- duskwuff 3y agoNot for much longer! The FAA has approved a replacement for 100LL, and intends to phase out leaded gasoline by 2030. https://www.faa.gov/unleaded https://www.faa.gov/unleaded
- leetrout 3y agoAVGAS 100LL has half the lead content of AVGAS 100.
- renewiltord 3y agoYeah, regulations are written in blood. Chesterton's fence applies.
- samatman 3y agoWhile this is true, commercial aviation is largely jet powered, and jets do not, and have not, used avgas. They use jet fuel, a blend of kerosene and gasoline. Tetraethyl lead is an anti-knock compound, and turbines don't knock. It's good that it's being phased out, but saying "aviation uses leaded gas" leads people to think that commercial aviation uses leaded gas, which hasn't been the case for longer than most of us have been alive. Turboprops are only 8% of planes flown commercially[0] and the category is dominated by small planes, avgas consumption vs. jetfuel is on the order of 2-4%, as a napkin estimate.
