Plans
All my journeys by air seek the Air_geohash_achievement. The 10 arc second rule means you need to be under 310 metres from the hashpoint. My napkin aproximath suggests there as a 0.1% chance of meeting this goal crossing one graticule. On a mid length flight you might cross 50 graticules so now there's a 5% chance of success. Frequent flyers will certainly succeed eventually.
Expedition
I had programmed the decimal parts of the coordinates into my Garmin eTrex 20. Every 10 to 15 minutes I re-programmed the graticule coordinates and watched the distances fall and rise again. In 43,19 the distance was dropping rapidly and after each screen update I was grabbing the image. The best screen shot was at 123 metres from the hashpoint, well within the requirements.
A bit of post-processing in Google Earth confirmed the result.
The eTrex 20 lacks a barometric altimeter so you get true altitude in an aircraft and not the cabin pressure altitude.
