quote from Peter2000 (who has some very interesting articles on IFR flying on his website by the way, well worth a read)
"Another is the need to embrace modern navigation. Navigating with the map, stopwatch, and compass is a tedious and highly error prone procedure which remains popular with a hard core of "traditional" pilots and these will find it harder to get used to something a bit faster. I had no problem with this since I discarded all PPL navigation training the day after the PPL skills test, and used GPS backed up with conventional radio navigation (VOR/NDB/DME) as the sole means of going everywhere. The benefit of this is that the workload of flying is a tiny fraction of what it is during training"
