I got this today after flying for about 10 min. Scared me quite a bit, as the status bar went red, the bird was about 300M away over water and I had no idea what it meant, whether I had control or not etc. So I just mashed the home button and thankfully it responded, I landed and after a restart of the app, controller and the I1, the error condition went away. But I'm hesitant to fly again without understanding what the heck happened here. I'm on v.16 and there were a bunch of dialog errors that popped up saying updates were needed, try restarting the aircraft etc etc. Anyone seen this before?
