What's this 737 thing?

Sun Aug 28, 2016 2:58 am

Couple things on the 737 I'm curious about....

1) What's this plastic thing in the top of the window? It looks like it's stuck to the inner window pane.

2) Is there a battery in my overhead baggage compartment?

3) On the left side of this 737-300 E&E bay is what looks like an electric motor attached to a jackscrew. Is this the airstair door opener?

2) Guessing those are batteries for the oxygen mask deployment mechanism.

1. Air dampener. It covers the vent hole in the middle pane and is there to prevent fogging of the window.

2. marker to indicate the location of emergency lighting batteries. They aren't located overhead, they are behind the sidewall by your feet.

3. Yes.

Everything Yeelep said is accurate.

Starlion, there aren't separate batteries for the oxy mask solenoids. The release system is powered by the 28VDC battery bus.

And those stickers are REAL handy when you're trying to find the exit light battery pack in a hurry. Or at all.

Regarding 3), note that there are two motors... one is AC, the other is DC. DC takes about a week and a half to open the door and get the stairs out!
