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