Less noise, more actions for sustainable aviation.

Less noise, more actions for sustainable aviation.

Aviation has become popular and accessible, connecting the world in record time. It is now time to go further and enter a new era that keeps people strongly connected, but with far less pollution.

It is an extraordinary challenge for the aeronautical and the energy industries, the outcome of which will impact us all. Indeed, the stakes are high for climate issues, but also social, economic and sovereignty ones. The way we face this challenge will determine the future.

Yes, cleaner aviation cannot wait. And the good news is, technological solutions are within reach and can be deployed now.

Hybrid electric is the long-haul flight to cleaner connections. It works today and prepares for tomorrow.

Deep tech pioneers

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.
