Fuel Readiness Level (FRL) table |
CAAFI has developed the FRL table to classify and track the progress on research & development, certification, demonstration activities, and the supply of alternative jet fuels. |

Prescreening of synthesised hydrocarbons intended for candidates as blending components for aviation turbine fuels |
The aviation industry’s evaluation and qualification process for synthesised jet fuel components can be resource-intensive but ensures that any alternative fuel specification is safe, fungible and meets stakeholder needs. This technical guidance document identifies prescreening methods that can provide early-stage confidence to fuel developers on whether Alternative Jet Fuel (AJF) formulations might encounter downstream challenges with the completion of the ASTM D4054 evaluation process. |

SAF qualification overview |
Get an overview of the rigorous testing requirements to compare the properties of new, alternative jet fuels to petroleum-derived jet fuel to determine whether a fuel can be considered “drop-in.” Learn about how SAF gets certified, currently approved fuels and existing standards and approvals. |

KTN Cleared for Offtake - Supplying Sustainable Aviation Fuels |
As the names suggests, SAF must also meet specific sustainability standards. Governments often require suppliers of aviation to meet certain standards in order to qualify them as sustainable. |
