求教关于FMC软件问题

liujinglun · 发表于 2009-10-22 19:25:05

请问FMC软件U10.2版本和U10.6版本各有什么缺陷？我们的飞机737700近距离转场着陆时有时会两个CDU黑屏，之后FMC重启，航线数据全部丢失和软件缺陷有没有关系呢？谢谢了。

这不是机务的活，问工程技术部门

看来得问波音工程师了

根据737NG-FTD-34-09007波音将发布FMC 10.8A版本软件解决此问题。

这应该是10.7前各版OPS的一个缺陷，波音曾经的说明：The restart was due to a known condition in the Update 10.7 FMC software where the FMC restarts repeatedly upon entry of cruise altitude on the cruise and/or perf init pages. The restart is due to an unhandled software exception in the FMC computation of crossover altitude, where the possibility of a division by zero existed. This problem was addressed in Update 10.8 as noted in Boeing Service Letter 737-SL-34-193-A. As GUN is aware, the U10.8 FMC software has been removed from service. This condition will also be addressed in the U10.8A FMC software scheduled for certification in April/May of this year.
