On entry to Screen 59, if
there is no active way-
point the DESTINATION
box will read NO WAY-
POINT. You must have
an active waypoint in
order to activate VNAV
Mode. The name of the
destination waypoint will
be shown if available,
otherwise NO WAY-
POINT will be displayed.
Once in the VNAV Screen
you must enter the cruise
altitude (the altitude FROM which you will descend), the final altitude (the
altitude TO which you want to descend), the rate of descent (in FPM feet
per minute) and the distance before the upcoming waypoint that you
want to achieve the new level BY.
On entry to this Screen, the FROM value will default to GPS altitude if
your unit has an internal GPS receiver or to 5000 feet if your unit is in
External GPS mode (or the last set value). The TO value will default to
1500 feet (or the last set value). The BY value will default to 5.0nm (or
last set value) and the AT value will default to 500fpm (or last set value).
The DESCEND IN box will show an active countdown of the time left
before you should start your descent and will be recalculated if you
change any of the four variables (FROM, TO, BY or AT).
If Screen 59 is entered then exited by pressing Key 1, VNAV mode is not
activated, the values are simply retained for use later in the flight.
