Wind Calculation - AvMap EKP-IV User Manual

Fig. 10.4a - Vertical Navigation function
Vertical Navigation can be activated (On) only if a Flight Plan is active (desti-
nation present).
Destination point for Vertical Navigation is the last point of the Route or
destination of GoTo mode.
Prior to the Descent Point being reached the Distance To Go displays TO,
Time To Go to Descent point and Descent Rate from the current position.
After passing Descent point the system displays TO, Time To Go to the Des-
tination and Target altitude based on actual descent profile. Time To Descent
or Target ALT values can be displayed in the Data Window of Moving Map
and HSI modes.
The Vertical Navigation value displayed in the HSI is calculated as a difference
between current altitude (from GPS) and Target altitude.
