FIELD: aircraft instrumentation engineering; check of mass of fuel in each tank and total mass of fuel. SUBSTANCE: present parameters of fuel level, temperature and dielectric permeability are measured by means of sensors mounted in fuel tanks and characteristic parameter transducers. Level of fuel is measured in at least three points not lying on one straight line. Volume of fuel in tank is determined by its level with geometric characteristics of tank taken into account. Grade of fuel or ratio of different grades is determined in on-board computer by characteristic parameter and temperature of fuel. Density of fuel in tank is determined in fuel parameter driver included in on-board computer by grade or ratio of grades. Mass of fuel is determined in on-board computer by density and volume determined beforehand. Total mass of fuel is found in summing-up unit. EFFECT: enhanced accuracy of determination of fuel mass at spread of temperatures and grades. 1 dwg, 2 tbl
