Those who do not change and adapt get left behind.
'nuff said.
Some of us do not want, or need, ADSB.
Most of you here fly normal planes, Bonanzas, Skyhawks and such and make long cross country's. Some here live on the East coast or SoCal, and some, like me, live in the Midwest where it's completely different and not so congested. For those of you that fly like that, and want the latest equipment, that's perfectly fine, I would probably want all the latest gadgets in my plane too. But I don't fly like that.
I've been in aviation long enough to know that I'm no longer going to do any of that kind of personal flying anymore.
I own a '46 Champ, it's all I can afford, and it's the kind of flying I enjoy and I'm going to be doing it until I retire from flying altogether.
I fly under a Class B veil from a Class D airport and I need a handheld radio for the airports I use. In between airports I always turn it off to save the battery, other wise I don't get home. My operations are different from yours, I'm always aware of battery life, you guys don't have to worry about that.
Does that make me "unsafe or irresponsible", I don't think so. I hardly get over 1,000', I'm out flying for the enjoyment of pure and simple flying, not the travel aspect.
For those of you that think I'm just some old fart who has never learned to use a radio and flew from a farm strip all his life. You're wrong, I fly for a living, I've been to JFK, BOS, SFO, DFW and many others, many times in my career. I've done the single pilot 135 and CFI instruction too.
Aviation on a whole is a wide range of pilots and planes. Not everyone fits into the same category as you. So don't look down on a certain group because they aren't like you. I'll try and do that and you should try that too.
Left behind, I'm all for it. I don't get in a plane to push buttons, turn dials and look at electronic screens, I get enough of that cr*p at work.
Like I said, some us don't need or want ADSB.
