Vertical Navigation Function

The last option featured on the GPS 92’s E6-B menu

is the vertical navigation (VNAV) function, which lets you

create a rate of descent profile from your present position

and altitude to a final altitude at a specified location. To

use the VNAV feature, your aircraft’s ground speed must

be greater than 35 knots, and you must be navigating an

active GOTO or route.

To perform a VNAV calculation:

1. Highlight the ‘From’ field and press

2. Enter the initial altitude and press

3. Press

. Enter the final ‘To’ altitude and press

4. Press

. Enter the offset (the distance from the way-

point you’ll be referencing for your final ‘To’ altitude) and

press

5. Select the ‘Before’ or ‘After’ option for the distance off-

set and press

to confirm.

6. Press

. Enter the waypoint you want to use as a

reference for your final altitude. If you are navigating an

active route, the waypoint field will offer the active-to

waypoint for the reference waypoint (the waypoint page

will appear for you to confirm).

7. Press

to confirm the waypoint. The vertical speed

for the descent will appear in the ‘At’ field. To select a

faster or slower rate of descent, press

, enter a

new rate and press

to confirm.
