IATA Highlights Aviation Fuel Flexibility Amid Supply Risks

Tashkent, Uzbekistan (UzDaily.com) — The global aviation industry is increasing flexibility in the use of aviation fuel amid risks of supply disruptions linked to geopolitical instability in the Middle East, according to analysis by Stuart Fox, Director of Flight and Technical Operations at the International Air Transport Association.

Fox said a possible continuation of the conflict in the region could lead to localized fuel shortages in parts of the world, making more flexible use of existing aviation kerosene types an important tool for maintaining stable air transport operations.

Commercial aviation primarily uses two types of fuel — Jet A-1 and Jet A. Jet A-1 is mainly used on international routes, while Jet A is predominantly used in North America. Both are certified for aviation use but differ in freezing point: Jet A-1 freezes at minus 47 degrees Celsius, while Jet A freezes at minus 40 degrees. This difference is particularly important for long-haul and polar flight routes.

According to the International Air Transport Association, airlines have long managed these differences through operational procedures and additives that ensure safe performance in low-temperature conditions. Examples include northern regions such as Alaska, where ground temperatures can fall to minus 30 degrees Celsius and in-flight temperatures can drop below minus 50 degrees.

Against potential supply pressure in Europe, broader use of Jet A is being considered, as it is produced in significant volumes outside the Gulf region. Industry assessments suggest this could reduce pressure on existing logistics chains.

The International Air Transport Association and the European Union Aviation Safety Agency have issued guidance allowing the use of Jet A in markets where Jet A-1 is traditionally used, provided operational requirements and restrictions are met.

The guidance includes requirements to adapt operational procedures, including accounting for Jet A’s higher freezing point in route planning, as well as enhanced fuel quality control and labeling. It also stresses the importance of clear communication between suppliers, airports, and flight crews.

Experts note that implementing such practices may require revisions to fuel supply contracts and related documentation, but does not present technical difficulties when coordination among stakeholders is ensured.

According to the International Air Transport Association, expanding the use of Jet A in certain regions does not increase total fuel availability but improves distribution flexibility.

In conditions of constrained supply, such adaptability could become a key factor in maintaining uninterrupted global aviation operations.
