摘要：
A method for determining a hard-landing occurrence for an aircraft has sensors at selected positions of the aircraft. A model defining critical points throughout the aircraft is obtained. Data is received from the sensors when the aircraft lands. Diagnosis values for all critical points of the aircraft are calculated by applying the model to the data from the sensors. The diagnosis values are compared to threshold values for the critical points of the aircraft. A hard-landing occurrence is determined from the comparison between the diagnosis value and the threshold value. A hard-landing occurrence determination system for an aircraft is also provided. Sensors at selected positions of the aircraft provide data related to accelerations at landing of the aircraft. A diagnosis processor unit determines the hard-landing occurrence, and comprises a model database, a threshold database and a threshold comparator. A hard-landing occurrence interface signals a hard-landing occurrence.
摘要（中）：
用于确定飞机的硬着陆发生的方法在飞机的选定位置具有传感器。 获得了定义整个飞机上的关键点的模型。 当飞机着陆时，从传感器接收数据。 通过将模型应用于传感器的数据来计算飞机所有关键点的诊断值。 将诊断值与飞机关键点的阈值进行比较。 根据诊断值和阈值之间的比较确定硬着陆事件。 还提供了用于飞机的硬着陆发生确定系统。 飞机选定位置的传感器提供与飞机着陆时的加速度有关的数据。 诊断处理器单元确定硬着陆发生，并且包括模型数据库，阈值数据库和阈值比较器。 硬着陆发生界面发出硬着陆事件。
