You had strong interference it didn't go into RTH but auto landing it seemed to stop landing I expect it thought ground underneath it was not safe for landing, if you had of pushed left stick up this would have cancelled landing but when you went into landing mode you were pushing on right stick, it shows no movement on left stick.
You were in a geo space class C airspace this could have forced the landing, you will be more aware of your area so you can let us know. And what firmware are you on.
Thanks for your reply.
When the connection was lost the first time (strong interference), the mavic automatically went to the home point (red line on the log). The app showed 'returning to home' which I tried to cancel by touching the red x, but the app was unresponsive already. It then started to land. The surface underneath was perfect flat (road) so it could have landed without any problems. The Mavic kept hovering on 2m height however.
I also pushed the sticks into several directions to see if it responded independent from the hanging app, during the red line movement of the log, and also afterwards when it started to hover/ try to land, but it seems that the log did not record all the data. When I replay the log in the app, it suddenly jumps (red line) to the end of the log, and stick input is not shown at all. After the end of the log however, the phantom hovered for at least 1 minute, and I pushed sticks into all directions, I tried to use the touchscreen of the app, and finally I pushed the pins to the diagonal down opposite directions for an emergency motor stop. All of this stick input is not shown in the log, since it happened after the log ends.
The display of the remote said something about stick calibration error during these emergency stop push actions. After all this, I decided to hold the mavic and remove the battery...
I know this is a class C airspace. I have flown (with caution) many times (20+) around this area. The drone has never returned to home because of this.
app version is 4.1.0, firmware 01.03.0700, database 00.00.01.04 |
