Ascendance began final assembly of the full-scale ATEA in early 2026 and targets a piloted first flight in 2026 and certification in 2029. As of 25 September 2026 no first flight has been confirmed and no regulator milestones are public.
Complete ground testing and fly the full-scale ATEA prototype, then establish a regulator-verifiable certification basis.
ATEA is Ascendance Flight Technologies' hybrid-electric VTOL for one pilot and up to four passengers, aimed at regional passenger, medical and defense missions. It can also take off and land conventionally.
The program is in prototype assembly; performance figures are manufacturer targets.
Eight electric lift fans are embedded in the wings, and propellers in the nose and on the vertical tail provide forward thrust; nothing tilts. The STERNA hybrid system uses batteries for take-off and landing and a fuel engine for cruise, with Jet-A1 or sustainable aviation fuel.
Ascendance publishes 400 km range with a full load and 30-minute reserve, and up to 900 km with reduced payload.
In February 2026 Ascendance began final integration of the hybrid propulsion system and avionics in Toulouse after composite-structure completion by Duqueine, citing more than 500 hours of propulsion bench testing. FlightGlobal and Aviation Week reported the start of final assembly in March 2026, with a piloted first flight targeted in 2026.
At Farnborough 2026 Ascendance announced a strategic agreement with ATR on hybrid-electric propulsion integration.
Ascendance positions ATEA for regional passenger transport, medical and defense missions. No firm orders were verified.
The aircraft has not been confirmed as flown. The certification basis, regulator milestones and production plan are not public; published range, noise and emissions reductions are targets.
