Well when I read the transcript of AF447, it sounded like they lost situational awareness...maybe the computers were rebooting after a lighting strike...or the tubes all went red...either way....not having anything else as a reference, just tv screens, all relying on one computer, make you ponder having one mechanical peanut gyro and and ILS head. It's old school, but it's also peace of mind.
I carry a handheld GPS as a back up, surprisingly accurate, barely doable for an approach but better then trying to do it at night in a dark aircraft with no electrical.
