Right,
I have read all seven pages and these last few of slinging pies can be covered by PM's don't you think?
In summary there are some issues I would like to highlight:-
1. Asking for re-teaching (or initial teaching) of the PPL getting lost procedure is probably in order for the original poster. HOWEVER, We're all assuming that this original poster did not get taught this, his question could have been "on top of the usual stuff what else can I do?"(Like the calls for rules of thumb which there are heaps on these forums). There have been many good answers to this question.
2. We have had people from D&D say, "Call us we will help!" yet we have posters saying, "don't call unless really needed." I think this becomes a personal preference, although I don't fly in the UK I would be inclined to call. Better to ask for help early than say a very big sorry to a very big aeroplane and filling in lots of forms! It comes down to airmanship really, "situational awareness"..Helloooo!
3. There is nothing wrong with using a GPS. Totally relying on said GPS to me is an issue, so back it up with your other skills - DR and other Nav equipment. I actually try and use DR (with a GPS backup) GPS covered or turned off means I can have fun looking outside and seeing things. After all I am paying a fair amount for the view. No I don't fly IFR.
4. I have been "geographically embarrassed" before, several times. I have used all available to me, even other aircraft in range. A bit of an experience but I bought a few guys a few beers in the bar that night. Personally I would love to be able to help out if someone else was in that position.
And that all I have to say about that.
