每一个优秀的人,都有一段沉默的时光。那一段时光,是付出了很多努力,忍受了很多的孤独和寂寞,不抱怨不诉苦,只有自己知道。而当日后说起时,连自己都能被感动的日子。 《尼克·胡哲给自己的信》
在去年年底,遇到了一起LEAP-1A发动机自动打印07报,代码:4210。研究了一段时间,当时很纠结,要不要下工作。和EMC的同学聊了一下,也咨询了厂家。考虑到滑油压力传感器的可靠性不高,如果发动机其它参数正常,在没有频繁自动打印,也没有LO PR警告的情况下,可以先预防性更换滑油压力传感器观察。但本着尽量避免过度维护的理念,我也一直没写相关的提示。
刚好空客最近发布了一个ISI 31.36.00122,声明了对于安装件号为ED48A200WR的FDIMU(SAFRAN),DMU软件件号为360-04422-055;或者件号为2234320-02-02的FDIMU(TELEDYNE),DMU软件件号为D12SAFC01C00000 or D12SAFC02C00000的飞机,这类警告为假警告,可通过升级DMU软件来解决。
AMM31-37-73中N2L2.1和OIPL1.1的对应关系如下:
但是ISI31.36.00122中给出N2L2.1和OIPL1.1的对应关系与AMM略有不同:
- Teledyne FDIMU Software PN D16SAFC03C00000 (SB 31-522)
- Safran FDIMU Software PN 263321489-( SB 31-1526)
This can be done by performing the two operations below:
Disabling the printing in the cockpit for the report 007 (all trigger codes).
This can be done through AIDS configuration through MCDU (refer to SubTask 31-36-00-740-085-A for going into output rules configuration menu):
MCDU menu AIDS/Airline Functions/Report prog./Report Routing/AIRBUS REPORT 7/ROUTE ALL REPORTS TO PRINTER END OF FLIGHT (page 11/12)/PHASE 9 - STATUS: set to NO (as already set today)
MCDU menu AIDS/Airline Functions/Report prog./Report Routing/AIRBUS REPORT 7/ROUTE ALL REPORTS TO PRINTER END OF FLIGHT (page 11/12)/PHASE 10 - STATUS: set to NO
Activating the immediate print of all trigger codes of report 7, except code 4210.
For all trigger codes except code 4210 (page 5/12) set YES for option “TO PRINTER AUTOMATICALLY”:
MCDU menu AIDS/Airline Functions/Report prog./Report Routing/AIRBUS REPORT 7: On pages 2, 4, 6, 7, 8 and 9/12 , “TO PRINTER AUTOMATICALLY”: set to YES.
Nota: In this case, if an event trigs a report, it will be generated immediately at generation time (when the event occurs), instead of being printed at end of flight (as per default behaviour).
B- It is possible to inhibit the ACARS sending of a given trigger code.
This can be done through the same page as above:
For example, for code 4210, in page 5/12, it is possible to inhibit the transmission of the generated report 07 code 4210 through ACARS by setting STATUS:NO at 'TO ACARS AUTOMATICALLY' option.
(With this option, the report is still generated and stored but not sent through ACARS).
