Strikes me that it's often technology for technology's sake. We were told that when we moved to the new approach room at Heathrow when simple tasks like entering a 4 digit transponder code on the radar took about a dozen steps witj on screen menus, etc. The old clockwork system did it in seconds.
Don't know if Gonzo remembers the old 6th floor approach room? On the wall at the north end was a bank of telephone keyboards which were copies of all the other keyboards in the room. They were selector panels and when a position was opened or closed one simply selected or deselected the telephone lines one required using the "copy" of the keyboards on the operational postions. It never went wrong. Come back clockwork!
