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.
Automatic lighting control on the 737NG and other Boeing types involves both the glareshield sensors
and the ones on the display units.
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.
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.
Did this coincide with April 1st?
