Guys, its me again, this is what I know so far, my MA will take off only if I turn it on under a roof (or as soon as I turn it on and pairs with my remote I take off) so it will fly on vision mode only once flying I can fly it outdoors and wait for it to get GPS signal and I will be able to then yes fly it wihtout restrictions, this is so far the only way I'm able to fly my MA since I traveled to Argentina from NY.
As I posted https://forum.dji.com/forum.php?mod=redirect&goto=findpost&ptid=133778&pid=1397212 even with my compass signal in green the calibration fails, doesn't matter if I have my Apple watch far away or any other electronics, event he remote control with my iphone its far away and still the calibration fails. From what I've seen so far this doesn't look like a man error, why I say this, cause before coming to Argentina (South America), I was living in NY and flew my MA there multiple times, most of those times in the city where for sure there are more cel and WIFI antennas that could cause interference and it even never asked me to calibrate the compass like it happens here in Argentina.
I tried to edit my post, but it did not allow me, so here is my more complete reply:
Thank you for bringing this up. Yes, my Mavic Air was never able to calibrate compass while in Brazil.
Now, to defeat the south hemisphere thesis I recently took it to the Marshall Islands which is above the equator. Again, the Mavic Air was never able to calibrate.
I did fly it twice, kind'a sneaking it through the initialization process as the AC just starts to communicate with the base, the took button appeared and I went for it, and it took off without recording the home location and without GPS and without needing to calibrate and it flew normally. It happened at different locations in the atoll (one urban, just very close to the wall of the hotel, a three-story building, the other at a remote beach at the very end of the atoll, 25 miles away from the other location).
These two successful attempts represent a 2 out of 15 attempts to fly. And on both cases when it landed it required a compass calibration and I was not able to make it happen again, even trying to do the sneak process again.
I know people here try to imagine it is first an operator error, or that it is the watch, or this or that. I'll say no to those because I've flown close to 100 times a Mavic Pro and the Mavic Air (I have both drones) and I never crashed.
Both Brazil and the Marshall Islands, where the phone system is different, and using an American phone (Apple 6S and Apple 5S) my Mavic Pro had no problems. Using the same phones, the Mavic Air has issues. I have flown the Mavic air in California and Oregon, no problems, and both locations were hundreds of miles away from my home where I fly the Mavic Air and Mavic Pro for test purposes only, do the updates, before going on trips.
I do think it is a Mavic Air issue and I do think it could be related to the phone communicating to the RC (plugged) when the phone is away from the United States, or something with the Mavic Air’s calibration process itself when in foreign land. At least this is my case, for my Mavic Air.
BTW, I just flew the Mavic Air, first time now that I’m back from the Marshall islands. First it was saying “there is no image transmission signal”. But it updated the home point, and gave me the take off button. But It required calibration, but no message appeared on the screen about it, but when going to the menu, it was there, overall status had a red triangle with the exclamation point, and the calibration needed was there with its yellow triangle with exclamation point. So I turned the AC off and on and calibrated it, it still said no image transmission signal. So I turned the RC on and off, same issue, no image transmission signal. Turned the AC on and off one more time and voila, this time it worked. Took off and flew no problems.
