Pilot here(private pilot, anyway), and yes: we use the E6B a lot when we're up there. It's nice that avionics can give us things like true airspeed and fuel burn rate instantaneously, but that's only as good as your power source is when it's working correctly. An E6B will never suffer from electrical failure.
