An aircraft seat map or seating chart, is a diagram of the seat layout inside a passenger aircraft. They are often published by airlines for informational purposes, and are of use to passengers for selection of their seat at booking or check-in. Seat maps usually indicate the basic seating layout, the numbering and lettering of the seats, the location of the emergency exits, lavatories, galleys, bulkheads and wings. Airlines which allow internet check-in frequently present a seat map indicating free and occupied seats to the passenger so that they select their seat from it. In addition to the published seat maps from airliners, there are a number of independent websites which also publish seat maps along with reviews of individual seats, noting the particularly good (extra legroom, quiet cabin, etc.) or bad (lack of recline, unusually cramped, missing window, etc.) seats. ==Seat maps published by airlines== Most of the airlines publish the seat configurations for their aircraft, but the quality of these seat maps is sometimes questionable. Some of the details and information about seats are confusing. Usually airlines do not publish seat maps for every aircraft, only for the larger aircraft and for the ones flying on frequent routes. When passengers complete an online booking, or check in online, they are often also presented with an aircraft seat map. However, this data is sourced from the original text-only seat maps on computer reservation systems such as Sabre where the seatmap is simply held as a two-dimensional array and as such can only display a grid of seats, as opposed to the more ingenious layouts now used in First and Business Class. Nichols et al. (2013) have reported that when people book seats on-line, they exhibit a leftward preference for seats on an aircraft, but a rightward preference for seats at the theatre.〔Nicholls, M. E. R., Thomas, N. A, and Loetscher, T., "An Online Means of Testing Asymetries in Seating Preference Reveals a Bias for Airplanes and Theatres", ''Human Factors'', Vol. 55, Issue 4 (2), August 2013.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aircraft seat map」の詳細全文を読む スポンサード リンク
