Quite new on SD and I trying to get used on using this great software.
When in flightmode on an iPad and using the built-in GPS there are some erratic points which are registered. (cfr attached GPX EBGB-EBOS at the end of the flight & EBOS-EBGB at the beginning of the flight).
I can imagine that this is when the ipad lost GPS signal or has poor signal...

I am wondering if it would be not possible to drop the points which can be identified as abnormal based on preceding and following points.

This is pretty unusual. We do not want to start guessing at what points might be deemed "erratic" because of the potential for false positives, and the fact that this doesn't happen very often. If you find this happening often, you should consider exchanging your iPad for one where this doesn't happen.

I understand.
I have purchased an external GPS receiver (GNS-2000). since then I have not any erratic points anymore. I assume that the GPS reception to my Ipad on my knees in the C-152 was not good....
