Question about the C3 panel - CRTs Power ON/OFF ?

[Cthulhus]

Hello,

I have one question about the CRT1 ON/OFF, CRT2 ON/OFF and CRT3 ON/OFF that you can found on the C3 Panel. On the "old" cockpit shuttle, those switch was used to turn off/on the 3 CRTs screens. I remember reading somewhere that we had to wait up to 60 seconds for the three CRTs turn on.

Now with the Glass Cockpit Next Gen, the 3 CRTs have been changed to 3 flat MDUs screens. And on each MDU, you have on the bottom left a ON/OFF switches.

Now my question, what is the difference between the 3 CRTs ON/OFF located on the C3 panel and the each ON/OFF switch located on each MDUs/MEDS screens ?

For me, it's the same, so why the 3 ON/OFF buttons still on the C3 panel ?

I see nothing about this on the SCOM manual.

Any ideas ?

Thanks

AFAIK, the ones on the MEDS operate on the MEDS electronics, the ones on the C3 work on the BUS - they essentially have the same effect, but do it a bit differently.

That's correct when you do a group A,B,C, powerdown, you always power down the CRT's using C3.

The CRT power switches are located on panel C2 by the way. It's labeled incorrectly in SSM.

Yes, correct ... It's C2

I thought we fixed that in one of the features sets...
