Abstract
Airlines can optimize surface operations using real-time surface surveillance data. The Federal Aviation Administration (FAA) Technology Development Office (formerly Safe Flight 21 and Surface Technology Assessment) began examining the operational impacts of surface surveillance data sharing in current and future FAA tools. This study investigates the operational impact of surface surveillance data provided to Federal Express (FedEx) at Memphis International Airport (MEM) through a joint FAA/National Aeronautics and Space Administration (NASA) project. We first use an unexpected loss of surface surveillance data as an opportunity to gauge impacts. The analysis measures changes in taxi-out times, queue lengths, and departure rates before, during, and after the surveillance outage. We repeat the analysis comparing a baseline period before implementation of surface surveillance with a post-implementation period. Analyses of both data sets displays a reduction in taxi-out times and indicates an increase in effective departure capacity (approximately 5–10 aircraft per hour greater) during times when surveillance was available.
