초록

A method and system for measuring the mass quantity and volume of fuel in an aircraft fuel tank is disclosed. A pressure assembly (124) is disposed proximate the lowest portion of each fuel tank on an aircraft (60), with respect to a wing tank (100). The pressure sensor assembly includes a temperature probe (126) having a plurality of temperature sensors (128) mounted therein at spaced apart elevations within the fuel tank. Also included is an attitude sensor (150) in which are provided a roll sensor (156) and a pitch sensor (160) for respectively determ...
