Wpt' (AGL) or 'MSL', (Figure 2-52) and press

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 refer-
ence 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
2-54) and use the small and large right knobs
to enter a new rate. Press the ENT Key when
finished.
