Flying time : Total time when speed is greater than 35 knots.
Stopped time : Total time unit was on with a GPS fix and speed was less than  knots.
trip time : Total time the unit is on regardless of GPS fix.
Partial dist : Total distance since reset.

The Vertical Navigation (VNAV) function prepares a descent profile and recommends a descent
to the altitude of the destination of the active Flight Plan or to some OFFSET point from the
destination. The Vertical Situation Indicator in the HSI display is activated with this function (the
units of measure used for the values entered here are selected from Units Setup menu in the System
Setup Menu, see Par. 14.5). This feature requires that a Flight Plan be activated.

User data is entered in the fields at the bottom half of the screen. To set Vertical Navigation
parameters use ‘ENTER’ to edit the selected field (a box appears around the active field) and the
cursor key to move between fields. Press ‘CLEAR’ to return to Calculator menu.
Note
The Vertical Navigation solution estimates the target altitude (altimeter reading) from glideslope, distance to the
Waypoint, and the total altitude change. GPS altitude is not accurate enough for stand alone vertical navigation.
Some values are automatically displayed. Time To Go, Distance, Descent Rate and Altitude From
are based on current GPS data. An Altitude To is displayed if a Traffic Pattern Altitude for the
destination exists in the Database. Altitude From, Altitude To, Offset Distance and Glide Slope can
be edited. Vertical Navigation is a full screen page with the following structure:
