Runway Excursion: A Problem

Landing and takeoff overruns, undershoots, and veer-offs account for most of the accidents that occur on or in the immediate vicinity of the runway.Accident statistics show that, from 1959 to 2009, 55% of the world's jet fatal aircraft accidents occurred during landing and takeoff phases of the flight and accounted for 51% of all onboard fatalities (Boeing 2010).Although in many cases the causal factors involve some type of human error, the conditions at the airport may contribute significantly to the probability and severity of the accidents.The purpose of this study was to collect the data of runway excursion accidents and find out the reason how and why they happen.We have mainly focus on contamination of runway.
