3.9 VERTICAL NAVIGATION PAGE

The GNS 430' s Vertical Navigation Page (the last NAV
page, see Figure 3-48) creates a three-dimensional profile
to provide guidance from the present position and altitude
to a final (target) altitude at a specified location. This is
helpful when descending to a certain altitude near an
airport or climbing to an altitude before reaching a route
or direct-to waypoint (Figure 3-49). Once the profile is
defined, message alerts and additional data on the Default
NAV Page and the Map Page provide guidance to the
pilot.
