This I know: If you see something with your own two eyes, you probably can avoid it. Happened to me just last month. A regional airliner, working with ATC, was approaching its destination. I was working my way around the Class C airspace, at the center of which the airliner was aimed.

I saw him first as an ADS-B target on my EFIS screen, a simple white diamond with a predicted (that’s important) trajectory, some 20 miles away. I looked up to search for him in my windscreen, even so. I always look up and out, no matter my flight conditions. Here’s why: Closing speeds what they were (around 450 knots), the distance between us closed in what felt like an instant. And there he was, right where I’d guessed and where ADS-B predicted.
