Patent number: 9026280Abstract: Provided herein is a method for detecting landing quality of an aircraft. Method steps include using an aircraft data system to determine whether a vertical speed rate is greater than a first preset value when the aircraft lands; determine whether a vertical acceleration is greater than a second preset value if the vertical speed rate is not greater than the first preset value when the aircraft lands; collect landing data; generate a landing message based on the collected landing data; store or transmit the landing message; and determine the landing quality based on the landing data in the landing message.Type: GrantFiled: July 26, 2012Date of Patent: May 5, 2015Assignee: Air China LimitedInventors: Huifeng Ding, Jiaju Wu, Yubin Wu, Yi Zhu, Minjie Tang, Zhiping Huang, Lei Chen, Jiang Yuan
