As developments in the evolving Advanced Air Mobility (AAM) space gradually continue, the market for passenger Vertical Takeoff and Landing (VTOL) air mobility is bifurcating into:
- All-electric “e-VTOL” aircraft. Electric motors powered by batteries, providing lower noise and zero direct emissions, with accompanying range limitations.
- Hybrid-electric “he-VTOL” aircraft. Electric motors powered by a combination of generators driven by a turbine or piston engine, and batteries, enabling long-range, high-speed, all-weather operation.
While there are a few hydrogen fuel cell aircraft under development which promise longer flight times and range, the ecosystem required for wide deployment of…
