Aicraft DNA to improve tomorrow
Atea’s airplane aeroshape allows a greater performance in forward flight, reassures passengers and increases the overall safety levels.
(Our technology)
Hybrid electric propulsion
system
A modular and scalable combination of two sources of energy (fuel + battery).
A hybrid-electric aircraft is using a mix of 2 energy sources: electric batteries, used during Take-Off and Climb, to benefit from instantaneous release of high power and optimized engines that can run on Jet-A1, Sustainable Aviation Fuel or Hydrogen tomorrow, for the low energy demanding flight phases such as the cruise.
Atea uses Sterna, our hybrid-electric propulsion system that combines two different energy sources:
The electric battery is mainly used for short, high-power phases such as take-off and landing.
The fuel can be conventional Jet-A1, sustainable aviation fuel and, later, hydrogen, used for cruise flights.
Atea takes off vertically in electric mode using the 8 rotors that are embedded in the wings.
Once at the appropriate altitude, the front and rear propellers - located respectively in the nose and the Vertical Tail Plane of the aircraft - are turned on to provide the aircraft with horizontal thrust.
Atea does not have any titling rotors to avoid maintenance issues and ease certification.
Atea is a plug-in hybrid-electric vehicle.
It can be recharged either on the ground(to minimize the environmental footprint)
or in the air (to maximize versatility and be capable of operating from landing sites not equipped with a charging station).

Meeting Atea
productivity is key
Thanks to its hybrid-electric propulsion system, our aircraft offers unrivaled performance in terms of range and turnaround time. The range is 2 to 3 times greater than the competition, and turnaround time divided by 5.

You have some questions?
We have answers
Atea's main differentiation comes from our unique hybrid-electric system that gives us superior performance in terms of payload-range. The ground operations are also optimized thanks to our plug-in hybrid technology leading to quick turn-around times of less than 15min to maximize the productivity of your operations throughout the day
Atea can perform a variety of missions: passenger transportation, VIP transportation, eco-tourism, cargo transportation, medical emergency services and surveillance.
We designed Atea with operations in mind and to ease its entry into service so no specific infrastructures are required beyond what already exists. We are using conventional vertiports (which are small take-off and landing surfaces comparable to helipads).
Atea will be certified in 2027. We are currently working on the first flight of our lifesize, 1:1 flying prototype scheduled for 2024.
