I think we might see gasoline/jet-A over electric airplanes, perhaps with or without battery storage. That would allow a few neat optimizations. You'd have more control over CG. You could have a smaller high efficiency engine that always ran at peak efficiency (or an IC engine with several modes). You could have more control over noise in urban areas. With a battery for peak/boost power, you could have a tiny engine which could supply cruise plus accessory power and use battery-backed boost for takeoff/climb. Engines that are replaceable in a few hours. All kinds of good things could happen. >Many airplanes are certified for a ramp, taxi, and takeoff weight higher than their approved landing weight. Is that common in G/A aircraft? In any case, I'd love to see a tech. revolution in GA powerplants. I've grown tired of having quaint old 1950's era tractor engines be the dominant technology.
