Abstract
This paper presents the results of several analytical studies performed to provide information on computed centerline operations using Microwave Landing System (MLS) Area Navigation (RNAV) equipment. These studies addressed several issues. These issues included factors effecting positional accuracy, use of elevation information, and computed signal quality.
Analytical results were obtained with Monte Carlo simulation techniques which used the International Civil Aviation Organization's (ICAO) azimuth, elevation, and precision distance measuring equipment (DME/P), path following error specifications and signal degradations in Annex 10 to the International Standards, Recommended Practices and Procedures for Air Navigation Services. Data collection flights were performed at the Federal Aviation Administration (FAA) Technical Center in Atlantic City, New Jersey to validate the analytical results. During these tests the azimuth station was offset 500 and 1000 feet from the runway centerline. Results of these studies indicate that category I computed centerline operations could be conducted across a wide range of MLS siting conditions.
