Wing loading : ウィキペディア英語版 | Wing loading In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing.〔Thom, 1988. p. 6.〕 The faster an aircraft flies, the more lift is produced by each unit of wing area, so a smaller wing can carry the same weight in level flight, operating at a higher wing loading. Correspondingly, the landing and takeoff speeds will be higher. The high wing loading also decreases maneuverability. The same constraints apply to winged biological organisms. ==Range of wing loadings==
The table, which shows wing loadings, is intended to give an idea of the range of wing loadings used by aircraft. Maximum weights have been used. There will be variations amongst variants of any particular type. The dates are approximate, indicating period of introduction. The upper critical limit for bird flight is about 5 lb/ft2 (25 kg/m2).〔Meunier, 1951〕 An analysis of bird flight which looked at 138 species ranging in mass from 10 g to 10 kg, from small passerines to swans and cranes found wing loadings from about 1 to 20 kg/m2.〔http://www.biology-online.org/articles/flight-speeds-among-bird-species.html〕 The wing loadings of some of the lightest aircraft fall comfortably within this range. One typical hang glider (see table) has a maximum wing loading of 6.3 kg/m2, and an ultralight rigid glider〔BUG4 http://home.att.net/~m--sandlin/bug.htm〕 8.3 kg/m2.
