The CAA are always banging on about not using GPS.
I think a CAA sponsored "Correct use of GPS" would be a good start. Many people still enter numerical co-ordinates, don't check against the map, regard it as their nav tool, not 'one of their nav tools', etc.
If the CAA put a show together, perhaps with industry help, they may also realise that GPS is not the demon its made out to be and, when used correctly, is a huge aid to aviation safety.
