Some seem to prefer getting from A to B whilst practicing bleeding.
However, I've been flying for a living for almost forty years. Much of my earlier life involved single pilot DR nav at low level, at a variety of speeds, up to 330 kts in military aircraft, with an accuracy of arrival time of +/-15 seconds. I used to teach same to others.
But I'm now fully converted to GPS. No doubt my DR skills are much eroded, I know I could pick it up again fairly quickly if required. I do carry a DR nav planning kit but can't recall the last time I used it; it was possibly fifteen years or so ago.
However, I fully recognise that could not do the job I do today as safely, accurately or efficiently without GPS and I have no intention of trying to perhaps satisfy some strange macho ideal of others by attempting to do so.
