Continued Analysis of a Capacity Concept for Runway and Final-Approach Path Airspace.

摘要

In a previous study, a 'maximum throughput rate' concept for the capacity of a runway and its associated final-approach path airspace was developed, represented by a simple mathematical formula, and given illustrative application in the context of a stream of IFR CTOL landings. The present report continues this line of investigation. The capacity formulation is generalized to admit aircraft-type-dependent separation minima. Algebraic tests are developed to aid in identifying both those situations in which in-air separation requirements are the dominant limiters of capacity, and the opposite extreme in which long occupancy of the runway by arriving planes is the critical bottleneck. Simplified upper bounds on (numerical) capacity are derived. An analysis is made of the capacity-increasing potential of certain types of deviation from first-come-first-served acceptance of aircraft. (Author)
