I gotta say, I was none too sure about ADSB, but since ForeFlight will put traffic on what amounts to a HUD and/or a moving map, AND give audible warnings on Bluetooth, I’ve been seeing a lot more aircraft than I used to. And it very well may have saved me from a high-wing low-wing vertical merge into the pattern scare (if not worse) a few months ago. Given the cost of everything else in general aviation that’s relatively cheap insurance. And yeah, it won’t necessarily pick up everyone out there and you don’t want to get a false sense of security, but it is nice to know you have traffic four miles out and which way to look. It is generally more timely and more accurate than VFR flight following. Being able to see your aircraft position on the approach plate is a plus too for single pilot IFR IMHO.
