VNAV and VCALC Options
If your GTN has system soware 6.5 or later, you can view information about the current VNAV Prole and
constraints. See “Using Vertical Navigation (VNAV) and Along-Track Osets” earlier in this manual.
If your GTN is using system soware prior to 6.5, or if you chose to retain the legacy VCALC (vertical
calculator), VCALC appears on the Utilities page.
When ying an active ight plan or proceeding direct-to a waypoint, VCALC computes the required ver-
tical speed and displays the time when you should start a descent to reach a specied altitude at or near a
waypoint location. VCALC is not available when groundspeed is less than 35 knots or aer the FAF on an
approach. When VCALC is active, the GTN displays messages on the navigation pages to alert you to begin a
descent.
