White Oval Device On A 737?
Hello All:
Was working A/C 496WN the other night, and I came across the white oval device as seen in the picture below. I've noticed many of our 737s ( both -300 and -700's ) have this and was always curious about the overall purpose of it.

Boeing forgot to remove the anti-theft security sensor before delivery.
Slower traffic, keep right

BEEP!
I´m no expert, but here goes, is it a static port or something....

I just went thru 600 some 737 nose pictures trying to better define the white ovals, didn't come up with much.
However it does seem to be fairly recent. And it's located about where the airstair controls are on aircraft so equipped.
I'll suggest it's part of the upgrade mentioned in this thread:

I can't recall the specifics, but it's an atmospheric sensor that reads and sends back real-time information to (I think) NOAA. I'm heading to wok today, so I'll see if I can't get more details.
Btw, the upgrade to the classic's mentioned in ZAN's link is DOA.

Excellent... When in doubt ask the man who flies one...

I gave it a shot...
Water vapor sensor. Looks like a joint Southwest/ARINC/NOAA project...

Wow, Barney Captain, someone pays attention. You are right and so is ZAN. I think we only have 4 aircraft that have these installed. I can't recall the exact date these were done but it has been 3 or 4 years on the classic.

Anyone having more Info on this sensor......
I may not win often, but I damn well never lose!!!

"Excuse me, sir, is that a 737 in your pants or do you just really like shopping here?"

Did you see ZAN's link? It was pretty comprehensive.

A friend who works in SWA engineering told me that they have the sensor installed on about 60 aircraft (about half on-300's, half -700s). They are looking to install them on -800s but they haven't done any of them yet.
The program is a partnership with the National Weather Service. Rumor is the NWS is absolutely thrilled with the data they get from the airplanes. They also have other airlines participating in the experiment but he doesn't know who.

From the Spectra Sensor website:
4.0 State of the WVSS-II Network in the U.S.
As of June 2012, there are 56 WVSS-II equipped aircraft in the U.S. network, including 25 units installed on UPS 757-200 aircraft, and 31 units installed on Southwest Airlines (SWA) 737-300 aircraft. An additional 36 units are scheduled for installation in 2012 on SWA 737700 aircraft. Figure 3 illustrates the data collected from the aircraft that were in operation within the U.S. during a 24 hour period, June 13, 2012. While there are still many areas in space and time that have yet to be covered, this demonstrates the growing spatial and temporal coverage that is obtained through aircraft observations with WVSS-II.
There are 12 WVSS-II units currently delivered to various organizations in Europe for use in operational and research applications. Short term plans are in place for further expansion in Europe. The Australian Bureau of Meteorology has also begun to expand their AMDAR network, starting with 3 WVSS-II units in 2012. Planning is underway for implementations at various other National Meteorological and Hydrological Services around the world.
While researching this topic earlier I'm quite sure I saw that LH was the European participant in the program.
