Wing loading

In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing. 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.
