工卡上写的有733的是3个跳开关。738的是4个跳开关在正驾驶后面的面板上。叫lavatory什么的几个跳开关

刚刚查了下737-300的压力放饮用水程序是拔P8板上WATER HEATER跳开关。重力放饮用水系统是拔P18板上的盥洗间水加热器跳开关。737-800的是拔
LAVATORY WATER HEATER A
LAVATORY WATER HEATER D
LAVATORY WATER HEATER E
LAVATORY WATER HEATER G这四个跳开关。至少我们这里是这样的

我们都从来没拔过，直接放

什么是跳开关呀...新手勿鄙视

应该是拔厕所里洗手池的加热壶的跳开关，因为没水的话通电加温会烧坏加热壶

心泪无痕 · 发表于 2010-1-7 12:41:35

737-700的话要拔，737-800的不要拔。具体是哪个还真不清楚了。

一直是航后结束断电后放水，没拔过跳开关。看了这个帖很惭愧－－经验主义害死人，学无至尽。

jellyfish37 · 发表于 2010-8-3 20:08:29

还要拔跳开关啊？

lbb032401q · 发表于 2010-8-4 08:36:02

晕啊，原来还要拔跳开关

有点乱啊到底要还是不要啊

chaizhiwei123 · 发表于 2010-11-19 09:57:15

以前也没拔过，不过现在知道了还是要拔跳开关的~

zhuomu · 发表于 2010-12-30 17:09:54

你说的有一定的道理，但根据多年的维护波音系列飞机放水从来就不做这项工作。也没有出过任何事情，既然有人提出这个问题也是件好事，学习啦！谢谢！

一直没有拔过，个人觉得影响不大，还有就是直接关掉厕所加热的就好了吧
