Propulsion refers to the generation of thrust necessary to move an aircraft through the air. This discipline encompasses a wide range of technologies, including turbine and internal combustion engines, electric and hybrid-electric propulsion systems, and high-speed (supersonic) concepts. It also addresses emerging innovations such as hydrogen-fueled aircraft, ensuring that safety, performance, and certification standards are rigorously met across both conventional and novel propulsion systems.

Discipline leadership supports the evaluation, safe integration, and operational oversight of various propulsion technologies. This includes collaboration on an international scale with industry partners, government agencies, standards development organizations, and academic institutions. It also drives the advancement of FAA policies, guidance, and certification programs. Key efforts in this discipline involve assessing the readiness of emerging propulsion technologies, defining safety and operational requirements, and promoting best practices that enhance system safety and reliability throughout the entire lifespan of the aircraft.
