It operates on the basic input data of weight of remaining fuel, vehicle roll angle, and vehicle pitch angle.  The simulation is accomplished by way of a finite element analysis on the cross sectional area of the fuel tank to evaluate iterative later and vertical c.g. drift, followed by a complete c.g. determination based on coordinated &quot;&quot;stacking&quot;&quot; of cross sectional mass properties elements.  Cross sectional area of the subject fuel tank are defined by a two dimensional array within the software.  Array elements occupied by fuel in a full tank are active, while elements occupied by air, structure, or obstructions are inactive.  This allows changing the cross sections within the tank by changing the &quot;&quot;active&quot;&quot; elements of the cross sectional matrix.  IMMP provides accurate and cost effective mass properties input to aerodynamic flight simulations for the purpose of operational and technical evaluations of aircraft performance.</style></abstract><work-type><style face="normal" font="default" size="100%">12.
