Potkettleback -
LORAN is alive and well and indeed is just evolving into eLORAN which is about the only viable backup to GPS, since its signals are relatively unjammable (you can easily jam GPS signals with kit from Radio Shack). It now comes on a slot-in card for the GPS in your aircraft.
With reference to common sense and questions - one of the new subjects on the Helicopter ATPL is Image Intensification. They are perfectly aware that the average new pilot won't get to see such technology until they get several hundred hours under their belt, and I gather that the tactic will be to leave such stuff in the syllabus so that you know about it, but just not ask questions. Let's hope it works!
