Beta Technologies CX300

The ALIA CTOL (CX300) is an eCTOL (electric conventional take-off and landing) aircraft being developed by BETA Technologies. The aircraft began its life as a prototype for BETA’s Alia-250, but after a change in strategy in 2023 it is now intended to go into production. As a result, a prototype version of the aircraft, the SN1, has already flown many test flights since 2020. Its intended entry into service is 2025 and certification is being sought from the FAA under Part 23.

Structure and Powertrain

The structure is essentially the same as the ALIA-250. The CX300 seats five passengers and pilot inside a composite fuselage. The aircraft features a V-shaped tail and a high wing, with two booms stretching between the wing and tail. The landing gear is shaped similarly to skid landing gear but has four wheels fixed to it for take-off and landing. Lift is provided by the wing and propulsion comes from a fixed pusher propeller at the rear of the aircraft. All are independently powered by electric motors, fed by batteries located beneath the cabin.

Distributed electric propulsion (DEP) is the name given to this method of powering aircraft. No critical points of failure provide a high level of redundancy and will ensure safety onboard. Further safety is ensured in the design by having the lift fans positioned above the fuselage and away from passengers.
