8.19 VERTICAL NAVIGATION PLANNING (E6-B)
Pilots will find the GPS 95's vertical navigation (VNAV) function useful for
calculating vertical speed requirements. In order to use the VNAV feature,
aircraft ground speed must be greater than 35 knots.
To calculate vertical speed requirements...
· Place the cursor on the initial (Frm) altitude field.
· Enter the initial altitude and press ENT.
· Enter the final (To) altitude and press ENT.
· Enter the offset distance, from the desired waypoint, at which you will
reach your final altitude. Press ENT.
· Select “Before” if the offset is before the waypoint, or “After” if the offset
is beyond the waypoint, by pressing CLR.
· If an active route is being used: press CLR to select the route waypoint
to which the offset applies.
· You now have defined how far before, or after, the indicated waypoint
you wish to be at the final altitude. The GPS 95 will display the required
vertical speed.
