What is Jet A-1?

Jet A-1 is the world’s most widely used commercial aviation fuel. It is a kerosene-type fuel designed specifically for gas turbine engines, including turbofan and turboprop aircraft operating across global aviation networks.

It is defined and controlled through international specifications to ensure consistent performance, safety, and compatibility across aircraft types and operating environments. These specifications govern properties such as freezing point, flash point, and combustion characteristics.

MB Energy’s Jet A-1 is fully compliant with the AFQRJOS Check List. It meets the requirements of Def Stan 91-091 (Issue 11), ASTM D1655 (latest issue), and the NATO F-35 specification. This ensures that fuel quality, traceability, and regulatory compliance are maintained at every uplift.

In practice, Jet A-1 enables reliable engine performance across varying altitudes and temperatures, supporting uninterrupted aviation operations from departure to landing.

Typical Applications

Jet A-1 is used across a wide range of aviation operations where turbine engines are deployed.

Technical Specifications

Jet A-1 is defined by internationally recognised standards that ensure consistent quality and performance across global aviation markets. Its characteristics are engineered for safe handling, storage, and combustion in turbine engines.

Standards and Approvals

Jet A-1 supplied by MB Energy complies with the AFQRJOS Check List and meets Def Stan 91-091 (Issue 11), ASTM D1655 (latest issue), and NATO F-35 specification requirements. These standards define fuel quality, handling, and performance parameters across aviation systems.

Emissions Classification

Jet A-1 is a conventional aviation fuel. Its emissions profile is defined by hydrocarbon combustion in turbine engines. Any emissions performance depends on engine type, operating conditions, and fuel management practices.

Chemical Composition

Jet A-1 is a kerosene-type hydrocarbon fuel composed of a defined range of carbon chain molecules. Its composition is tightly controlled to ensure consistent combustion behaviour and compatibility with aviation fuel systems.

Ignition Quality (Combustion Behaviour)

Jet A-1 is designed for stable and efficient combustion in turbine engines. Its ignition and burn characteristics support reliable engine operation across different flight phases, including take-off and cruising altitude.

Cold Flow Properties

Jet A-1 has a low freezing point, enabling operation at high altitudes where temperatures are significantly reduced. This ensures that fuel remains fluid and usable during long-haul flights.

Storage Stability

Jet A-1 is formulated for stable storage under controlled conditions. Proper handling and storage infrastructure are required to maintain fuel integrity and prevent contamination throughout the supply chain.

How It Works

Jet A-1 supply is structured as a coordinated process from sourcing to aircraft uplift.

Fuel is sourced according to international specifications and delivered into airport storage infrastructure. From there, into-plane refuelling services manage the transfer of fuel directly to aircraft.

MB Energy coordinates supply, logistics, and administrative processes to ensure that fuel is available where and when it is required. This includes managing partnerships, documentation, and operational alignment across locations.

The result is a consistent and traceable fuel supply process that supports uninterrupted flight operations.
