PROBLEM TO BE SOLVED: To provide an unmanned helicopter designed to prevent lodging of crops cultivated in a non-spraying region in the unmanned helicopter spraying a chemical in a prescribed spraying region and, on the other hand, stopping the spraying of the chemical in the prescribed non-spraying region. SOLUTION: The unmanned helicopter 1 comprises a control computer 10 which detects the position, flight speed and flight attitude of a helicopter body through a position sensor 2, a speed sensor 3 and an attitude sensor 5, compares the detected flight speed and flight attitude with the flight speed and flight attitude required in the stored non-spraying region and determines whether or not the helicopter body approaches the sky over the non-spraying region after a prescribed time and the flight speed and flight attitude of the helicopter body during the approach are below the flight speed and flight attitude required in the sky over the non-spraying region. When the helicopter body is determined to approach the sky over the non-spraying region after the prescribed time and the flight speed and flight attitude during the approach are determined to be below the flight speed and flight attitude required in the sky over the non-spraying region, the helicopter body is accelerated to the required flight speed and lifted to the required flight attitude.
