摘要：The commercialization of air taxis and autonomous passenger drones will one day congest urban airspace. Operators expect that, once flights are autonomous and the cost of service falls, high-traffic urban “vertiports” could see hundreds of air taxi takeoffs and landings per hour. Low-altitude airspace—between 200 feet and 5,000 feet above ground level—offers a relatively blank slate to explore new regulatory models for air traffic management and avoid command-and-control mistakes made in the past in aviation. Regulators’ current proposals would centralize air taxi traffic management into a single system to coordinate air taxi traffic, but this approach likely creates technology lock-in and unduly benefits the initial operators at the expense of later innovators. To facilitate the development of the air taxi market, regulators should consider demarcating aerial travel corridors and auctioning exclusive-use licenses to operators for use of those corridors, much like regulators auction radio spectrum licenses and offshore wind energy sites. Exclusive rights to routes would allow transfer and sale to more efficient operators and would also give operators the certainty they need to finance the substantial capital investments.
