There is lots of talk on this thread of number of sats required...... I'm not sure anyone remembers that these things will fly without GPS holding your hand. The initial story tells how the Mavic started to drift and a climb was initiated to avoid trees.... there is even the comment "no input on right stick"..... there's no mention of trying to fly back or control the aircraft...... no mention of lack of control.
The Mavic Air as all DJI drones don't require GPS at all to fly or to return to take off position..... they just require a pilot that's prepared to fly their drone.
This is a valid point. I admit, when I was in the middle of this -- a drone that, to my mind, just went haywire -- my biggest concern was trying to make sure it wouldn't crash into trees. If you look at the track, it flew straight over trees and was pretty quickly lost to my LOS. I could hear it but couldn't tell precisely orientation or direction.
You bring up a question, though. I was afraid to attempt to control the right stick because I didn't want to exacerbate the problem. I pressed RTH and prayed it would show up... which luckily, this time it did. What would have happened if I attempted to control it via the right stick? In my mind, if it's going upwards of 20 MPH in a random direction, if I press opposite stick, would it simply counteract that other direction and be stationary? Or would it then begin moving in the direction I have indicated with the stick? I base my knowledge of how it flies based on my experience: a stable, stationary platform based on its knowledge of its position then moving according to my input. I assume it felt it was stationary since it had no inputs even while it was veering around in that crazy loop... so would my inputs have been relative to that motion?
Again, first drone, first experience with this. Regardless, I have many things to add to my pre-flight checklist! |
