Comparison of some methods to determine the delays of landing aircraft with respect to runway capacity

The capacity of runways in use for landing aircraft may become the chief bottleneck of the capacity of airports. This runway capacity may result in long queues of aircraft waiting for landing, which in its turn results in unacceptable delays. Two analytic methods to determine these delays are described and the results are compared. The two...

Estimating the probability of vertical overlap from the paired aircraft data obtained in the european vertical data collection using the program DGLDiF

The problem of estimating the probability of vertical overlap in possible future airway systems with a vertical separation standard of 1000 ft above Flight Level 290 is addressed. It forms part of an overall safety assessment of such potential systems. The problem is solved by developing a mathematical probability model of the vertical distance...

Historical development of collision risk models for en-route air traffic

This lecture reviews the model studies that were made with the object to reduce en-route separation standards. It also describes the basic principles of the Reich model used in most of these studies and of the Minimum Navigation Performance Specification (MNPS). Paper presented at the Princeton University Conference 155, "Safety Issues in Air...
