Pilots will find the VNAV function useful for calculating vertical speed
requirements. In order to use the VNAV feature, the aircraft speed (or speed
entered in simulator mode), must be greater than 65 knots.
To calculate vertical speed requirements...
· Enter the initial (from) altitude.
· Enter the final (to) altitude.
· Enter the offset distance from the waypoint at which you will reach
your final altitude.
· Use the CLR key to select “BEFORE” if the offset is before the
waypoint, select “AFTER” if the offset is beyond the waypoint.
· Use the CLR key to select the VNAV waypoint from the active route.
The GPS 100 will display the required vertical speed.
To activate the VNAV function...
· Review the calculated vertical speed. If you wish to change the
vertical speed, enter the desired vertical speed.
· Move the cursor over “OFF” and use the CLR key to select “ON”.
When activated, this page will recommend the altitude (FROM altitude on line
1) and vertical speed (on line 3) required to complete the maneuver. NOTE:
The altitude and climb rate displayed on the VNAV Planning Page are only
