If the RAF still navigates this way, it is as well it is the Americans who get to do the dirty (but usually necessary) work around the world today!
Recently I spoke to a Hawk pilot (an instructor as it happens, too). He said they navigate absolutely using dead reckoning, map, stopwatch. GPS is out of the question. I asked him what would be the function of a Hawk in a real conflict. A long pause followed........ the enemy would only need to wait for some clouds to form

All the above are within the thickness of a line on the printed chart.
Perhaps someone with more time will look up the official lat/long in the AIP but frankly I doubt ALL the above products are wrong! I also know the last one above was no more "wrong" than the printed CAA chart itself because one can overlay the chart grid onto the map display and see if the two grids line up.
So I wonder just what "database" the King Air was using.
How many more GPS navigation products do you want me to dig out? I have an old Skymap 2. I also have a KLN94 and KMD550. But these all use the Jepp vector database.
There was a stand-up comic on TV who used to always start with "I am going to tell you a story...." (Frankie Howerd)? I can tell you a story about a VOR receiver which would show a perfectly plausible radial, no flags showing, but it was complete rubbish. I also used to fly an Archer whose DME would show anything it felt like, but most of the time it mattered (say on an NDB/DME approach) it was usually plausible, but it was rubbish. Now, that is really dangerous because all multi-step step-down approaches are that way for terrain clearance. So, let's ban VOR and DME navigation.
As a general comment, I doubt whether more than 1% of UK PPLs read this stuff. However, the pro-GPS and anti-GPS pro-modern anti-modern conflict pervades GA very thoroughly everywhere (except among pilots who go places and who can't be bothered to argue about nonsense like this). It does not suprise me, given the wide range of types of aircraft operated, and the huge range of pilot ages. What does suprise me is the way the GA Dept of the CAA remains on the sidelines, letting it carry on. All the while approving BRNAV units, which makes a mockery of the attitudes of its (very small) GA Dept.
