I've been called "too analytical" before. So then, I got a job where that's what I'm supposed to do. Works great.
IMO, non-commercial operations for anything that doesn't require a type rating should be fine. That would allow things up to 12,500 pounds that aren't turbojet-powered. Come on, you can drive a 26,000 pound vehicle with an additional 10,000 pound trailer with nothing more than a driver's license!
I don't see night or IFR as valid restrictions either. Having those restrictions on otherwise properly trained and qualified people is going to be a detriment to safety.
I think cognitive issues are more likely to cause problems than heart attacks, strokes, etc - Private pilots generally fly <100 hours/year, or less than 1.2% of the time. These major medical events are point-in-time events that are just as likely to occur in the 98.8% of the time someone's not flying, whereas cognitive degeneration will affect someone 100% of the time. If you can't think ahead of the plane, you're dangerous, and you're likely to crash eventually. So, I think maybe more frequent BFRs (AFRs?) would increase safety among older pilots than any medical would.
In fact, I'd go so far as to say that some of the things that require a second-class medical today such as local scenic flights in a 172 or the like should only require a third class medical.
This whole thing kind of reminds me of the title of one of Rick Durden's articles: "
We worry about the wrong things, and it's killing us."
