The invention belongs to the technical field of aviation, and provides a method for calculating the flap adjusting amount during yaw and sideslip of multi-turboprop aircraft in order to solve the problems of yaw and sideslip of the multi-turboprop aircraft. The method comprises the steps that 1, a deflection angle theta and the deflection direction of a steering wheel are obtained; 2, according to a formula, a flap adjusting amount numerical value L is calculated, and K is a flap adjusting coefficient; and 3, the flap adjusting amount L and the adjusting direction are obtained according to the deflection direction of the steering wheel. 本发明属于航空技术领域，为解决了多发涡桨飞机偏航、侧滑问题，提出一种多发涡桨飞机偏航、侧滑时襟翼调整量的计算方法，包括：步骤1、得出驾驶盘偏转角度θ和偏转方向；步骤2、按照公式计算得出襟翼调整量数值L，所述K为襟翼调整系数；步骤3、根据驾驶盘的偏转方向，得出襟翼调整量L和调整方向。
