VNAV (Vertical Navigation) Guide helps you plan and monitor descents with simple inputs like destination, arrival altitude, slope or vertical speed and groundspeed (VS/GS) and cruise altitude. Select your destination from a list of world airports or create your own. Based on arrival altitude, location and current cruise altitude it calculates the top of descent (TOD) point. Prior to descent your remaining distance to TOD is displayed continuously. During descent your height relative to the selected slope and distance to destination are displayed continuously.
