Evaluation of Approach and Landing Factors Influencing Airport Safety

摘要

This exploratory study examined some of the factors that influence approach andlanding safety at principal international airports, especially as regards the influence on risk of fully-functioning precision terminal approach and guidance equipment. The objective was to quantify the degree to which these factors are associated with the risk of an accident. Accident and movement data for 557 ICAO Principal Airports for decade 1984-1993 were evaluated for the risk analysis. The accident sample comprised 132 hull loss occurences. The study concludes that precision approaches confer a risk advantage of about five over non-precision approaches absent other factors on a world-wide basis.
