Patent attributes
An apparatus for testing an aircraft tank system includes a fuel supply device including a fuel reservoir, a fuel supply line for supplying fuel from the fuel reservoir to a fuel outlet of the fuel supply device, and a first isolation valve disposed in the fuel supply line. A fuel transfer line transfers fuel from the fuel outlet of the fuel supply device to the aircraft tank system and a second isolation valve is disposed in the fuel transfer line. An electronic control unit (ECU) of the apparatus is adapted to control the first isolation valve and the second isolation valve so as to interrupt the supply of fuel through the fuel supply line and the transfer of fuel through the fuel transfer line, respectively, in response to a test parameter signal provided to the electronic control unit (ECU).
