I vaguely understand the concept of geofencing; and how it prevents motor activation in certain restricted zones. My question is what happens if your flight originates in a non-restricted zone; but, during flight, you inadvertently wander into a restricted zone? Does geofencing activate a RTH, give a warning with time to leave the restricted area, initiate an immediate landing, or does it just shut the motors down resulting in a crash and possibly a lost drone?
