According to an IATA survey, runway excursions accounted for 21% of all air accidents in 2010. Such accidents dropped by 13% in 2010 though. Two leading causes of runway excursions were landing on wet runways and landing in an unstable approach, aircraft approaching too fast, too high, or touching down beyond the appropriate touchdown point. Asia-Pacific carriers recorded a 9% year-on-year increase in passenger demand in 2010. Corresponding figures for North America and Europe were 7.4% and 5.1% respectively. Middle Eastern carriers reported the strongest growth among all regions at 17.8%.
