IIRC, there isn't even enough demand there to switch away from leaded fuel.
- S201 3y agoIt's not that there's not a demand for unleaded avgas, I'd say most GA pilots are ambivalent to leaded vs. unleaded fuel; they just want whatever makes the prop spin. The issues with the unleaded avgas rollout are purely bureaucratic. The FAA has been dragging its feet for literally decades to get it done. Even when we have fuels like G100UL approved which is a drop-in replacement for ~80% of the GA fleet, it still takes forever to get across the finish line.
- histriosum 3y agoIndeed. G100UL is drop in for the entire piston GA fleet, though, not 80percent.
- sokoloff 3y ago> the entire piston GA fleet All the spark-ignited piston fleet, but not the diesel piston fleet (which cannot use G100UL [nor is it needed for them as diesel is already unleaded]).
- cjrp 3y agoAren’t they using Jet-A anyway?
- sokoloff 3y agoIn practice: yes; kerosene (Jet-A) and auto diesel are very close compositions, with the former flowing better at low temperatures (as might be found high in the atmosphere). Jet-A comes out of convenient pumps already located on airports. They’re part of the piston GA fleet for which that fuel is not approved (and neither safe nor needed).
- tinus_hn 3y agoWhy would there be a demand for solving someone else’s problem, when you can just say ‘it’s aviation, change is too hard’ and people will eat it up anyway.
