abstract="This paper presents a new model for rating severity of losses of standard separation between aircraft in controlled airspace. FAA safety analysts currently use three categories of severity ratings, A through C, with A being the most severe and representing the closest proximity of aircraft to one another. The boundaries between the three are set arbitrarily, however, and that they cannot be combined to make meaningful comparisons across time periods, airports, weather situations, types of aircraft, etc. The proposed model provides a better way to rate the severity of individual separation violations because it produces a continuous severity measure rather than separating them into categories. It is inherently a ratio scale rather than an ordinal scale which permits averaging over time periods, airports or airspace regions, day or night operations.<p /><p>Language: en</p>",
