In all cases, the most recent issue of relevant specifications applies to the product supplied.Ġ.10 Max. The fuel models for Jet-A1 and neat SPK were mixed together to generate the 50 blend SPK. 91-091 has a lower max limit for acidity and additional requirement for conductivity. Table 3: Properties of neat SPK alternative fuel model.

DEF STAN 91-091, and the JIG (Joint Inspection Group) Aviation Fuel Requirements for Jointly Operated Systems (Check List).

corrects measured API gravity to the standard temperature of 60F. There are other key differences between the manufacturing specification within the United States and Europe/Africa/Middle East/Australasia.ĮxxonMobil Jet A and ExxonMobil Jet A-1 meet the requirements of ASTM D1655 Standard Specification for Aviation Turbine Fuels. Jet A-1 must have a freeze point of minus 47✬ or below and for locations outside the United States, this fuel normally contains static dissipator additive. Jet A, which is mainly used in the United States, must have a freeze point of minus 40✬ or below and does not typically contain static dissipator additive. The primary difference between the two is freeze point, the temperature at which wax crystals disappear in a laboratory test. Aviation Fuel in the Times of the CoronavirusĪviation fuel is one of the most essential requirements of flight operations.What Are the Differences Between AVGAS 100 and AVGAS 100LL?.What Are the Differences Between Jet A and Jet A1?.What Are the Main Types of Aviation Fuel?.What Jet Fuel Does Each Aircraft Require?.Jet A and Jet A-1 are kerosene-type fuels. Some of them are frequently confused by the fuel types and specifications! However, not all flight operators are familiar with the different types of fuel used in airplanes. What Jet Fuel Does Each Aircraft Require? What are the different types of aviation fuel? What is the difference between all those types? What kind of fuel do airplanes use? Which is the suitable aviation fuel for a specific aircraft?ĭue to its long experience in providing all types of clean and reliable airplane fuel, iJET answers all these questions and provides a classification of airplane fuel types. In general aviation, there are two main aircraft fuel types, which are AVGAS and Jet Fuel.

Choosing the right aviation fuel for your aircraft depends mainly on its engine type. AVGAS, or aviation gasoline, is used for piston-engine aircraft.
