VNAV (Vertical Navigation) The VNAV sub 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 location and altitude to a final (target) altitude at a specified location. When the VNAV profile is defined, message alerts help keep you informed of your progress. The teal bar on the HSI on the Panel Page shows 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. CAUTION: The GPSMAP 296 is a VFR navigation tool and should not be used to perform instrument approaches. VNAV is only a VFR navigation aid and is not intended for instrument approaches.
