Toulouse-based developer of the ATEA hybrid-electric VTOL and the STERNA hybrid propulsion system, founded by former Airbus E-Fan engineers.
Propulsion Architecture
Hybrid-electric lift+cruise: eight wing-embedded electric lift fans and two propellers, with batteries for vertical flight and a fuel engine for cruise.
Primary Certification Context
Not Yet Normalized
Strengths
Ascendance began final assembly of the full-scale ATEA in early 2026, with the composite airframe from Duqueine and more than 500 hours of propulsion bench testing reported. It targets a piloted first flight in 2026 and certification in 2029, and announced a hybrid-electric propulsion partnership with ATR at Farnborough 2026.

Weaknesses / Open Questions
The full-scale ATEA had not been confirmed as flown as of 25 September 2026. The certification basis and regulator milestones are not public, and range, noise and emissions figures are manufacturer targets.
