It's really hard to know what to do when someone's showing on the iPad at your 6 o'clock, same altitude, and you don't know if he sees you--and you can't see him for whatever reason, but mostly that God didn't put eyes in the back of heads. That was exactly my scenario yesterday. I had just left Fort Collins/Loveland (KFNL) where the student helicopter traffic was like the local beehive, along with quite a bit of fixed wing traffic. As I took off on 15, which everyone was using because the wind was from the south, a "furrin" helicopter announced that he was on final for 33--apparently paying no attention that 15 was the "active" runway--yeah, he was legal (there is no "active" at a non-towered airport), but stupid. Had I not turned out as soon as I saw him, I wouldn't be writing this, because obviously he was concentrating on either shooting the ILS or just coming in to land, but not on oncoming traffic (and yeah, I did announce departing on 15).
So I was super happy to go back to Greeley (KGXY), anticipating a more relaxing environment. I climbed up over the buzzing bee student helicopter traffic, which seemed to be congregating along I-25 which is just east of KFNL, leveling off at 7000'. The "active" at KGXY appeared to vacillate between 35 and 10, mostly 10, so I decided to fly north of the airport and past it to the east and do a right descending turn to a 45 to downwind to 10. From 7000' to 5500' (TPA), I let the speed build up, and as I lined up on the 45 to downwind at 3 miles out, a Skylane called in to say that he was on the 45 to downwind, 3 miles out, also!
But because both of us have ADS-B Out, I could see his tail number on my iPad, and he was actually about a quarter mile behind me, and 200' below. My guess is that he "saw" me on his iPad or on his ES transponder, as I'd seen him. I announced that I was (by then) 2 1/2 miles out on the 45 to downwind. I kept up my speed, as obviously a Skylane is capable of going faster than my airplane. When I turned downwind, I announced that I was on downwind, and the Skylane pilot announced that he was on the 45 "with downwind traffic in sight". Whew! Now I was much more comfortable--he was less likely to run me down, as I slowed down on downwind. For courtesy, I made a short approach anyway, clearing the runway just after he announced turning final.
Now let's imagine how this would have played out, had neither of us had ADS-B Out. Neither of us would have seen each other. When he called in at what appeared to be the same place I was, we would have had to have some conversation about where each other was. Or perhaps one or the other of us or maybe both of us would have had to break off our approaches, for safety.
So yeah, technology is a wonderful thing, and perhaps as we all get more accustomed to using it, it will reduce the concerns about the "big sky" not being quite so big after all. The thing we have to be careful about is relying on it too much, and spending too much time looking at screens instead of out the windshield. Hearing the verbal traffic announcements from the ES transponder and Foreflight/Stratus 2/iPad combination aids in that, but it's still a pilot responsibility.
