FIELD: aviation.
SUBSTANCE: group of inventions relates to fuel supply systems and methods during operation to the aircraft powerplant. The fuel supply system comprises a fuel pipe, a pump, located downstream, a pump disposed in the fuel tank upstream, a pressure sensor located on the inlet or near with the downstream pump and a controller. To supply fuel from the fuel tank to the aircraft powerplant, pumps are used located downstream and upstream, respectively, the pump is controlled in case of the absolute pressure drop at the inlet into the pump located downstream or close to it below a predetermined threshold value.
EFFECT: required pressure for fuel supply.
