A320飞机的机翼过热探测环路经常出现故障信息,其中常见的是在航后报告多次出现“R WING LOOP A”的CFDS故障信息,根据此信息排故手册TSM有明确的排故程序。但如果故障发生在只有一个环路探测到故障信息且外界温度较高时,在对BMC计算机进行测试时往往会出现TEST OK的情况,虽然排故程序中说明不需要做任何工作,但这种情况并不表示没有故障存在,它有可能是因为过热探测元件的芯和外包皮之间的绝缘层阻值 A320 aircraft wing overheating detection loop often failure information, which is common in the air after the report appeared several times “R WING LOOP A” CFDS fault information, based on this information troubleshooting manual TSM clear troubleshooting program. However, if the fault occurs when there is only one loop to detect the fault message and the outside temperature is high, TEST OK often occurs when testing the BMC computer. Although no work needs to be done in the troubleshooting procedure, The fact does not mean that there is no fault present, it may be due to the insulation resistance between the core and the overcladding of the overheating detection element
