Performance Data Analysis and Reporting System (PDARS)

The Performance Data Analysis and Reporting System (PDARS) was a joint Federal Aviation Administration–NASA effort within the Aviation Safety Monitoring and Modeling Project. It developed technologies to monitor daily operations of the National Airspace System and to measure how Air Traffic Control delivered services, with the goal of ensuring safety, efficiency and responsiveness to customers.

PDARS gave facility-level managers tools to monitor system performance, pinpoint and analyze operational problems, and design and evaluate improvements. It enabled interconnected ATC facilities to collect, extract, process and merge ATC data; compute quantitative performance measures; disseminate performance reports; run system-design and simulation “what-if” studies; and archive basic operational data and performance statistics.

Key milestones included completion of a prototype network and demonstration, generation of daily reports, prototype evaluation, a design review and delivery of initial upgrades.
