PS: Based on two recent alleged "loss of separation" incidents (an interesting concept in Class G, VFR/VMC) with at least one ADS-B IN equipped aircraft, I think we have seen a portent of the future, a mid-air in the circuit, because one of more pilots were looking at their ADS-B IN, instead of "looking out the window".
Leaddie, that future is here now, I call it "device fixation" and I see it most times I do a flight review. Pilots, it seems, mostly private pilots, are addicted to their devices so much that they look at them more often than they look outside. Given the current fixation with devices in the general population, I guess it is not that surprising but it is a bit of a worry.
