Home » FAQs » Given that UL94 is available, why not deploy it widely now and switch to UL100 when ready, for faster adoption?

Airport owners/operators, service providers (FBOs) and other stakeholders are free to deploy UL94 as soon as they choose. Airports can pursue support through federal and state grant funding, such as through the Airport Improvement Program (AIP), to install infrastructure for unleaded fuels like UL94. Some states and localities also offer incentives to offset fuel and STC costs, encouraging earlier adoption. FBOs and airports are working together, where FBOs have invested in the necessary infrastructure to implement unleaded fuels. These efforts help facilitate a smooth transition to unleaded fuel now, paving the way for UL100 deployment when it becomes available.
