VNAV (Vertical Navigation)

The VNAV tab in the Main Menu provides settings for the vertical
navigation feature. These settings create a three-dimensional profile
that guides you from your present position and altitude to a final
(target) altitude at a specified location.
Once the VNAV profile is defined, message alerts help keep you
informed of your progress. The teal bar on the HSI on the Panel
page displays your VNAV profile.
To use the vertical navigation feature, your ground speed must be
greater than 35 knots and you must be navigating a Go To or a route.
The "Approaching VNAV Profile" message appears one minute
prior to the initial descent point. The descent angle locks to prevent
changes in speed from altering the profile. The VNAV feature does
not take into account any changes in groundspeed that occur during
the transition from level flight to descent or climb.
At 500 ft above the target altitude, the "Approaching Target
Altitude" message appears, the time to vertical navigation goes
blank, and the VNAV indicator disappears from the Panel page.
NOTE: The GPSMAP 296 is a VFR navigation tool and should
not be used to perform instrument approaches. VNAV is only a
VFR navigation instrument and is not intended for instrument
approaches.

Using the VNAV Feature

Use the VNAV (Vertical Navigation) feature to ensure that you are
flying at the proper altitude. The VNAV Indicator appears on the
HSI (Panel page) as a horizontal teal bar, as shown in the image on
the next page. A pop-up message appears when you are approaching
the VNAV Profile. When the bar is in the vertical center of the HSI,
you are at the proper altitude for the VNAV Profile. Make sure
VNAV Indicator is On in the options menu.
