ATEA redefines regional air transport in the hybrid-electric VTOL class, combining low-emission operations, advanced cabin design, and versatile performance tailored for modern passenger mobility.
Its flat floor and modular interior allow fast conversion between two layouts: a premium 4-passenger business version, a 4-passenger economy setup with cargo space. The spacious cabin, wide dual sliding doors, and low step-in height ensure quick, easy access and efficient boarding.
Large windows along the fuselage and cockpit provide a wide view, while extra glazing on the doors enhances light and visibility. Whether flying over cities or natural landscapes, ATEA offers a rich visual experience throughout the journey.
Hybrid thermal-electric propulsion delivers smooth, low-vibration flights with minimal noise. Combined with the rotor, ATEA complies with strict environmental standards—ideal for tourism and urban mobility. It offers a 400 km range with full payload, and up to 900 km with 2 passengers. In addition, baggage capacity is set at 0.5 m³ per passenger (total, distributed).
The ATEA hybrid-electric VTOL is a highly versatile cargo platform designed to meet the demands of modern aerial logistics, from express freight to high-priority technical equipment delivery in urban and remote environments.
Thanks to its flat floor, modular structure and wide rear clamshell doors, ATEA offers up to 3 m³ of internal cargo volume with fast loading and unloading capabilities. The generous cabin space accommodates various freight formats, while the aircraft’s forward access and sliding side doors ensure flexible ground operations in compact spaces.
The aircraft’s hybrid propulsion enables quiet, low-emission logistics missions even in noise-sensitive areas. A cruise speed of 240 km/h and range of 400 km with full payload make ATEA ideal for short to mid-range aerial freight transport. In reduced-payload configurations, its range can extend up to 900 km, expanding mission profiles.
With a payload capacity of 450 kg, ATEA meets the needs of utility operators, logistics providers and public services requiring reliable, clean and cost-efficient cargo transport with a turnaround time of only 15 minutes.
ATEA hybrid-electric VTOL is designed for EMS operations, offering fast deployment, quiet flight and optimal cabin access for urgent medical missions.
Its interior supports one stretcher, up to three medical crew and essential equipment. A flat floor, high ceiling and multi-attachment rails enable secure setups and easy patient access. Foldable seats allow flexible space usage during in-flight care.
Wide sliding side doors and rear clamshell access enable quick loading, even in tight or unprepared areas. The low step-in height and open layout simplify ground handling in emergency situations.
Quiet, low-vibration hybrid propulsion ensures patient comfort and enables operations in noise-sensitive zones. With 400 km range at full load and a 15-minute turnaround, ATEA is ideal for rapid response, rural transfers and high-frequency medical flights.
