So what's "limited panel" under glass, and what would do you do when you discover your plane's comfortably warm interior isn't as waterproof as you thought when it suddenly goes dark?
Lim panel was based on the failure of vaccum driven instruments, IE: AH & DG. That was hard work! Lim panel obviously isn't the issue on glass just a total display failure in which case there would be a seperate back up glass panel, albeit smaller and more basic. At the Airline level it's more about switching from one source to another in order to get enuf displays to get you home, so to speak -)
