Fig. 10.4a - Vertical Navigation function
Vertical Navigation can be activated (On) only if a Flight Plan is active (destination 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 Destination 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.
