Hi Andreas,

you can use Paparazzi sectors to create a polygon based geofencing functionality that allows you to do anything in case the aircraft crossed it

concerning this safety topic, it may be also of interest that there is
the political discussion in Germany/EU to allow a regulated operation of

private UAS use will probably be more restricted in Germany).
One of the discussed requirements for BVLOS  operation (besides some
kind of pilot licences, redundancy and mechanisms like parachutes) will
for sure be "geofencing" (which is virtually the same as obstacle
Thus I think this will be a must in the near future. However some kind
of geofencing is already implemented if I'm right: the
max_dist_from_home routine. May be that can be generalized to set other
way points with a circle line (distance) which must not be exceeded
(optionally in either dircection, not nearer or not farer away)? Of
course the reaction should not be "home mode" or "kill mode" as it is in
the moment, but just a turn away. Just some thoughts ..

to talk
about it ?
