Good steer Ralph, this wind principle is very evident in mountainous terrain also. Thanks, this is very informative.I’ve posted this video before, but for those not familiar with flying light drones around tall buildings, here are some facts from Nav CANADA. It may not be the situation here since he said he lost the link, but you dont need much wind to have an uncontrollable situation around tall buildings.
|Okay, now what is this?|
The maximum height a DJI drone can fly to is 500 meters. This tower is higher than that. Of course, it lost signal due to the large building in between the drone and the controller and initiated a Return-To-Home sequence, which tells the drone to ascend to the set height in the DJI Fly app, in this case probably 500 meters above the takeoff point, and fly back to the takeoff position.
In the reflection, the drone was visible, which looked like a DJI Mini 2, which doesn't have obstacle avoidance sensors and couldn't possibly avoid the building. It flew right into it. The inexperience of the pilot and lack of planning, it seems.
What was the right thing to do? Not fly there. But I do understand that some people want to fly in spots like that, well, then the right thing would be to set the failsafe behavior (aka what happens when the drone and remote lose signal) to hover, then the drone would just hover in place, and the pilot would move, get closer to the drone, reconnect and land safely, instead, it was set to RTH, which is the safest option in the vast majority of cases, but not here.
And not to mention, this was beyond visual line of sight, which isn't allowed in most places, assuming there it is also the case.
I hate seeing stuff like this on the internet because it means more restrictions for drone pilots like me… I'm not trying to blame the pilot here, because of course it wasn't intentional, but still, you have to be a bit more cautious when flying, and plan at least a bit before the flight, so stuff like this doesn't happen, hopefully.
