Essentially hobby aviation is completely stuck in the 1970s and getting the engines modernized would be "cost prohibitive".
Since wealthy people still want to play around in planes they get to rain lead on our heads.
The wealthy are in jets or turbo props which don't use leaded gas.
Then the super-rich can continue to fly, paying the nation for the economic and health effects they're causing, but regular hobbyists will have to ground their planes till unleaded avgas is available.
Should be easy-ish to enforce, because planes and flight plans are registered, and anyone paying no tax and flying a lot ought to be easy to catch.
'Hobbyists' have been waiting for lead free avgas for decades. You should just crush their planes while you are at it.
While the super rich do whatever they want? By the way, if you are super-rich, you are probably burning Jet-A anyway, not AVGAS.
The real fix is to just issue the damn regulation and provide some incentives. Engines have to be overhauled and replaced periodically anyways. Make it easier to recertify aircraft, provide a path for aircraft that no longer have the original manufacturer around. Give incentives for small airports to stock on whatever the proposed avgas replacement is until the demand catches up.
> flight plans are registered
No they aren't. No requirement for flight plans in VFR.
If you are proposing such harsh legislation, you should at least try to learn something about the subject matter.
The industry is rapidly trying to move to do two things, 1. remove lead from the fuel, this is noted by other commenters. And 2. Pushing for more electric GA.
Pilots don't exactly like getting their hands covered in lead when they check fuel, much less dumping it into the atmosphere when they fly, but it's still an unfortunate fact of life. Times are absolutely changing though, and the future looks bright.
Or having their spark plugs fouled by the same lead.
If banning leaded gas leads to qualified pilot shortage, the industry only has itself to blame for failing to train the people it needs.
Lufthansa at least (and maybe most big euro flag carriers?) runs its own “ab initio” training, where it takes non-pilots and makes them into pilots with a job.
Lufthansa has warned cadets they won’t need to hire for a few years: https://www.businessinsider.com/in-crisis-lufthansa-restruct...
Not sure if there’s a shortage of skilled pilots today as flight counts are still down like 20% in USA vs 2019, and generally a sharper decline elsewhere.
