Abstract: The calculating of mass characteristics of fuel in airplane is a difficult and complicated task. This paper solves the problem of describing the shape of tank by subdividing the tank shapes into tapered boxes, and uses the slice method to calculate the mass characteristic. The problem of how to design the ordering of provided fuel in condition of given limitations to the centre of gravity is solved. The results of example prove that the method of this paper is reliable and useful.

Key words: fuel system, mass characteristic, design of provided fuel
