Section 10
Vertical Navigation (VNAV)
The 500W-series Vertical Navigation Page allows
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
and additional data on the Default NAV and Map
Pages keep you informed of your progress.
To display the Vertical Navigation Page, press the
VNAV key.
