Basic Operation > VNAV (Vertical Navigation) Setup Page The VNAV Page provides settings for the vertical navigation feature. These settings create a threedimensional profile that guides you from your present position and altitude to a final (target) altitude at a specified location. When defined, message alerts and data track your progress on the HSI Page. A VNAV indicator appears as a moving bar depicting the Vertical Deviation from the VNAV Profile. As you approach the initial descent point, the time to vertical navigation field (ETV) indicates the time to reach the initial descent point. 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. The "Approaching Target Altitude" message appears at 500 ft above the target altitude, the time to vertical navigation goes blank, and the VNAV indicator disappears from the HSI Page.
