B737 unknown thing over MCP
Hey guys, I wonder what does it do, that cube*shaped solid over MCP - attached here as a photo?
Does anyone know what is it for? https://www.dropbox.com/s/rquu3rt3988uq28/cube.jpg?dl=0 Thanks in advance. |
B737 unknown thing over MCP
That monitors atmospheric conditions for suitability to activate chemtrail dispensing.
|
Am I correct in thinking its a reference point for pilots to adjust/align their seats?
FAR 25.773 (d) mandates installation of a 'fixed marker or other guide' in transport category aircraft to ensure that the pilots adjust their seating position such that they are positioned at the design eye reference point. |
I thought it was an ambient light sensor for flightdeck lighting.
|
Right, it is remote light sensor for CDS.
|
Be a bit daft having it in glaring sunlight with the rest of the flight deck in shadow.
|
Guess Boeing was a bit daft then placing it there. Have to say though, display light level adjustment works a lot better on the 737 than on the bus.
|
So guys still not satisfied with the answer. What I've been told is that that's for a lightning strike, to get the static load to protect MCP.
Asked the guy for the reference but couldn't show me, that's why I wanted to ask yo,u folks. So if anyone can explain with the reference instead of opinions, I'd appreciate. |

Manicured garden - ask your engineers...
Or find a reference in maintenance manual regarding glare shield construction to be able to "see" in manuals below the screwed on (top) cover. |
Guess Boeing was a bit daft then placing it there. Have to say though, display light level adjustment works a lot better on the 737 than on the bus. I have seen cases where the light sensors on the glareshield have been mounted backwards (maintenance error) causing the displays to go dim, even unreadable.

I think it is primarily to be used an attachment for the FO to secure his GoPro3 prior to any Facebook video upload.
Although I may be wrong. |
NSEU - Thanks for your serious answer & help.
Thanks a lot. |
Manicured garden, some references for your uninformed friend.

It has the dual function of light sensor and somewhere to rest the end of a clipboard. Or GoPro...
|
It serves the dual purpose of preventing you putting your clipboard properly on the glare shield and in providing a nice shiny surface to ensure an annoying reflection is cunningly placed on the windshield exactly in your line of sight.
Probably made by the same people who designed the seat adjustment mechanism to ensure the right position is not quite achievable :} |
The idea of placing a sensor in this position is to monitor the light level entering the cockpit window and control instrument illumination to track this level. So your eyes don't have to adjust too much when shifting your gaze from outside to the screens. Sensors on instruments work in conjunction with this to keep ambient light inside the cockpit from overpowering the displays.

Hello all and I have a question for Airbuses pilots:
Does Airbus have a similar system, please? Thank you so much! |
No, Airbus has a retractable table to do the job this sensor mostly does...
