VISUAL APPROACH DATA COLLECTION AT SAN FRANCISCO INTERNATIONAL AIRPORT (SFO)

Abstract : Data on aircraft executing simultaneous visual approaches to parallel runways 28R and 29L were collected at San Francisco International Airport (SFO) between November 9, 1989 and March 12, 1990. The purpose of data collection was to analyze the navigational characteristics of aircraft flying the fly visual segment of the approach. Aircraft position data were collected using the in- place Bay Terminal Radar Approach Control Facility (TRACON) Airport surveillance primary and secondary radars. Data Reduction and limited analysis were done at the Federal Aviation Administration (FAA) Technical Center by ATC Technology Branch (ACD-340) personnel. The discussion in this concerns the accuracy of the collected position data and possible sources of error in the data collection. The reduced data will be sent to the Standards Development Branch (AVN-540) for further analysis. AVN-540 will conduct the final analysis of the data and report on their findings and recommendations.
