Little known fact. Airplanes still use leaded fuel. I’ll bet that the blood levels for all of these families are elevated. Not a great place to raise a kid.

Clarification: Only piston aircraft require leaded fuel. Which is unfortunately a pretty big part of the general aviation market, but similarly sized turboprops do also exist (though are more expensive) and it doesn't apply to modern commercial aviation at all.

Further clarification: Only gasoline powered aircraft without the Auto Fuel STC require leaded fuel.

Although, there is an initiative underway to fully phase out leaded avgas. G100UL is the FAA approved formulation. Exciting time and long overdue.

There are also some plans in the works to fully end leaded avgas in the 2030s.

No, G100UL is still going through the FAA approval process. But it's been approved for many specific engines already, but the majority still aren't allowed to use it. For a full FAA approval we could be waiting another 6-9 years.

The Next big problem is availability, which will only come with time. There are only a few airfields around that stock the fuel. (And from what I can tell.. none that are here in Australia)

"FAA approved STCs for the use of G100UL in all general aviation piston airplanes in September 2022"

Interesting, now I guess we need general availability and maybe a ban on leaded fuels. Still gonna take some number of years before that happens, especially given the vast majority of oil companies don't really care all that much.

Also now the FAA approved it, we just need every other agency in every other country to also approve it, should be a lot easier to do so now the FAA has and has the test data to offer.
