I’m a bah humbug on adsb. It’s not going to stop anything. Flying with a friend, we had a Barron oblivious try and hit us with ATC and ADSB. We Volunteered to descend to keep space even though the Barron was the one being told to change heading. Perfect clear day. We saw the traffic 8 miles away and he passed right over our heads like he was aiming for us. We were watching our ADSB and I know he was too because he was going to fly as close as he could because his screen said he was clear. He never looked out the window. Just like people shooting in holes seen on XM weather and finding the have been closed up.
Hmmm...let's see: because you had access to an ADSB-IN display, you knew the distance, altitude, heading, and registration number of an aircraft on a collision course, and changed altitude to avoid the conflict traffic. With the conflict overhead, you complained that he did not look out the window?
Sounds a little like my memorable ADSB-IN incident: on final approach north bound,
to an uncontrolled airport I spotted an aircraft southbound on the same runway on my Stratux equipped moving map display.
I called, and the EMS helicopter pilot explained he was south bound, low and east of the runway.
