Development and Evaluation of a Tower Slant Visual Range System.

Abstract

Analysis of remote tower forward scatter meter measurements of extinction coefficient collected at the Air Force Geophysics Laboratory Weather Test Facility at Otis AFB, Massachusetts demonstrated the accuracy of a remote tower slant visual range (SVR) system. This report describes the final phase of the development and evaluation of a tower SVR system in which the remote tower approach has been extended to include Category I operations. Tests give additional evidence that the runway visual range (RVR) measurements are often not representative of pilot visibility during approach and touchdown. An examination of three short range prediction techniques for forecast times of 2, 5, 10, 30 and 60 minutes revealed that the Equivalent Markov technique provides accurate and reliable forecasts of below-limit SVR conditions and yields slightly better results than the Markov and REEP techniques.
