Thanks very much for the useful information. It's encouraging to here BEagle that the examiner wants you to pass
Noggin, thinking about it now, I did pinpoint Kinross ok on the map, and did the necessary calculations, but with the higher workload involved, I managed to miss the relevance of the big puddle! Amazing in hind sight.
I think I over corrected for the wind, and ended up travelling in a direction clearly heading right of the Loch.
I think the gross error correction is what I'm thinking about. As long as it's ok to say "Looking at the map, I should be heading towards a large water feature, which I'm not, so I'll make a track error correction of xdegrees", and continue looking for visual confirmation.
Must visit the flying club this weekend, and see about another lesson!
