> 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).
