Stan,

In my humble opinion,

1. Get a quality mechanical backup, put it somewhere on the panel where it is very visible.
2.  If your glass panel so much as blinks in IFR weather, fly the gyro, and DECLARE AN EMERGENCY!!!

Glass panels are great they make flying, particularly IFR, infinitely easier.  Unfortunately they have 2 bad sides.  1. They're computers.  2. By relying on them we quickly lose our old IFR skills. 

I doubt anyone really maintains enough IFR currency to be able to safely fly a faulty glass panel with the typical partial 6-pack installed as backup.

Hello Tom,
 
I was afraid someone would say that. Obviously looking at all the panels in our 
fleet, most have steam gauges as primary or backup. While I don't intend to 
joust with Thor, it may be unavoidable some day. It may not be possible to 
isolate all of the electronics from a lightning event but I'd hoped the state of 
the art had advanced enough to make that risk acceptably small. It would be 
interesting to know how many pilots flying dual EFIS panels with backup gauges 
were forced to rely on the gauges at some point. 
 
Building electronic redundancy gobbles up panel space but perhaps with a little 
shuffling I can fit in a 3 pack - even with a small Legacy panel. 
 
Stan
