The exported files from SD claim to be compliant with Topografix GPX 1.1, but validating the GPX against the scheme definition fails. Apparently, the element <speed> is not part of the <trkpt> element, as defined in the GPX standard scheme. I strip of the <speed> element using GPSBabel, so I have a work-around which works fine for me. GPSBabel is freeware, importing the SD GPX files as "GPX XML" and exporting them as "GPX XML" again is all that is required. Nevertheless, is there a way I could export my flight log as a formally correct GPX file? Hartmut

In GPX 1.1 there does not seem to be a <speed> element. This seems to be the valid link for the current GPX standard: https://www.topografix.com/gpx.asp
