Description

Distance calc when checking if tracklogpoint is correct in relation to a turnpoint cylinder is in some cases done by converting the coordinates to UTM and using pythagoras. This works fine for short distances in same UTM zone but may give small differences from distance calculations as done by flight-instruments.

Reason for doing this was speed of calculation.

All other distance calculations is done using Haversine formula with earth radius 6371000 meters (FAI def. SC gen. section 7.3.1.1).

This will now be used also in the above case.
