Mind you, there's GPS & then there's applying the "Mark 1 Eyeball" to it.
I was using GPS to find the aerodrome at Ancenis once. I'd been there before but couldn't, on that previous occasion, find the field. It should have been easy as it's just north of the River Loire straight on from the bridge, & I knew that I was flying pretty much vertically above it. But, I couldn't see it.
On the 2nd. occasion, using the GPS, I felt I was sure to spot it, & this time there were two of us. The GPS indications were obvious but, could we see the field ? No, we couldn't, despite the fact that I knew that I was right above it - again. And, it was CAVOK !.
I swallowed my pride & went on to the next field - no difficulty there, thank goodness.
