    • The present invention concerns a method for starting a test testing the operation of at least one fan designed to cool at least one computer of an aircraft turbojet engine, said method comprising steps of: - comparing (E1) the number of flights carried out by said aircraft since the last operation of the fan (N) with a first threshold (y), - comparing (E3) the number of flights carried out by said aircraft since the last operation of the fan (N) with a second threshold (x), said second threshold being greater than or equal to the first threshold, - acquiring an environmental parameter (T) and checking if the parameter satisfies a limit environmental condition of operation of the fan (E6), - controlling (E8) the starting of said fan operation test when the number of flights carried out by said aircraft since the last operation of the fan (N) is greater than or equal to said first threshold (y), less than said second threshold (x) and when the acquired parameter (T) satisfies said limit environmental condition.
    • 本发明涉及一种用于开始对设计的至少一个风扇的操作进行测试测试的方法,所述方法包括以下步骤: - 比较(E1)从风扇(N)的最后操作开始由所述飞机执行的飞行数, 具有第一阈值(y), - 比较(E3)所述飞机自从风扇(N)的最后操作以第二阈值(x)执行的航班数,所述第二阈值大于或等于 第一阈值, - 获取环境参数(T)并检查该参数是否满足风扇操作的极限环境条件(E6), - 控制(E8)开始执行所述风扇操作测试时的航班次数 所述飞机自从风扇(N)的最后操作大于或等于所述第一阈值(y),小于所述第二阈值(x)以及所获取的参数(T)满足所述极限环境条件时。
