Advanced air mobility (AAM), or urban air mobility (UAM) as it's sometimes called, is an emerging mode of transport designed to provide aerial ridesharing services in densely populated urban areas, allowing passengers to fly over ground traffic and more quickly reach their destination. The service will provide transport intracity, city-to-suburb, city-to-airport, and city-to-town. Aircraft for this market are electric vertical takeoff and landing (eVTOL) craft, are piloted, and typically seat 3-5 passengers. There are several OEMs developing aircraft to serve this market, but only 20 or so have the capital required to succeed. Most OEMs anticipate entering aircraft into service in the 2025-2028 window.
