Hi,
Flying Mavic Air I noticed that first fly was made @ 2.4 GHz, second one, 5.8 GHz. Third one, again 2.4...

Is it normal? Does it switch itself? What conditions?
CE regulations.

Yes, this is normal when in auto channel mode. It will pick the one with the best signal quality. If you are in an open flield without other WiFi interference it will most certainly stick to 2.4 Ghz. But if you are in a built up area with other WiFi networks around the preferred choice will be 5.8 Ghz.

Useful information, thanks for sharing.

You are welcome and I hope that what I wrote is correct. But this is my understanding how the auto channel mode should work.

You certainly could be correct there as since the last firmware update at the home location I am on 5.8 which until that update I have always been on 2.4 :-)
