Thanks for all the info on my other post about the Homepoint. Firstly re that again, I went out twice flying yesterday and on both occasion the controller spoke to me saying Home Point updated and I hadnt touched anything. It showed my position on the map spot on. Can that happen. And my second question, which sounds silly but its just for my info. Living near hills & mountains there are unlimited places for me to go off and practice with the camera etc. If I took off on the top of a hill and then flew out into the valley, how does the mavic air decide how high it is, when the ground suddenly appears hundreds of feet below and I have a max altitude setting off say 150ft. Hope that makes sense. Any, sorry for so many questions.
