[quote] As for tying up the resources of D&D because your kit has packed up and you can't be bothered to find yourself, well.... A wind up, perhaps? <hr></blockquote>
D&D is funded by the state. What the state wants is to retrieve military jets with engine failure, stop you and the missus ploughing in to a hill side fair enough, but that's not the end of it. A big cost to keeping the whole show running is a PA28 flyer struggling with his map around his neck meanwhile sailing through Heathrow, Gatwick, Manchester etc.
Assume GPS etc (and you would have two obviously!)fail very rarely. When they do, just ring up D&D and ask them whether they want you to keep off their wavelength or they would like you to stay until you are out of harm's (ie other people's) way. I'd wager they'd be only too pleased to help avoid an incident.
I'm not saying The New Method is mandatory. Just don't feel guilty if you don't want to do DR after your PPL/CPL, particularly in poor visibility.
