As a GA pilot (although not flown for many years), required by the FAA or not, I would feel much safer flying knowing I have a back up paper chart. Not all rules and regulations by the FAA are 100% fail proof. Never flew with iPad or GPS but can definitely get around using pilotage and old school navigational aides like VOR, ADF, and ILS in IFR conditions.
Fair enough. You don't trust this new-fangled digital stuff. Welcome to the future.
