Hello there. I've had my Mavic air for about six months and this has never happened. I launched my Air from my boat, set the home point as my current location, and set it to active track so it would shoot video of me running down the river. After canceling the first RTH warning, I stopped the boat and began manually flying, bringing it in towards the boat so I could land into my hand. I've successfully done this over a dozen times. Approximately 10 seconds before landing into my hand and 37% battery remaining, the signal drops, it ascends yo 30 meters, and begins its RTH. That was the last I saw of it. There is no telemetry after it lost the signal, so I don't know if it made it or not.
Question 1: when it began the RTH, are the obstacle avoidance sensors still active or do they disengage? Since we had gone around a bend in the river, it ascended and took a direct line back to home rather than back up the river. There is a ridgeline that is higher than 30m that it would have had to get over if it made it home. The answer to this question will determine if I have to look on land or in the drink.
