Abstract
[Object] To provide a technique for reducing the fluctuation of an airplane when an airplane enters turbulence without using prior information of two-dimensional or more airflow vectors. [Solving Means] A system includes: a measurement unitthat emits electromagnetic waves toward a planned flight direction of the airplane, receives scattered waves of the emitted electromagnetic waves in atmosphere, and measures a remote wind speed in a radiation axis direction of the emitted electromagnetic waves based on a Doppler shift amount of a frequency between the emitted electromagnetic waves and the scattered electromagnetic waves; a spoilerthat controls a lift of the airplane; and a control calculation unitthat calculates an angle of attack with less lift inclination and calculates an angle of the spoilerthat controls the lift so that the lift does not change when it is determined that the airplane will receive a gust, based on a measurement result of the measurement unit
