This is true only for planes that burn fuel. There are about to be a lot of new planes entering the market that don't burn fuel but have batteries and will charge from any usable power source. I.e. mostly renewables given the price of everything else. Basically think flying bath tubs with batteries, propellers, and some fancy fly by wire logic. They are not that hard to build. There are already several flying and flight proven prototypes. Several are in advanced stages getting certified, and factories that will produce these things are being built and financed. The big bottleneck (in the US) for this is the FAA and its certification bureaucracy. This will go from very small volume production now to mass volume production by the tens/hundreds of thousands units in the space of a few decades. That's the reason there's a lot of pressure on the FAA to adapt to new realities because they are suddenly in the business of certifying lots of planes that no longer fit their existing rules and are looking at a vast increase in the number of these things. Most of these things are either capable of flying autonomously or at least vastly simplify pilot workloads. You and I could learn to operate these things in an hour or so. Another reason is that the world is bigger than the bit the FAA has jurisdiction over (the US). These new planes are going to be flying in China, Europe, Africa, and wherever and there's a world where the FAA adapts proactively in anticipation of these changes and where they adapt late reacting and responding to general public and politicians asking them WTF is keeping them in the stone age while the rest of the world gets to play George Jetson. A smart policy maker would want to be conservative but not too late to the party here. And a smarter one smells the money and business potential and would want to be an enabler rather than an obstacle. So, right now is a good moment to let startups experiment a bit and and adapt existing rules. Waiting until these things are flying all over China would be too late. This btw. is not a hypothetical risk but actually starting to happen.
