Flight log - Weird errors

[BraamMavic]

Hi Guys,

Background
So after grounding myself for the first week after getting the Mavic to gain knowledge, I started flying this weekend. Love this toy. It really is a giant leap from my Syma x5c and Syma X8HG ( both of which taught me valuable cheap lessons in manual mode).

I'm currently driving out to a harvested crop field on a friend's farm 50km away from me (South Africa) to do my flying as it is far from all the WIFI and other interference of the City. I feel it to be a safe place (apart from the dreaded power lines) to learn about my mavic, test its functions & build my skills. I generally fly very high to make sure I can't hit anything (140m high) and have flown to 1.2km out over this property.

Question
All is well apart from having trouble calibrating the compass & a few weird warning messages like yaw errors, auto switch to ATTI mode (despite 18 satellites) & a "high wind" warning while the wind was perfectly still.

I have attached the flight log. Only thing I can think is that the high voltage powerlines may have played some role, but I was standing over 150m away from them & flying 140m+ high. I've read up a bit on the matter here:
Overhead power lines | EMFs.info. , but have also seen many videos where people actually inspect powerlines with drones without issue.

Any ideas on what is causing the issues ?

That's interesting since your flight log is showing compass-related error messages. What happens when you try to calibrate the compass?

I didn't attempt another flight after this one, but have calibrated the compass successfully since.

1. Which errors on the log are all compass related ( apart from the ones that SAY compass error )?
2. Also weird that the first compass error is all the way out to the furthest point from home and that the error disappears and comes back at intermittent stages.
3. I presume the red line is the part of thew flight containing yaw errors.

I was referring to the compass/yaw error messages. You can see them here:

I presume the red line is the part of thew flight containing yaw errors.

I'm not sure which red line you're referring to.

I'm not sure which red line you're referring to

Red Line on map between 09m 25s flight time & 10m 12s

The red line is just showing a long stretch of warning messages. You can scroll down to that point in the log I linked above to see the messages.

Thanks for your continued help Msinger. Any guesses with regards to what may be causing the problems ?

Try another flight and see if you're able to reproduce a flight like that with your freshly calibrated compass.
