关于DEU无法进入自检的说明
机队历史偶尔会出现DEU新件装机后发现无法进入自检的情况,通过对串DEU仍无法恢复,最终再次更换DEU后恢复正常。
针对DEU无法进入自检的情况,厂家发布了SIL对该问题做一说明,当出现CDS FAULT信息,同时无法进入自检时,通过复位DEU主用跳开关进行复位,若信息消失,则无需更换部件,以减少NFF的发生。目前FIM 31-62 TASK884已参考厂家SIL进行了更新。

针对CDS FAULT信息无法进入自检,或新件装机无法进入自检的情况,建议参考FIM和SIL进行检查后,若复位跳开关,重装或对串部件仍无效,则安排更换。
737数据记录的起始时间
1,FDR CONTROL LOGIC:
START: Recordings will only take place if either N2 is greater than 20 %RPM.(实测)
STOP: Stop recording will only take place if either N2 is less than 20 %RPM.
还有一个通用性说明如下:
The FDRS operates automatically when one of the engines is in operation((Engine running is when N2 > 50%)) or the airplane is in the air. lt also operates on the ground when you put theTEST/NORMAL switch on the flight recorder test module in the TESTposition.
2,QAR CONTROL LOGIC:
START: Recordings will only take place if either N2 is greater than 20 %RPM.
STOP: On the ground up to about 25 seconds after last engine shutdown.
3,WQAR 2G & 3G CONTROL LOGIC: BOEING
START: On the ground with one engine running (~ 20% of N2).
STOP: On the ground up to about 10 seconds after last engine shutdown.
4,WQAR 2G/3G LOGIC: Teledyne STC
START: On the ground with forward entry door is close.
STOP: On the ground up to about about 3 minutes after last engine shutdown.
