    • Method for dynamically limiting the inclinations of monoblock flight control surfaces (FCS) in an aircraft. Dynamic limitation of the FCS is activated if a stall susceptibility condition is detected in the current aircraft environment. The real-time calibrated airspeed of the aircraft, real-time angle of attack (AOA) of the aircraft, and real-time sideslip angle (AOS) of the aircraft are obtained. The aircraft parameters may be obtained via estimation if the measured values are deemed unsuitable. The real-time local AOA and AOS of the FCS are calculated based on the obtained aircraft parameters. The inclination of each of the FCS relative to the critical values is dynamically limited according to the calculated real-time local AOA and AOS of the FCS. The aircraft may be an unmanned aerial vehicle (UAV) and/or a V-tail aircraft. The stall susceptibility condition may include icy conditions.
    • 一种用于动态限制飞机中单块飞行控制面(FCS)倾斜度的方法。 如果在当前飞行器环境中检测到失速敏感性条件,则激活FCS的动态限制。 获得飞机的实时校准空速,飞机的实时迎角(AOA)和飞机的实时侧滑角(AOS)。 如果测量值被认为不合适,则可以通过估计获得飞行器参数。 基于获得的飞机参数计算FCS的实时本地AOA和AOS。 FCS中的每一个相对于临界值的倾斜度根据计算出的FCS的实时局部AOA和AOS而动态地受到限制。 飞机可能是无人机(UAV)和/或V型尾翼飞机。 失速敏感性条件可能包括冰冷条件。
