On-Time Performance ASPM Non-Parametric Statistical Analysis

The purpose of this analysis is to provide a data-driven examination of two selected flight metrics, i.e., (1) total taxi-out time and (2) actual off time minus scheduled off block time. More specifically, Aviation System Performance Metrics (ASPM) data were analyzed to determine any possible differences in CLT (Charlotte Douglas International Airport) departure flights on these two metrics when comparing pre-IADS (Integrated Arrival, Departure, and Surface Operations) against post-IADS metering operations. This was originally presented to the ATD-2 (Airspace Technology Demonstration-2) Analytics team in August 2018.
