Not sure if BEagles comment about glib planning refers to anything I said in my post..... anyway, if we are talking about Nav planning I think you also need to consider the context. For example, if I was on a PPL or CPL training course, overseas landaway etc... I would plan with whizz wheel and do a full PLOG etc... If I was just doing a localish landaway, say Leicester to Sheffield City I would draw on the route, work out wind corrected headings, ground speeds, times at fixes etc.. with MDR and back that up with a GPS route to same points. Flying it I would use my fix times backed up with the 'time to' type function on my GPS as a cross check. I don't think that's gash?
