== Abstract ==&lt;br /&gt;
&lt;br /&gt;
Because of the potential increase in traffic at FL 290 and above, both current and alternative vertical separation standards are being reviewed. A plan to collect data on the vertical navigational performance of aircraft is also contemplated. This report documents a sensitivity analysis carried out to assess how different assumptions about the probability distribution of 'total vertical error' affect the probability of vertical overlap. The four factors affecting the probability of vertical overlap which are examined in this study are: the functional form of the vertical-error distribution function; the standard deviation of this probability distribution; the vertical dimensions of the aircraft; and the vertical separation standard. Probabilities of vertical overlap were computed over a range of possibilities for each of these four factors in order to discern the effect of each factor. A final section discusses the findings of this study and draws some conclusions.&lt;br /&gt;
