A method of monitoring the condition of a shock absorber (9) of an aircraft landing gear (1), the shock absorber comprising at least one spring chamber (18) containing a gas (22), the method comprising making a plurality of measurements (40) of the gas pressure and temperature, each pair of gas pressure and temperature measurements being made at the same time associated with the shock absorber duty cycle; calculating (42) a first value based on each pair of gas pressure and temperature measurements; storing (44) the first value in a log; determining (46) a value trend based on the log; and generating (50) a first notification signal in response to determining (48) that the value trend is outside the first range of values.

    一种监测飞行器起落架(1)减震器(9)的状况的方法,该减震器包括包含气体(22)的至少一个弹簧室(18),该方法包括对气体压力和温度进行多个测量(40),每个气体压力和温度测量对是在与减震器工作循环相关的同一时刻进行的;基于每对气体压力和温度测量来计算(42)第一值;将第一值存储(44)在日志中;基于该日志来确定(46)值趋势;以及响应于确定(48)值趋势在值的第一范围外而生成(50)第一通知信号。
