CAE's electric Piper Archer stalled at the design stage, exposing the battery physics gap between electric aviation promises and usable training aircraft.
Eviation Alice completed its first flight on September 27, 2022, raising the question of whether all-electric regional aviation can overcome battery physics to serve short-haul routes commercially.
NASA's X-57 Maxwell validated the aerodynamics of a radically smaller wing powered by 12 leading-edge electric motors, shaping how engineers now design the next generation of electric aircraft.
Solid-state batteries could push aircraft pack energy density from 200 to 500+ Wh/kg, but manufacturing challenges mean meaningful aviation use is still a decade away.
The Eviation Alice completed its first flight in September 2022, but battery physics and a long certification road separate that milestone from commercial airline service.
Radio Hangar explores The Rolls-Royce Spirit of Innovation, the Fastest Electric Airplane Ever Flown, and What a Three-Kilometer Speed Record Actually Proves About Batteries.
