The problem is we don't train new pilots on how to correctly use the new technology, its just banned from the cockpit and then the new PPL figures it out for themselves. What is needed is an introduction to based navigation principals and then how they can be used to provide a sanity check to the electronic magic and how to gracefully recover when the screen suddenly goes blank.
It is important to realize that the traditional methods of navigation were used because in the old days there was no way to have updated positions and rate of change of positions in real time. GPS obviates this challenge and provides much increased precision and accuracy for pilot navigation. It is IMO stupid to deliberately use a less accurate method of navigation. But and this is a big but, it is also easy to to miss use it so understanding what it is telling you is a skill that can and should be taught. to new pilots.
