Student pilot in the Bay Area here. I completely agree. My CFI has spent time making sure I understand how to reduce noise impacts of my flying. I live out in the hills which means planes and motorcycles are the only noise intrusions I get on a consistent basis. I wish I could do more for the noise issue as a pilot. As for the lead issue, I had a small crush on an experimental that is being developed. The company is using a brand-new engine that can technically burn mogas (Motor Vehicle Gas) but the wings are constructed such that putting any ethanol in the tank is a severe safety issue. This combined with the fact that 100LL and Jet Fuel (diesel) are usually the only two fuels available, it seems like a lock-in for more lead consumption. While there is some good news in the lead/noise department, it's not taking hold as much as I think it aught to: there are electric trainer aircraft produced now that provide very low operating costs, much less noise and release no lead. Unfortunately, I was reading that the performance characteristics make them a less desirable training aircraft than a Cessna 172 so adoption is slow. Question for parent: I know the FAA's avgas initiative has been around for a while, do you know of any significant progress they have made in the area?
