First time this has happened after 10 months of flying. I have a MM and it was connected to a new iPad mini. All was well for the first 5 min or so then the screen suddenly went Blank. I was flying VLOS and had no problem bringing it back and landing, but this really rattled me having the screen disappear like that. As a side note before i left the house I made sure the cache showed the map function, and at first that was reflected on the screen. That after a min or so went to a green screen as it sometimes will do but knowing I was to fly VLOS I went ahead with the flight and then the blank screen. WHY did this happen??
