The aim of this work is to simulate operating process in the aircraft fuel systems, with consideration of external influencing factors. The authors propose a new technique of simulating fuel consumption from fuel tanks during the flight along the trajectory and maneuvering; this technique is based on application of CAD systems and a specially developed finite element FuelTanks solver. The efficiency of this method was demonstrated on a specific example; calculation results were confirmed experimentally. Application domain for the developed method and mathematical software is a wide class of aircraft pneumatic-hydraulic systems along with ground systems which use pressure feed systems. Further development of the work presupposes software product development that follows the whole cycle of creating pneumatic-hydraulic systems from front-end engineering to diagnostic engineering during the operation.
