Aviation uses two very different fuels. Supplying the wrong one, or a contaminated batch, is a safety issue, which is why aviation fuel handling is among the most tightly controlled activities in the petroleum industry.
Jet A-1
Jet A-1 is a kerosene-type fuel used by turbine engines: jets, turboprops and turbine helicopters. It is produced to international specifications such as DEF STAN 91-091 and ASTM D1655, with a low freezing point suited to high-altitude flight.
AVGAS
Aviation gasoline is used by piston-engine aircraft. The most common grade, AVGAS 100LL, is a leaded, high-octane fuel produced to ASTM D910 and coloured blue for identification. Its user base — flight schools, general aviation and agricultural aviation — is small but demanding.
Why they cannot be mixed
Putting Jet A-1 into a piston engine, or AVGAS into a turbine, can cause engine failure. Airports therefore use distinct colour coding, nozzle types and handling procedures for each fuel.
Quality and documentation
Aviation fuel passes through a documented chain of custody from refinery to wing, with sampling and testing at each stage. Operators should expect a certificate of quality for every batch and clear traceability.
