QNE altitude
QNE Altitude - is altitude without binding to Home point alt. In need for several situations:
- distinguish your altitude from the altitude of the aircraft using ADBS data on height >3000-5000ft. The use of such a height makes it possible to control flight levels, since the closer the planes are to each other, the more equal the atmospheric pressure is overboard;
- know the altitude in case the controller is rebooted in the air;
- see the height of the take-off point before arm;
