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.
