Memphis International Airport (MEM) is the busiest cargo airport in North America (second in the world), with 4,137,938 metric tons (4,551,732 U.S. tons) passing through its facilities in 2013. It is the home of the FedEx Express global SuperHub, which processes a significant portion of the freight carrier's packages.

Several NextGen capabilities and enabling improvements have been implemented, including Airport Surface Detection Equipment — Model X (ASDE-X), Performance Based Navigation (PBN) procedures, Wake Re-Categorization, basic rerouting and Time Based Flow Management (TBFM).

All airport information shown above is reported by Calendar Year (CY); results in the table below are reported by Fiscal Year (FY), October 1 — September 30.

Efficiency Performance Indicators
Performance Indicator (FY) 2009 2010 2011 2012 2013
Average Gate Arrival Delay
Minutes per Flight

During reportable hours, the yearly average of the difference between the Actual Gate-In Time and the Scheduled Gate-In Time for flights to the selected airport from any of the ASPM airports. The delay for each FY is calculated based on the 0.5 — 99.5 percentile of the distributions for the year. Flights may depart outside reportable hours, but must arrive during them. The reportable hours vary by airport.

Effective Gate-to-Gate Time
Minutes per Flight

During reportable hours, the difference between the Actual Gate-In Time at the destination (selected) airport and the Scheduled Gate-Out Time at the origin airport. Flights may depart outside reportable hours, but must arrive during them. The reportable hours vary by airport and the results are reported by FY.

Taxi-In Time
Minutes per Flight

During reportable hours, the yearly average of the difference between Wheels-On Time and Gate-In Time for flights arriving at the selected airport from any of the Aviation System Performance Metrics (ASPM) airports. Flights may depart outside reportable hours, but must arrive during them. The reportable hours vary by airport.

Taxi-Out Time
Minutes per Flight

During reportable hours, the yearly average of the difference between Gate-Out Time and Wheels-Off Time for flights from the selected airport to any of the ASPM airports. Flights must depart during reportable hours, but may arrive outside them. The reportable hours vary by airport.

1 Consistent data for the time period prior to FY 2011 is not available.

As described by ICAO; efficiency addresses the operational and economic cost-effectiveness of gate-to-gate flight operations from a single-flight perspective. In all phases of flight, airspace users want to depart and arrive at the times they select and fly the trajectory they determine to be optimum.

Average Daily Capacity
Operations (arrivals plus departures)

During reportable hours, the average daily sum of the Airport Departure Rate (ADR) and Efficiency Airport Arrival Rate (Eff AAR) reported by FY. The reportable hours vary by airport. Additional ADR and Eff AAR information is provided in the Average Daily Capacity entry of the Reference Guide.
