Down that path, as I am working on my CFI I am wondering how basic pilotage and navigation is even taught or tested these days. Paper charts are all but gone the way of the dinosaur. I have used or seen a current one in years. I learned the old school way, paper chart, navlog, magnetic variation, all that, and its nice to be able to say I could do it if I could. But if a new pilot has no intention of ever having a paper chart at their disposal, is there much purpose in teaching it? I know my more recent checkrides I did it both ways, and the DPE just told me, show me how you would do it for real, not just for the test.
I am still leery of being electronic dependent, and insist on having redundency, at a minimum the panel mounted unit, plus a ship powered handheld unit with battery backup. Usually I have a third in the form of a Ipad for even more redundency. I did have a failure on a recent trip though that made me think more about those options. I had a quick ferry cross country I was called upon to do. Mid way realized I didn't have my Ipad, but thats ok I have two other means of navigating plus the Mk1 eyeball. Then the handheld crapped out and it occured to me I was down to just the panel mounted GPS, and wasn't terribly familar with the area I was flying in otherwise. Through good fortune and clean living...ok plain luck and praying like hell... I survived, but it made me think.
