Jesus ! Which year are you stuck in ? ? Procedural ATC is no longer available in European continental airspace, since decades. no tools for that anymore ( strip boards) nobody is trained anymore to do it either. . It is all 100% digital , if the screens go blank, you have zero info.
Simple analogy : if you read a book on your tablet or Kindle and it breaks down , you cannot continue to read unless you have bought the paper book as a back up .
Well most if not all ANSPs have decided buying paper books for back ups were too expensive and teaching people to read on paper would be a waste of time and money.
So here you go. Welcome to the 21st century..
