AbstractThe correct planning around airport safeguard the territory from risks of air accidents. Most of accidents are localized along the extended runway centerline and, for this reason, the Land Use compatibility Plans have been defined just in the areas after the thresholds. Nevertheless, in the past, there have been also several events localized in runway lateral zone, so ENAC and Sapienza-University of Rome implemented a data-base of air accidents occurred in last 15 years all over the world, to analyze the occurrence of these events and to define the extension of the safety area on ground and around the runway.
