Future flight Schedules are generated based on air traffic demand forecast for the purpose of aviation planning and performance analysis studies. A selection process needs to be designed and implemented by sampling historical operational data for each fiscal quarter and choosing representative days that best reflect seasonality in terms of a given set of(More)
Air traffic management analysis efforts today are focusing more on trajectory-based operations as a basis for better air traffic control and modernization. Developing proper indicators that correctly characterize these operations has been a key activity for both EUROCONTROL and the FAA. Both organizations are working jointly towards harmonizing the(More)
The FAA's Air Traffic Organization (ATO) Office of Performance Analysis is responsible for developing indicators and providing analysis on the operational efficiency of the NAS and to ensure its databases provide the necessary information for linking performance to root causes. The focus of this paper is the primary indicator of capacity within a sector,(More)
The FAA and EUROCONTROL have a long history of collaboration on air traffic management performance measurement and benchmarking. Every couple of years this results in the joint publication of their report US/Europe Comparison of Air Traffic Management Related Operational Performance.
Simulation models are often employed to evaluate projected future performance of the US National Airspace System (NAS) for the purposes of long-term aviation investment planning and performance benchmarking. The future schedules are developed as input for simulation to represent the forecast for airport operations. The itinerary structure of a future(More)
In this paper, we present a Mixed Integer Programming formulation for the sample day selection problem. This formulation incorporates the IMC delay minutes for the purpose of modeling the effect of weather conditions in its objective function along with other performance metrics. The objective of the MIP formulation is to minimize the sum of differences(More)
Significant efforts are underway to modernize global air traffic management systems. Flight efficiency is a major political design criterion. This paper addresses the identification and measurement of ATM related constraints on vertical flight efficiency with a focus on continuous descent operations. Efficiency of flight operations has become a key driver(More)
