This week, AIN senior editor and FutureFlight editor Charles Alcock give his take on the nine-seat, all-electric eFlyer 800 announced by Bye Aerospace as a more economical and environmentally-friendly alternative to the venerable Beechcraft King Air. He also discusses Bye’s probability of certifying the eFlyer 800 by its 2026 target, as well as the higher-density lithium-sulfur batteries from Oxis that are slated to be employed as the sole power source on the cabin-class twin-prop airplane.
