Hello all. M2P using DJI Go. I gather the legal altitude limit is set by default at 120M (400') in the DJI app. I further gather that the app sees this as the height above the launch point, so if one flies downhill you go into negative altitude and flying uphill of course the altitude will increase. Question is: What happens if one goes vertical at launch to the max 120m and then tries to fly uphill? My brain is telling me that the drone won't be able to climb because it thinks it is at the max. Obviously this can't be the case. Can someone explain to me how the program responds in this scenario, and how does one safely fly up a mountain slope without losing your clearance to ground level. Thanks
