Vertical Navigation (Vnav) - Garmin G3X Touch Pilot's Manual

2.3 VERTICAL NAVIGATION (VNAV)

CAUTION: VNAV is only a VFR navigation aid and is not intended for instru-
ment approaches.
The Vertical Navigation Page provides settings for the vertical navigation feature.
These settings create a three-dimensional profile from the present location and altitude
to a final (target) altitude at a specified location.
When the VNAV profile is defined, the pilot is informed of the progress by message
alerts. A magenta chevron (VNAV Indicator) to the left of the altimeter on the Vertical
Deviation Scale shows the VNAV profile, and a magenta chevron (Required Vertical
Speed Indicator (RVSI)) on the Vertical Speed Indicator indicates the required vertical
speed to reach the target altitude.
The Vertical Navigation feature is only available when navigating a Direct-to or flight
plan, and the ground speed is greater than 35 knots.
One minute prior to the initial descent point the "Approaching VNAV Profile"
message appears and the 'Estimated Time to VNAV' (on Active Flight Plan Page) goes
blank. The descent angle locks to prevent changes in speed from altering the profile.
The VNAV feature does not take into account any changes in ground speed that occur
during the transition from level flight to descent or climb.
