A computer-controlled aircraft fuel loading management system is disclosed. The system measures fuel loading volumetrically using flow meter devices and gravimetrically using information relating to the density (specific gravity) of the fuel being loaded entered prior to a fuel loading operation, changes in the temperature of the fuel being loaded and stored information relating to the densities (specific gravities) of a number of fuels and changes thereto with temperature which are derived from American Petroleum Institute information. The system automatically computes and displays the distribution of fuel by tank from stored aircraft tank and fuel load distribution information derived from aircraft manufacturer information. The system also converts a total fuel volume as measured by the system to a standardized fuel volume normalized to a given temperature, for example 60°F.

A method of normalizing a volume of fuel transferred from one location to another to a temperature normalized volume comprising the steps of: determining the rate of flow of fuel; integrating the rate of fuel flow during incremental time periods to obtain incremental volumes of fuel flow; computing the density of the fuel which flowed for each incremental volume of fuel flow; computing the weight of each incremental volume of fuel transferred from the incremental volumes and the densities corresponding to the incremental volumes; summing the weights of the incremental weights of fuel loaded to obtain the total weight of fuel transferred; normalizing the density of the fuel transferred to a preselected temperature; and obtaining the normalized volume from the total weight and the normalized density.
