Abstract: There is a great amount of uncertainty about what specific technique or classes of techniques ought to be used to prevent midair collisions. The purpose of this paper is to provide data to help resolve this uncertainty. First, a statistical analysis of recent midair collisions in the United States and of the pertinent factors surrounding these accidents is given. Next, three classes of midair collision prevention techniques are described briefly, highlighting their important strengths and weaknesses. These classes are: regulatory changes including structured or regulated airspace; introduction of an autonomous airborne CAS; and projected improvements to the ATC system. The statistical data from the first part of the paper are applied to these classes to estimate the fraction of fatalities and accidents that might be prevented. From this analysis, one can draw conclusions that suggest specific steps and ordering of steps that should and should not be undertaken in a sensible, unified program to reduce the incidence of midair collisions.
