Air Clues -Confusion around Fuel Grades
Thanks for the Airclues link Coff
Was very interested in the article on Fuel. Confusion? certainly seems to be.
My memory may serve me incorrectly, and I don't have the DefStan to hand, but: Jet A-1 used to be the equivalent of F-35 (Avtur) - which is F-34 without the Fuel Systems Icing Inhibitor (FSII) and anti-static additive (ASA).
Jet A - is normally only found in the US or Canada
F-34 is the standard fuel you will see around RAF stations and is especially important for use in FJ. Use of F-35 could impose a limitation on the use of the aircraft.
Avtag - is obsolete -
Surprised to see no mention of F-44 Avcat - which is basically F-34 with a lower flash point for use on carriers.
