Overview
Jet A-1 is the kerosene-type fuel used by civil aircraft worldwide. It is produced to strict international specifications, mainly DEF STAN 91-091 and ASTM D1655, and to the Joint Inspection Group (JIG) checklist where required.
BRONCI coordinates Jet A-1 supply for fuel distributors, airport fuel suppliers and aviation fuel resellers. Because quality and traceability are critical in aviation, each cargo is accompanied by a refinery certificate of quality and checked by an independent inspector.
