God these DJI drones

[Meta4]

Fair enough. But I never had that issue with my A2s and I've used the truck as a launch pad since I first started flying. I'll have to check but I'm pretty sure when it happened before, the drone was sitting in the driveway. Memory could be failing though. I'll see for next time. Thanks.

Next time you see it .. check the message closely.
It used to say Calibrate compass or move aircraft .. but no-one notices the second part.
If you switch off and move away and have no problem there, that shows that there was nothing wrong with the compass and the issue was the spot you put the drone down.

Your tonneau cover may be aluminium, but the truck isn't.
There would have been plenty of steel nearby and changing position by an inch or two could be the difference between seeing the warning and not seeing it.

It's most likely that there was nothing at all wrong with the drone's compass.
It was working normally and warning you of magnetic interference very close.
DJI's warning is very badly worded and recalibrating the compass cannot possibly fix the issue of being close to a source of magnetic interference.
Almost any time you see that warning, the proper action is to switch off, move away from the magnetic interference and start again.

My tonneau cover is fabric. My truck IS aluminum. 20-20 ford f150 . Every time I have had a compass recalibration issue come up, I have ignored it. Usually a reposition of the drone is all that is needed.

Perhaps the bodywork is ... but what about the chassis and engine block?

Possibly, but I haven't had that issue Normally, if I have a compass issue, it's due to a larger area of concern, ie environmental issues, ie rebar in concrete or high concentration of iron in soil. I havent had the recalibrate issue since the air 2
