7.2.1 Final glide calculation
Final glide is a function calculated from distance, target elevation, altitude, wind component,
MC setting and Bug setting. If V7 get enough data, everything is done automatically (GPS
and PDA provides all necessary information – position, target elevation). If such data is not
available, pilot must manually enter missing data, that V7 will calculate final glide.
