"With Airhart Assist (that’s what we call our system), you just push a control stick to the right and the flight computers do all those steps to put you into a coordinated level turn."

Somehow I'm reminded of the staggering amount of continuous calculations the onboard computers had to do to keep the F-117 (the aerodynamic equivalent of trying to fly an Egyptian pyramid) from augering in.

It's not just a political problem. It's also a legal one due to the property rights involved.

Somehow we don't seem to face this problem when it comes to building roads.

A road is usable if you build it piecemeal, that's not true of a railway.

Eminent domain means property rights issues for public infrastructure are also political issues.

They become legal issues when those cases go to court (which is what frequently occurs)

Today, airplanes are not great when it comes to their environmental impacts. If we are successful in our bet that we can grow the GA market, we'll have the resources to invest into greener propulsion technology. That space is currently evolving quickly, with hybrid-electric, hydrogen, full electric and others all being explored. So it's in our plans to address that as well.

I didn't want to make a snarky, unabashadly NIMBY comment until I read this response. For every dollar you lower barrier to entry in aviation, I'm going to be calling my local government representatives to raise it back up by two with taxes and fees. The solutions to environmental problems aren't to grow markets with technology we know is bad so we have the money to make it less bad. The solution is to make it so exp…

Sometimes I think this sort of approach is why so many people on the right are sick of global warming. Sure, global warming is a serious problem, but that doesn't mean that taxing things you don't like is wise, fair, effective, or in any other respect a good idea. If you have a problem with emission of gasses with global warming potential, do that, but please do it across the board.

Let's not specifically tax GA planes, ban gas water heaters, and do a bunch of other random minor-ish things that annoy people and don't actually target the problem.

We already have prototype electric aircraft. As battery costs decrease and battery performance improves, it makes perfect sense that aircraft will electrify. The reason for this is economical, not environmental. Electricity is cheaper than fuel, and maintenance for electric vehicles tends to be less than their combustion equivalents. Both of these factors mean that once the batteries become cheap enough, cost per passenger mile will be lower.

If you decrease the potential market for a product, companies will put less R&D into those products. In the US, general aviation is less popular than horseback riding, which is why we're still using leaded gasoline and piston engines.

Instrument-rated pilot (and engineer) here. First - congrats on the launch! I think you're working on an interesting set of components that will prove useful to GA aircraft technology. Bringing fly-by-wire, and lowering the cost of maintenance/manufacturing are both great efforts. That being said, my personal view is that stick-and-rudder control is one of the less critical components to improving GA safety. Everythi…

I live in a suburb near a county airport. I cannot fathom a life with Tesla owners flying over where my kids and I bbq. This idea is great, but people should still be licensed for the real safety protocols e.g. radio and not crashing into others.

I cannot fathom a life with Tesla owners flying over where my kids and I bbq.

The same kinds of people who speed, watch videos, and do dangerous stunts while they drive are going to speed, watch videos, and do dangerous stunts while they fly.

Uber made everyone an amateur taxi driver. AirBnb made everyone an amateur innkeeper. Now the "tech" industry wants to make everyone an amateur pilot?

No thanks.

I was shocked when learning to fly how much GA tech was stuck in some weird pre-World War II era state. Everything seems so needlessly complicated. Even small aircraft cost so much that I couldn’t imagine a computer controlled system and fly by wire would be cost prohibitive. Even a new C172 is close to $400k at the low end, and anything you’d actually want to fly is much more. A few grand in electronics seems worth…

I would only add that if people have an interest in aviation then gliding is a fun gateway, and relatively inexpensive. As a student it felt like a lot of money (an aerotow might cost 40-50 pounds), but a year subscription to my old airfield cost about 1.5 hours of powered instruction time, flying is cheap on top of that.

You get very good at understanding how an aircraft handles and I like the club aspect. It's really more of a sport than a utility activity, but a lot of glider pilots go on to get PPLs (and a lot of instructors and competition pilots are retired airline or military because they love it so much).

Aircraft cost is in the range of a luxury car, $400k would get you a top end racing glider. You can pick up used aircraft for much less.

Burning fossil fuels is the problem. We can argue until the cows come home about things like plastic straws and bags, but the fact is that burning fossil fuels is rapidly destroying the planet and no amount of burning is sustainable. Banning that is table stakes.
