Paper 28 -- Airline Operational Benefits Of Surface Surveillance

Airlines can optimize surface operations using real-time surface surveillance data.The Federal Aviation Administrations Air Traffic Organization (ATO) Technology Development Team (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 examines taxi time and departure rate benefits of surveillance data for airlines using two examples. The first example investigates the operational impact of 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 using a baseline period and a post-implementation period.Both data sets display a reduction in taxi-out times and indicate an increase in effective departure rates (approximately 3 aircraft per hour greater) during times when surveillance was available.The second example examines the impact of data provided to the Delta Air Lines ramp tower at Dallas-Fort Worth International Airport (DFW).We find a decrease in Delta taxi-out times relative to airport surface queues after implementation and compared with airlines not using surface surveillance.
