Or using W instead of E?. We've all been there
When I got my first GPS, an 'end of line' hiker's (not pilot's) model much discounted at the HM stand at a Rally
, I had to insert all my own WPs manually from printed material (airfield guides, AIP, RAF AIDU En Route Supplements, aeronautical topo charts, even OS maps, ..) by hand. I then always did a 'sense check' for the generated tracks and distances on the route values displayed, by comparing them with the wax crayon line drawn on my own chart ..
It was thus that I found that a particular RAF (then active) airfield near but not on the 0 Meridian had E instead of W (or possibly the other way round) printed in the ERS, and it had been so for all the older Editions which I could find. I did tell AIDU (no one else had, apparently
), and it was corrected in future Editions.
