Economic Analysis of Local Area Augmentation System and Alternative Architectures.

Abstract

The objective of this study has been to perform an economic comparison by conducting a cost-benefit analysis (CBA) of five Local Area Augmentation System (LAAS) and alternative architectures. The five architectures chosen by the FAA for the study are: Pseudolite Kinematic LAAS, Wide-Lane Kinematic LAAS, Code-Based LAAS, instrument Landing System (ILS), and the LAAS-Glide Slope System. A comparison of architectures based on the benefit/cost (B/C) ratio and cost- effectiveness criterion indicates that the Code-Based LAAS architecture has, by far, the highest B/C ratio of 4.0 and the lowest life-cycle cost of $860.9 million over a 15-year time horizon. The B/C ratios of other non-ILS architectures are in the range of 3.4 to 3.7, and the life cycle costs in the range of $946.5 million to $1,014.6 million. For the reference ILS architecture, the study estimates a low B/C ratio of 0.4 and the life cycle cost of $921.2 million. The Latter cost is not much different from other architecture life cycle costs, despite the exclusion of the substantial sunk cost of existing runway ILS and aircraft avionics equipment.
