Patent ID: 8571726

Claim:
A method for calculating an aircraft fuselage leakage calculation of an aircraft, the method comprising: determining a calculation period for an aircraft fuselage leakage value and inputting the calculation period into a computer to obtain a first input data; obtaining one or more outside air inflow rates and inputting the one or more outside air inflow rates into the computer to obtain a second input data; obtaining one or more air outflow rates and inputting the one or more air outflow rates into the computer to obtain a third input data; accumulating the first input data, the second input data, and the third input data in the computer to obtain an accumulated input data; processing the accumulated input data with a process software to obtain an output data in the form of a calculated aircraft fuselage leakage value; sending the output data to a data file; and, using the calculated aircraft fuselage leakage value to calculate an aircraft fuel savings potential value, wherein the method communicates the aircraft fuselage leakage value and an increase in a fuel consumption rate due to an additional amount of outside air inflow required to replenish air loss due to fuselage leakage, due to aerodynamic drag, and due to reduced thrust recovery.
