What are the differences between aviation fuel types! ✈ JET A1 – AVGAS 100LL – UL 91…
Depending on the aircraft’s propulsion type (turbines, piston engines), there are different types of fuel:
AVGAS 100LL & UL91 – Aviation Fuel
Aviation gasoline is intended solely for small aircraft equipped with piston engines.
AVGAS (Aviation Gasoline) is one such example: several versions exist, but the most common in France is 100LL.
MOGAS, similar to automotive gasoline, is less expensive but has a higher lead content, requiring more frequent oil changes in aircraft. MOGAS can be used in aircraft equipped with a catalytic converter.
100LL is identified at airfield fuel stations by its label with white lettering on a red background. This strong identification is intended to avoid any risk of confusion with AVGAS UL 91 and JET A-1. Similarly, AVGAS dispensing nozzles are painted red, while JET A-1 nozzles are painted black.
UL 91 avgas is an unleaded aviation gasoline (“UL” stands for Unleaded) specifically designed for ultralight aircraft. This fuel contains no alcohol to protect fuel tanks and systems, unlike SP95-E10 or SP98-E5!
JET A-1 Kerosene & JET B
This is the most widely used fuel for all aircraft with turbine engines (turbojet and turboprop).
This is the most widely used fuel for all aircraft with turbine engines (turbojet and turboprop).Several types of civilian kerosene exist:
JET A-1: This is the most recommended fuel for jet aircraft. Its ignition point is above 38°C and its freezing point is set at a minimum of -47°C.
JETB: This is a mixture of kerosene and gasoline, primarily used in cold environments with a freezing point around -60°C. The use of this fuel is declining.
For specific operating requirements, there are also military versions:
JP-1 to JP-7: These seven fuel versions were developed to meet the diverse needs of military aircraft, which can fly higher and faster, thus requiring a very high ignition temperature and good temperature stability.
JP-8: This is the most widely used by the US military and is similar to JET A1.
Kerosene is primarily used for its high calorific value of 43.15 MJ kg−1 for Jet A1, which allows for a reduction in the total weight to be carried while maintaining a constant range.
