Air Geohash

The following ribbon is available for achievers of the Air Geohash. Follow the instructions to customize it for your geohash.

This user earned the Air geohash achievement

by reaching the ({{{latitude}}}, {{{longitude}}}) geohash on [[{{{date}}} {{{latitude}}} {{{longitude}}}|{{{date}}}]] by air.

“	"How are you flying?" "I learned Python! [...] I also sampled everything in my medicine cabinet, but I think it's the Python."	”
—XKCD

The "Air Geohash" achievement can be claimed when a Geohasher reaches the correct location for that day (and supplies proof -- a picture of you in an airplane isn't enough) while in an airborne vehicle. Jumping in the air does not count.

Commercial passenger flights

It is theoretically possible, although very unlikely, to pass through a geohash while a passenger on a commercial flight.

Please note, there is widespread disagreement about the validity of the "10 arc second rule". Please see the Talk page for details.

- If you believe in the "10 arc second rule" (heavily contested), you need to get within approximately a few hundred metres. (This was once calculated at 310m but varies depending on altitude and latitude).
- Napkin aproximath suggests there's a 0.5% chance of meeting this goal crossing one graticule. On a mid length flight you might cross 50 graticules. That gives up to 25% chance of success. Frequent flyers will certainly succeed rather easily.
- Don't try to persuade the crew to alter course in your favour - that would be hijacking!
- Try to contain your squeeks of excitement as the distance falls followed by the satisfied "Yes" if it drops below 310 metres. Geohashing is hard enough to explain as it is! --Sourcerer (talk) 11:51, 5 February 2018 (UTC)

Acceptable proof

In addition to the standard proof listed on the Achievements page, for aircraft in flight, a photograph which shows all of the following will also be acceptable:

Your stupidly grinning face.
Something displaying the date (typically your GPS)
A Geosync device showing you to be within
10-arc-seconds or 0.00278 degrees or 310 metres E/W and within
10-arc-seconds or 0.00278 degrees or 310 metres N/S of the correct location. (Please note there is widespread disagreement about the validity of this definition of success. Please see the Talk page for details.

-== Air Geohash Subcategories ==
+=== Commercial passenger flights ===
-Add the applicable subcategory to your award ribbon. If you achieve the Air Geohash more than once in different subcategories you may list them all on the same ribbon or take separate ribbons as you wish.
+It is theoretically possible, although very unlikely, to pass through a geohash while a passenger on a commercial flight.
-* For geohashers who are the actual pilot-in-command at the time, use '''Pilot'''
+Please note, there is widespread disagreement about the validity of the "10 arc second rule". Please see the [[Talk:Air geohash achievement|Talk page]] for details.
-** For an Air Geohash: Pilot award that is achieved ''while in actual IMC conditions'' (no hoods or foggles!) the '''Master Pilot''' award is available.
+**If you believe in the "10 arc second rule" (heavily contested), you need to get within approximately a few hundred metres. (This was once calculated at 310m but varies depending on altitude and latitude).
-** For an Air Geohash:Pilot award that is achieved ''while piloting a helicopter, Harrier jet or similar hovering craft'' '''Hover Pilot''' award is available.
+**Napkin aproximath suggests there's a 0.5% chance of meeting this goal crossing one graticule. On a mid length flight you might cross 50 graticules. That gives up to 25% chance of success. Frequent flyers will certainly succeed rather easily.
-** For an Air Geohash:Pilot award that is achieved ''while piloting a dirigible'' the '''Blimp Pilot''' award is available.
+**Don't try to persuade the crew to alter course in your favour - that would be hijacking!
-** Flying a kite equipped with a GPS now qualifies the Geohasher for a [[Geohash By Proxy]] achievement.
+**Try to contain your squeeks of excitement as the distance falls followed by the satisfied "Yes" if it drops below 310 metres. Geohashing is hard enough to explain as it is! --[[User:Sourcerer|Sourcerer]] ([[User talk:Sourcerer|talk]]) 11:51, 5 February 2018 (UTC)
-* For geohashers that are at or above 5280' (1609.34m) AGL at the time of photographic proof, the '''Mile High''' award is available.  (May also be achieved skydiving, of course!)
-* For geohashers in a hot air balloon at the time of photographic proof, the '''Balloon''' award is available.
-** ''NOTE:'' Air Geohash:Balloon is NOT available for floating a balloon on a string over the spot.  You might be able to pass that off as a kite, though.
-* Commercial Flights: The 10 arc second rule means you need to be under 310 metres from the hashpoint. 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. Don't try to persuade the crew to alter course in your favour - that would be hijacking! --[[User:Sourcerer|Sourcerer]] ([[User talk:Sourcerer|talk]]) 16:25, 31 January 2018 (UTC)
