Airport Public Safety Zones: Part 2 - Risk Model Application

摘要

The purpose of airport Public Safety Zones (PSZs) is to protect the public on the ground from the small, but real possibility that an aircraft might crash in a populated area. Essentially, a PSZ is used to prevent inappropriate use of land where the risk to the public is greatest. The setting of PSZs has, until recently, been largely based on obstacle clearance areas. However, recent risk modelling has demonstrated that such zones do not encompass all the areas of greatest risk to the public. Such a risk model and its implementation as a software code is described in part one of this two part paper. This paper (part two) illustrates some typical results and summarises the development of criteria and guidance on behalf of the Irish government.
