No, I wouldn't think breaking the glass of the CRT's would work, either, :-)
and that's not what I intended to convey. I was referring to the stand-by
instruments, and the possibility that they are still hooked up in a
'traditional', direct fashion. I don't believe that this would be an option in
the newest generation (777, et al) but may have still have been an option on
the 757/767 with its combination of 'steam' gages and CRT's. Or are you saying
that even the stand-by gages are driven by air-data computers?
