What is PDARS?

The Performance Data Analysis and Reporting System (PDARS) is a fully integrated performancmeasurement tool designed to help the Federal Aviation Administration (FAA) improve the NationAirspace System (NAS). PDARS is a collaborativeffort between the FAA Office of Performance Anand Strategy and the National Aeronautics and SAdministration (NASA) Aviation Safety Program (AvSP). PDARS is being developed and manageATAC Corporation in Sunnyvale, California.

PDARS Cited Data

The PDARS data cited in the North Shore Helicopter Route 

Analysis represents VFR aircraft operating along the noshoreline of Long Island, New York. Those aircraft operaclear of Class B and Class C airspace did not require ATclearance. Aircraft operating within the Mode-C veil are required to be equipped with automatic pressure altitude rep

equipment having Mode C capability. 

Two groups of aircraft are represented in this evaluation, aircraft w

discrete beacon code (helicopters) and non-discrete beacon c(VFR aircraft on 1200 codes) :

1. Discrete Beacon Codes- Helicopters electing to receive Termi

VFR Radar Service provided by New York TRACON (N90) in Westbury, NY. The types of helicopters are identified by call sihelicopter type listed in JO 7110.65U, or as a generic “Helo” tyThe actual aircraft type can be determined by cross referencincall sign to an FAA database.

2. Non-discrete beacon codes- VFR aircraft on 1200 codes. The

aircraft did not elect to receive Terminal VFR Radar Service pby N90 (New York TRACON) in Westbury, NY. They were selbecause these flights follow a path consistent with the known helicopter traffic of similar speed. No attempt to differentiate bhelicopters or fixed-wing aircraft was made at this time. These aircraft are mode C equipped, squawking 1200 on their transpand displaying altitude information. There was no aircraft typeor destination determined.
