The Propulsion Systems discipline includes turbine and reciprocating engines, electric and hybrid-electric propulsion systems, and high-speed (supersonic) propulsion systems. 

The expert for this discipline works to retain and strengthen U.S. leadership in research and knowledge related to engines and propulsion systems. This includes evaluating the readiness of emerging technologies, shaping agency policies, and promoting the adoption of the most safety enhancing operational requirements and practices into the FAA’s regulatory and certification programs. 

Dr. Catalin Fotache is FAA's Chief Scientist and Technical Advisor for Propulsion Systems. He can be contacted at catalin.g.fotache@faa.gov.
