my personal guess is that this is going to lead to STCs that allow the installation of diesel engines as replacements for avgas engines. They're saying it's going to raise fuel by 40 to 80 cents (USD), so it'll probably be more than that. One of the pluses of AVGAS engines is that they can be overhauled repeatedly which saves on engine replacement costs over the life time of the plane. But the increase in fuel price is likely to bring it level with the replacement cost of a new diesel engine. Since diesels can run JET-A fuel, which is a global fuel source and much cheaper than AVGAS.. I just don't see how AVGAS engines survive in the long term. (older planes can't just adopt an electric engine. batteries are too heavy and the airframe won't be able to carry batteries that provide 600-800nm of range)
