VNAV Limitations
The GTN allows you to create a vertical navigation path with multiple altitude
constraints in the flight plan. These altitudes are removed when the flight plan
is stored in the flight plan catalog.
Most flight plan waypoints may be assigned an altitude constraint for use in
vertical navigation. Exceptions include:
• Flight plan legs containing headings
• Flight plan legs that terminate at an altitude (e.g., a climb to 1,800 ft before
making a turn and proceeding direct to fix)
