Mechanical failure and engine outs will always rely on muscle memory and training imho, but I strongly presume everything else is going to be "Push red button to survive, switching to autonomy."

(Garman SafeReturn is reliant on GPS though, so unsure how it would handle loss of GPS during autonomous operations, I presume silicon photonics for precision dead reckoning as a backup nav input are the future, or perhaps relying on jam-resistant GPS services and/or multiple GNSS providers simultaneously)

As I understand it, most GA crashes are not due to mechanical problems. Human things like loss of situational awareness, loss of control, controlled flight into terrain (CFIT), flying into bad weather, and improper fuel management are much more common.

The problem is things like regulation and litigation have pushed the price of those modern technologies up outside the reach of everyone who isn't filthy rich, meaning the average GA pilot is tooling around in a clapped-out rental C172 from the 80s.

There's nothing inherently unsafe or unreliable about old airplanes. Aircraft maintenance and inspections are very rigorous and evidence based as compared with almost any other mechanical systems you might interact with. I flew a 1949 Piper PA-16 Clipper with a fairly anemic 108hp Lycoming O-235 with auto gas STC. I'd say it was every bit as safe as any other light single engine airplane, so long as you pay close attention when the wheels are touching ground and mind your density altitude.

In some sense it felt safer than the 172 because I could fly a higher, tighter pattern. It was easier to lose a bunch of altitude on final by putting it sideways in an aggressive slip. The 172's small rudder didn't let it get as sideways, so it was a little more constrained. The 172 did have functioning instruments and dual radios, not just a handheld. It also had flaps. I think it was probably 10-15yr newer? Still a relatively "old" airframe. I probably had 5x or more as many hours in the Clipper so all that could just be biased towards familiarity.

Point being, old plane does not mean unsafe plane. It's not like you're riding around in some rusted out hooptie in the sky. There are rigorous mandatory inspections and maintenance schedules for every single component, which results in mechanical failures being really rare even in aircraft that are nearly 100 years old.

None of that obviates the need to know what you're doing, of course. The pilot in command needs to have control of the plane. I'm pretty skeptical of systems that kind of try to smooth over that sharp edge, I can understand the altruistic motivation behind it, but there's likely a side effect of reducing the perceived risk. That's a problem, because it makes people complacent. So in terms of overall safety, it might not be a win? You're trading on average higher complacency and lower situational awareness for maybe some better outcomes in rare situations? Probably not the best trade.

That stuff just seems awfully gimmicky to me. I'm glad it worked and saved some lives. I don't think I'd want that system in my plane, though. I just wouldn't be able to trust it.

But I also wouldn't want anything to do with the new glass cockpit stuff, way too easy to just lose all your instruments at once. I'll take properly maintained, independent mechanical or electromechanical systems over digital ones every time for things that actually need to work.

Digital systems always seem to accumulate tons of complexity ("features") rendering them extremely brittle. Until we can figure out how to stop doing that, I prefer to avoid depending too heavily on them for important stuff.

The Cirrus parachute system seems pretty simple and trustworthy, that approach feels more directionally correct. Not much more complex than an automotive airbag.
