Many 'newbys' that only fly within Europe are unlikely to appreciate DME arcs, and the very many destinations in (for example, Africa) which don't have radar
Plenty of DME arcs in France. Perpignan and Ajaccio spring to mind. Ajaccio is a nice one - IAF on an NDB, then a nice long DME Arc, interception on a VOR QDM, then another intercept on the ILS, with another NDB as FAF. Loads to do for the pilot identing all the navaids involved - did my IRME test there!
