PDARS is a collaborativeeffort between the FAA Office of Performance Analysisand Strategy and the National Aeronautics and SpaceAdministration (NASA) Aviation Safety Program(AvSP). PDARS is being developed and managed byATAC Corporation in Sunnyvale, California.Federal AviationAdministration3Explanation of North ShoreHelicopter Route AnalysisThe PDARS Tool SuitePDARS is several applications functioning inconjunction with one another. Each tool (or “module”)provides quantitative and/or graphical data aboutflights (see next slide)The primary PDARS tools include:• Microsoft Excel• BWRS (Excel-based reports, histograms, and charts)• GRADE (an advanced graphical displayenvironment)Federal AviationAdministration4Explanation of North ShoreHelicopter Route AnalysisThe PDARSTool SuiteMicrosoft Excel• BWRS (Excel-basedreports, histograms,and charts)• GRADE (anadvanced graphicaldisplay environment)Federal AviationAdministration5Explanation of North ShoreHelicopter Route AnalysisVoluntary Helicopter RouteRoutedefinedbywaypointsandLongIslandNorthShoreeastofPortJeffersonstacksVPROKVPLYDVPJAYNY Class B Airspacehttp://aeronav.faa.gov/content/aeronav/heli_files/New_York_Heli.zipFederal AviationAdministration6Explanation of North ShoreHelicopter Route AnalysisAirspace around Long IslandCLASS BClass CClass DSurf- 2,500Class E700 ft abovesurfaceClass E for Airways 1,200ft above surface 4 nmeither side of airwayMode C VeilSurface to 10,000msl excludingClass Bhttp://aeronav.faa.gov/content/aeronav/tac_files/New_York_TAC_82.zipFederal AviationAdministration7Explanation of North ShoreHelicopter Route AnalysisAirspace Classificationhttp://www.faa.gov/library/manuals/aviation/pilot_handbook/media/PHAK%20-%20Chapter%2014.pdfFederal AviationAdministration8Explanation of North ShoreHelicopter Route AnalysisAirspace Requirementshttp://www.faa.gov/library/manuals/aviation/pilot_handbook/media/PHAK%20-%20Chapter%2014.pdfMode C Veil- The airspace within 30 nauticalmiles of NY Class B from the surface upward to 10,000 feet MSL.Unless otherwise authorized by ATC,aircraft operating within this airspace must be equipped with automaticpressure altitude reporting equipment having Mode C capability.Federal AviationAdministration9Explanation of North ShoreHelicopter Route AnalysisPDARS Cited DataThe PDARS data cited in the North Shore Helicopter RouteAnalysis represents VFR aircraft operating along the northernshoreline of Long Island, New York. Those aircraft operatingclear of Class B and Class C airspace did not require ATCclearance. Aircraft operating within the Mode-C veil arerequired to beequipped with automatic pressure altitude reportingequipment having Mode C capability.Two groups of aircraft are represented in this evaluation, aircraft withdiscrete beacon code (helicopters) and non-discrete beacon codes(VFR aircraft on 1200 codes) :1. Discrete Beacon Codes- Helicopters electing to receive TerminalVFR Radar Service provided by New York TRACON (N90) inWestbury, NY. The types of helicopters are identified by call sign andhelicopter type listed in JO 7110.65U, or as a generic “Helo” type.The actual aircraft type can be determined by cross referencing thecall sign to an FAA database.Federal AviationAdministration10Explanation of North ShoreHelicopter Route AnalysisPDARS Cited Data2. Non-discrete beacon codes- VFR aircraft on 1200 codes. Theseaircraft did not elect to receive Terminal VFR Radar Service providedby N90 (New York TRACON) in Westbury, NY. They were selectedbecause these flights follow a path consistent with the knownhelicopter traffic of similar speed. No attempt to differentiate betweenhelicopters or fixed-wing aircraft was made at this time. Theseaircraft are mode C equipped, squawking 1200 on their transpondersand displaying altitude information. There was no aircraft type, originor destination determined.
