“The regulators do a great job on keeping everybody safe. One major catch? In the U.S., electric passenger planes are not yet approved for public use. Hybrid and electric engines also require less or no fuel, cost savings that could be passed on to the consumer. “Electric propulsion typically is a few orders of magnitude more robust because there are less moving parts, and therefore it requires less maintenance, is cheaper to operate,” Clarke said. He pointed out many companies are working on electric-powered engines whose limited range could make them a good fit for these relatively short flights. Their engines are also easier to maintain than ones powered by jet fuel. “They’ve recognized that market is untouched,” said Matthew Clarke, a professor of aerospace engineering at the University of Illinois at Urbana-Champaign. These days, roads are more congested. At the same time, the country has 5,000 airports, many of which are underused: Most air traffic goes through only 30 of them. That’s why companies like Surf Air see an opportunity in what’s called regional air mobility. And at the same time, aviation got a little bit more cumbersome,” Riedel said. “And what happened is, over time, you know, cars get better and more convenient, roads get better. It used to be pretty common to fly short distances back in the ’60s and ’70s, said Robin Riedel of the McKinsey Center for Future Mobility. But Surf Air is just one of many aviation companies betting that in the future, those shorter trips are going to be cheaper, more convenient and potentially more sustainable on an airplane. Right now in the United States, the vast majority of these shorter trips are taken by car, according to analysis by McKinsey. The company provides regional flights between 50 to 500 miles and is developing an electric engine to power planes during those jaunts. The aviation company Surf Air Mobility will go public tomorrow on the New York Stock Exchange, in a direct listing.
