Katoomba is where I always seem to get closest to other aircraft. One time my ADSB picked up an aircraft, even Sydney Centre called out the other aircraft who did not change his path or speed at all. I did both.
Another time a RPT was inbound to Dubbo and it gave me plenty of time to plan and prepare. The radio was my only other means for lookout. Having aircraft appear on my EFB adds to the prep. I still see planes outside the window but more often I see them on my EFB.
Haven't tried that since I now have a solar panel plugged into the plane in the hanger. Maybe I should test it since winter is coming and the Jabiru isn't great to start in the cold.
But the early adopters help fund the better technology in the future. It's still early days, cars are starting to see major changes. Aircraft will be slower to change but I'm sure it will happen.
I like doing it because besides the basics, he puts me through my passes with many different scenarios and I am pushed. I love it. As XAIRVTW said, doing it my own aircraft is good for familiararity.
I test flew the 170 and the 230 and ended up choosing the 230. I fly mainly on my own but it just feels like a much better and powerful plane when I do my cross countries. I call it my station wagon.
