The lessons in VOR/DME/ADF changed the way I fly! Still like to be able to pinpoint on a map where I am, and stil PLOG properly etc. But RNAV is my prefered choice.
However proper DR is soo satisfying! flew from EGKA to Sandown the other day, only a short flight but got there sans rnav, gps etc within a minute of my "guess" - sorry estimate!
