Error in flight

[Englishbloke]

Hi,

Any advice on this please...

Warning: Inflight, Working compass encounters magnetic field interference, please switch to ATTI mode of aircraft behaves abnormally.

The app isn’t asking me to calibrate anything. This error only occurs during flight, it’s been at a reasonable altitude each time (30m+). No errors before take-off. Rural location.

Cheers.

Any power lines/pylons in sight of your flying area. Also farms often use electric fences to restrict animal movements.

Yes, power lines in the field.

Thanks.

That's most likely the source of your interference I would say..
