Understanding Sustainable Aviation Fuel

Zrównoważone aviation fuel is a biofuel produced from resourcable beests such as used cooking oil, municipable solid waste, forestry residues, and energy crops like camelina or algae. Unlike conventional jet fuel derived frem crude oil, SAF can be blended with existing kerosene- based fuels (up to 50% blend approved for commercial use) and used in condicomissions aircraft emplifications.

Te FAA 's authority over fuel quality and d safety is foundationál te adoption of SAF. Under Title 14 of thee Code Code of Federal Regulations (14 CFR), thee agency sets standards for aviation fuel specifications, including ASTM D1655 (conventional jet fuel) and ASTM D7566 (synthetic fuels including SAF).

Te FAA also issues supplemental type certificates for aircraft and engine modifications need ded to use higher SAF blends or new fuel type. As of 2025, ASTM has approved up to 50% SAF blends in commercial aircraft, wigh ongoing test for 100% SAF use. The FAA collaborates with thee ASTM International communictee D02.J on aviation fuels to update these stands ards as new production logies emergee.

Beyond certification, the FAA developers policies that integrate SAF into thee national airspace system.
