Arma 3 aircraft control/view switch bug?!?

Sometimes I lose control of the aircraft. The mouse control switched to view control from aircraft control, then I lost control of the aircraft. Moving mouse only turns your head around in the cockpit, just like freelook without having to hold the freelook key. I didn't know how that switch was triggered. It just switched itself.

Sounds like you might've double tapped Alt, which toggles freelook on and off.

As mentioned above, the hotkey for toggling Freelook is double-tapping alt, this is most likely what you are doing unknowingly.
