The FAA and ZeroAvia have agreed on a certification basis for the 600-kilowatt electric propulsion system ZeroAvia is developing as a key component in its planned ZA600 hydrogen-electric powertrain. On Monday, ZeroAvia announced that the FAA issued the company a G-1 issue paper, which establishes the criteria for certification.

While ZeroAvia designed the electric propulsion system (EPS) for the ZA600, the company is also offering it to OEMs as a standalone system that could work with a variety of aircraft and powertrains, including airplanes and rotorcraft that run on batteries, hydrogen fuel cells, or hybrid systems.
