The invention relates to a method for testing an aircraft landing gear. The landing gear comprises a first wheel and a second wheel; a first brake system and a second brake system; a first tachometer output line and a second tachometer output line; a first brake command line associated with the first tachometer output line; and a second brake command line associated with the second tachometer output line. The method includes generating a test signal with a first tachometer, wherein the first wheel does not rotate during the generation of the test signal; receiving a test signal via one of the tachometer output lines; issuing a brake command in response to receipt of the test signal, where the brake command is issued via a brake command line associated with the one of the tachometer output lines; and monitoring a response of the first braking system or the second braking system to the braking command to test a cross connection between the first braking system and the second braking system.
本发明涉及一种测试飞行器起落架的方法。起落架包括第一轮子和第二轮子;第一制动系统和第二制动系统;第一转速计输出线路和第二转速计输出线路;与第一转速计输出线路相关联的第一制动命令线路;与第二转速计输出线路相关联的第二制动命令线路。该方法包括:利用第一转速计产生测试信号,其中,第一轮子在测试信号产生期间不旋转;经由转速计输出线路中的一个转速计输出线路接收测试信号;响应于对测试信号的接收而发出制动命令,其中,制动命令经由与转速计输出线路中的所述一个转速计输出线路相关联的制动命令线路而发出;以及监测第一制动系统或第二制动系统对制动命令的响应,以对第一制动系统与第二制动系统之间的交叉连接进行测试。
