Just to give folks an update here and to express my extreme concern and caution of the RTH feature.
DJI assessed all my data and found me responsible for the damages. Now, let me tell you the rub, and why this is kind of scary.
I'm a certified remote pilot, I also have extensive knowledge of aviation and dealing with autonomous flight control.
The aircraft had acquired and maintained at least 12 satellites during the entire flight, it has ultrasonic sensors that work with the GPS to let it know how high it is off the ground, also, the stereo downward and forward facing cameras that allow it to find a nice place to land if it has to. With that said, my concern here with DJI was that while I agree it's great for the aircraft to take control in the event of a loss of link between the pilot and the aircraft, I don't however think the aircraft should follow the same RTH process when it's actually at home, 8' off the ground and in the process of being maneuvered for landing. This is what happened, I was in the process of landing the aircraft when it took control away from me and went into the same exact RTH process as though it had lost link with the pilot and was more than 100' away from it's home point.
Why would DJI do this? In my explanation I had complete control of the aircraft, was right beside it in a descent to land it and under my flight rules I'm supposed to maintain VLOS and only rely on the telemetry data if I've lost visual. Further, why would DJI have the same exact parameters for RTH if the aircraft is already home and at such a low altitude? This is extremely dangerous and it's a safety hazard. If someone had been near that aircraft when it took control away from me they could had been seriously injured if not fatally injured. DJI is probably the most technologically advanced company I've come across when it comes to this area, they are even more advanced in flight than some private aviation manufacturers. So, why would they overlook this? I personally feel it was just easier to apply the same RTH parameters to all facets when the aircraft was low of battery or when it lost signal with the pilot. But, this should not be, if it was a rush to get the Mavic out and even more of a rush to create DJI GO 4 it should had been suspended until all safety concerns were satisfied, especially with autonomous control, even more so when the aircraft takes control. Further, DJI has no idea what was going on, they were not there, all they have is flight data and that flight data shows the telemetry, why would someone not be more concerned about this? Would it take someone being fatally injured to have them really conduct safety simulations under all scenarios regarding RTH and autonomous control? I sure hope not, and by them not taking responsibility, that means that they didn't take my case seriously and they really don't care. I've already sent an email stating I'm referring this to the FAA because in my conversations with them one issue they do want to better understand is autonomous control and the safety around it. I only hope DJI get's serious after this complaint to the FAA because I am positive they will follow up with DJI over it. It pains me to do it, but I wasn't taken seriously, I wasn't even granted the chance to speak with the person making this assessment. That's a problem, maybe after all this it will spare future or current owners of basically all of DJI's aircraft the hell DJI has put me through and the Russian Roulette they're playing with peoples lives and well-being.
