Its amazing how technology has changed the game for navigating, with essentially free apps running on phones and inexpensive portable units that provide such an accurate backup source of situational awareness. I fly with a rock solid panel mounted VFR Garmin 496 and no matter how hard I try to fly with reference to the CDI only, a 2 second scan of the moving map puts it all in perspective. Old school flying? Probably not, but simple and efficient. Young pilots in the future will laugh at concepts such as slant range and zone of confusion.
