A few weeks ago I flew CX531 from Taipei to Hong Kong. As I was leaving the A340-300 I noticed a golden, triangular sticker above the left window of a particular row. I looked across the aisle to the right hand side of the aircraft and saw the same sticker above the window of the same row. They appeared only in that particular row but not others. Wondering what function these stickers serve?

anstar's reply does make sense indeed. Any other airlines marking this position?
My first thought was it would mark some kind of emergency exit, i.e. where the window could be broken with the emergency equipment or so.
Saw a similar marking in Japan, where windows in big buildings are marked for this reason: http://www.chiikikagaku.co.jp/nippon/articles/image/230.jpg

Nah. That's what emergency exits are for. Anywhere else you'd need some sort of cutting equipment. Many planes have outside markings for that purpose though.

Quoting anstar (Reply 1): They indicate the best position for the flight crew to see the leading edge and trailing edge of the wing.
Let me add that it is the best position to inspect the wings for snow and ice.
Quoting Viscount724 (Reply 3): It's very common. I've seen that arrow on dozens of Airbus aircraft. Can't remember whether there's anything similar on Boeing aircraft.
I can't say I've seen any markings on a Boeing aircraft. Then again there might be a marking somewhere that is less noticeable than the airbus markings. The next time I am on a flight on a Boeing I'll have to look around to see if I can see anything.

That is partially correct. The triangles indicate the location of the leading and trailing edges of the wing. However ... that is not known to flight crew, as it is not indicated anywhere in the Flight Crew Operating Manual. So, as it is not "known" to the pilots, I have never known the use of these indicators, and have often wondered their use.

The best position would be ahead of the aft triangle, as the condition of the spoilers is especially important. On days where one would not think ice to be a factor, the spoilers can be "frosted" and that frost must be removed.
