I recently got to sit in the cockpit of a new (less than a year old) United 737-900 and what surprised me and scared me was it was all glass...even the backup gauges were glass...what ever happened to the backup steam gauges ...what if there is a total electrical failure in imc conditions? I understand the pilots may have tablets with gps and moving maps but why get rid of the one thing that won't let you down at the end of the day?

Fly-by-wire is great, until the wire breaks. You post reminded me of the 'Children of the Magenta" presentation from 1997.

There was a cirrus in 2007 flying CYPQ-KBUF that had electrical failure of his PFD over Lake Ontario at night...tower had to talk him down to the airport. Pilot was drenched in sweat when he finally got out...

Sam, that raises some valid considerations in my opinion.

Sam, what's potentially scarier is if those screens are powered by something like "Windows"... and then the proverbial "blue screen of death" might take on an entirely different meaning.

Hoping for some redundancy there in the cockpit... especially if I'm on that airplane!

Ditto for the VOR navaids as redundancy to satellite based nav systems.

The check pilot at the airshow claimed the backups were powered by a secondary power source...does me mean a separate battery?

An excellent question, Sam. Hope it's a "Die-Hard" battery!
