. 'Above Wpt' uses the altitude
of a destination airport as stored in the
Jeppesen NavData Card. 'MSL' lets the pilot
set a specific target altitude for any waypoint
category: airport, VOR, NDB, intersection, or
user waypoint.

Turn the small right knob to select 'Before'
or 'After', and press the ENT Key. This setting
designates whether the offset distance defines
a point before the aircraft reaches the target
reference waypoint, or after the aircraft reaches
the waypoint.
When using a flight plan, the target reference
waypoint itself can be specified from the
waypoints contained in the flight plan. By
default, the last waypoint in the flight plan is
selected. To select a different waypoint, turn
the small right knob to select the desired
waypoint and press the ENT Key.
The default profile utilizes a 400 fpm descent
rate. To change the rate, turn the large right
knob to highlight the 'VS Profile' field (Figure
3-54) and use the small and large right knobs
to enter a new rate. Press the ENT Key when
finished.
