Vertical Navigation (VNAV)
The 500W-series VerticalNavigationPageallows
you to create a three-dimensional profile which guides
you from your present position and altitude to a final
(target) altitude at a specified location. This is helpful
when you’d like to descend to a certain altitude near
an airport. Once the profile is defined, message alerts
andadditionaldataontheDefaultNAVandMap
Pages keep you informed of your progress.
To display the Vertical Navigation Page, press the
VNAV key.
NOTE: To use the vertical navigation features,
your ground speed must be greater than 35 knots
and you must be navigating to a direct-to desti-
nation or using a flight plan, and not be in SUSP
mode.
