Description

Airlines recognize the importance of accurate accounting of jet fuel inventories to ensure reliable tracking of product from receipt to disbursement. To assist in the attainment of this goal, this specification was developed by the A4A Industry Audits Department, in consultation with the A4A Energy Council, the A4A Fuel Technical Committee and the A4A Audit Panel.

With this latest revision, operators can report to fuel inventory position holders on a Net corrected basis within a tolerance level of 0.100 percent. To assist with this effort, this Spec includes an Excel spreadsheet, which provides conversion factors to convert gross jet fuel inventories to Net corrected inventories. The following explanation summarizes the importance of the adjustment: On average, every one-degree variance in temperature above or below 60 degrees results in a five-gallon change in gross inventory for every 10,000 gallons of jet fuel in inventory. Without the correction to Net corrected inventories, variances caused by temperature changes have the potential to mask system leaks, theft, and out-of-tolerance metering devices, among other issues.

To further assist you in your fuel inventory process we have included a second spreadsheet titled – Harmonization. Harmonization of the individual position holders’ gross to net inventories is performed so that both inventories are in the same ratio to each total respective system inventories.

Notes

Spec 123 is provided in a zip file which includes one PDF document with two embedded Excel files. No hardcopies are available.
