ANALYSIS OF HELIPORT ENVIRONMENTAL DATA: INDIANAPOLIS DOWNTOWN HELIPORT WALL STREET HELIPORT. VOLUME 2. WALL STREET HELIPORT DATA PLOTS

During the summer of 1987 heliport environmental data were collected at Indianapolis Downtown Heliport and at New York's Wall Street Heliport. The purpose of this data collection activity was to obtain measures of rotorwash in the heliport environment due to maneuvering helicopters, and to obtain pilot perceptions and observations concerning maneuvering and parking separation criteria. Ten wind vector transmitters were situated at various locations around the heliport in order to gather information to describe the rotorwash induced wind speed and direction changes. Pilot interviews were also conducted at these heliports. Volume 1 of this report provides a summary of the results of this activity. Volume 3 provides the plots generated from the wind sensor data collected at the Indianapolis downtown Heliport. This volume (Volume 2) provides the plots generated from the wind sensor data collected at New York's Wall Street Heliport. The results of this study will be considered in future modifications of the Federal Aviation Administration (FAA) Heliport Design Advisory Circular.
