Landing Safety Analysis of An Independent Arrival Runway

The growth of aviation traffic volume and the attempts to increase operational capacity by reducing aircraft spacing make aviation safety an urgent research issue in the aviation community. Simultaneous runway occupancy of landing aircraft is a precursor of a runway collision, and it is an effective of measure of runway landing safety. This paper presents an analytical method to evaluate the probability of a simultaneous runway occupancy using an M/G/1 queuing model. We conduct sensitivity analysis with the model to show the effects of reducing the mean and variance of runway occupancy time. The results show that landing safety can be significantly improved by reducing variance of occupancy time without changing the average length.
