Abstract: An object of the present invention is to provide a method for preventing turbulence-induced accidents that can expand a detection range to about 20 km without increasing the size of a device or increasing the energy consumption, can perform planar distribution monitoring of turbulence when the turbulence is detected in the flight direction and also can output a signal for autopilot steering input that decreases the fuselage shaking when the turbulence is difficult to avoid, as well as to provide a device having those functions. In the method for preventing turbulence-induced accidents according to the present invention, an optical remote airflow measurement device of a Doppler lidar system using a laser beam is used to routinely enable distant turbulence to be detected by fixing a laser emission course in a flight direction and taking a long integration time of a reception signal, and to enable planar distribution of the turbulence to be displayed when turbulence is detected, by scanning the laser emission course in a horizontal direction and switching an image display to a two-dimensional display.
