Reason: The diagram is misleading, incomplete, and incorrect. Compare to https://upload.wikimedia.org/wikipedia/commons/0/06/Airport_Traffic_Pattern_with_Upwind_Leg.svg which correctly places the upwind leg.

Comment According to the Pilot's Handbook of Aeronautical Knowledge (Chapter 13, page 12-13) and the Aeronautical Information Manual (4-3-1, Components of a Traffic Pattern), 75.210.97.82 is correct in stating that this image is not accurately labeled. I've included a depiction of left and right hand traffic patterns found in the Handbook. The leg of the pattern labeled "upwind" is actually defined as the "departure" leg. --auburnpilot talk 18:33, 7 April 2013 (UTC)[reply]

Comment. Don't know it it was the right thing to do (and shoot me if it wasn't) but I edied the source file on the Commons to change "Upwind" to "Departure" and tidied the 3D shadow effect a little. — Cheers, Steelpillow (Talk) 19:34, 7 April 2013 (UTC) [Updated] Happy to make any other changes needed, e.g. adding the upwind loop, if any get agreed here. — Cheers, Steelpillow (Talk) 19:39, 7 April 2013 (UTC)[reply]
Unsure Are we certain we're not just enforcing an American bias, by insisting on American terminology, or is upwind called departure worldwide? Adam Cuerden ^(talk) 21:10, 7 April 2013 (UTC)[reply]
- It would be slightly odd if the "departure leg" was referred to as "departure" when the aircraft flying it was not departing. Both terms are correct, depending on context; an aircraft taking off or making touch-and-goes would make "departure" correct, while in the latter case it could also be "upwind" - as it would be for an aircraft arriving and making a full pattern. - The Bushranger _{One ping only} 22:44, 7 April 2013 (UTC)[reply]

I've heard both depending on the activity of the aircraft. The terms crosswind, downwind, base, and final are in seemingly universal usage. The upwind/departure leg doesn't seem to have worldwide agreement. The European Aviation Safety Agency has a document that includes a diagram remarkably similar to the original image on which this SVG is based (page 33). In that document, it is referred to as upwind with no mention of departure. A document from the UK based flying school Purple Aviation has the leg labeled as both upwind and departure (page 2). The Civil Aviation Safety Authority (Australia) doesn't label the leg on anything I could find (page 11 for an example). The Civil Aviation Authority of New Zealand refers to it as the "climb out" and labels it as such on their diagrams (pages 5 and 6). --auburnpilot talk 22:53, 7 April 2013 (UTC)[reply]

Calling Departure Upwind is wrong for the same reason that Final is not called Upwind: They are not the same place in the pattern. Yes, Departure is called Upwind by some non-professional pilots; but these same pilots use other incorrect terminology for other things, so that is no basis to mislabel a diagram. Yes, this could be US-centric terminology. So why not just include the official FAA version for what it is and the EASA version for what it is? There are other problems with this diagram being incomplete. Just changing one label does not correct the whole problem. With public domain versions available, I see no reason to reinvent a diagram. If another diagram is needed beyond the FAA and EASA versions, it should be a super-simplified version that omits all entries and exits from the pattern.
