They can run in regular gas reliably enough for training, they can run on jet-a, they can run on batteries. Anything vital can run on jet-a without any barriers.
Excuses are made because it requires retiring or refitting old aircraft, and people need to be forced to do it. Simple as. I will die on this hill.
> The "satellite" view on most online mapping tools is recorded from a piston aircraft.
It is not. You're thinking of lidar.
Wait, you think workhorse aircraft today can run on batteries?
No, piston aircraft cannot run on Jet-A. That would cause detonation and the engine would quite literally self-destruct within minutes - likely during takeoff when the engine is at highest power.
There's been some trials of battery-powered trainer aircraft. The last I checked, they still don't have enough range to do the "long" cross country that's legally required.
And I assure you it's not because of old aircraft. Some flights schools have fleets of brand new 2025/26 models - all of them still run on leaded avgas.
