PROBLEM TO BE SOLVED: To provide a fuel feeding device for a pilotless helicopter allowing lengthening a flying distance and a flying time and returning always assuredly corresponding to a residual volume of fuel. SOLUTION: This device comprises a main pump P2 adapted to feed the fuel to an engine 1, a main tank 4 communicating with the engine via the main pump, a sub-pump P1 adapted to feed the fuel to the main tank, a sub-tank 5 communicating with the main tank via the sub-pump, a main residual volume sensor 6 adapted to detect the residual volume of the fuel in the main tank, a sub-residual volume sensor 7 adapted to detect the residual volume of the sub-tank, a control device 8 with which the main pump, the sub-pump, the main residual volume sensor and the sub-residual volume sensor are connected, and a communication instrument 9 connected with the control device on the helicopter, and the device comprises an operating device 19 for driving/ controlling the helicopter on the basis of information transmitted from the communication instrument 9 on the ground side.
