Risk analysis in the surrounding areas of one-runway airports: A methodology to preliminary calculus of PSZs dimensions
Full text linkThe risk analysis of aeronautical accidents has been faced in several countries in order to plan the territory around airports. In the past, many accidents have had serious consequences in the surrounding of airports. To protect the dwellers in these zones, Sapienza University of Rome has studied a risk assessment model of air crash accident during take-off or landing. In force of an agreement with the National Aviation Authority, the major Italian airports have been analyzed. These studies have highlighted the opportunity to know the influence on the territory of the variation of the traffic volume. This knowledge can be particularly useful for forecasting the impact on the territory in a preliminary phase of the master planning activity of the airport. The influence of the traffic volume and the types of aircraft on the sizes of safety areas around airports has been studied with a computer program developed by the authors. As a result of this first analysis, a simplified approach to study the extension of the Public Safety Zones around an airport is presented. This method calculates the area and the main dimensions of PSZs for a number of representative cases of one-runway airports with more than 30000 operations per year. In Europe, there are a large number of one-runway airports and they have similar operational and traffic conditions. Therefore, the results here presented can be applied for a preliminary study to all the one-runway airports, having the same level of traffic of the airports considered in this paper
La valutazione del rischio di incidente per svio dalla pista di volo
No full textL’analisi del rischio è finalizzata alla definizione della portanza della strip aeroportuale che “può diminuire gradualmente in direzione trasversale, verso l’esterno, per favorire l’arresto del velivolo”. Il piano di rotolamento interessato dal passaggio di un aeromobile uscito lateralmente dalla pista deve contribuire in modo sicuro ed efficace all’arresto del mezzo in condizioni di sicurezza. Nelle intenzioni della Normativa il corretto dimensionamento della portanza della CGA (Cleared and Graded Area) è perciò lo strumento per la mitigazione del danno e quindi del rischio in caso di incidente di veer-off, ovvero svio dalla pista di volo. Allo stato attuale, le dimensioni trasversali della strip e della CGA dipendono dalla strumentazione e dal codice numerico della pista. In questo studio si propone una valutazione delle attuali condizioni di sicurezza garantite dalla CGA dimensionata secondo la normativa vigente
