As NextGen concepts move toward increasing en route and terminal throughput, wake turbulence separation may become a limiting factor in the pursuit of capacity improvements. Better knowledge of the probable location of wakes (for air traffic controllers as well as pilots) could help provide safe separation from wake turbulence while avoiding unnecessary restrictions to operations. The Wake Turbulence Avoidance Automation (WTAA) research project, performed under MITRE's Mission Oriented Investigation and Experimentation (MOIE) work for the Federal Aviation Administration (FAA), demonstrated the use of existing FAA and the National Aeronautics and Space Administration (NASA) wake turbulence research and algorithms to estimate wake characteristics given specific aircraft and meteorological data. This capability was used to drive displays of wake information on pilot Cockpit Displays of Traffic Information (CDTIs). This paper provides an overview of the existing FAA and NASA wake research that was leveraged and describes the development of the wake tool and the methods used to provide wake situational awareness to flight crews. Feedback obtained from the human in the loop (HITL) simulations is discussed and recommendations for further development and incorporation of FAA and NASA advances in wake research are provided. For one arrival procedure developed during the research, an analysis of the capacity impact at individual airports and an estimate of the system-wide delay impact of possible arrival procedures enabled by these wake tools is presented.

Stream management is a novel air traffic control operational concept in which controllers control streams of aircraft that are functionally equivalent, rather than being responsible for “aircraft in airspace.” One of the potential benefits of stream management is workload reduction for the same amount of aircraft handled. An adaptation of the dynamic density workload measure was used to evaluate stream management operations against current sector based control. This evaluation is completed using FACET software and ASDI data. Stream visualizations and data analysis demonstrate the advantages of stream operations.

During development of revised international standards for the Aircraft Surveillance Applications (ASA) System RTCA Special Committee 186 Working Group 4 (SC-186 WG4) learned of operational cases of Traffic Information Service - Broadcast (TIS-B) track identifier changes (i.e., a discontinuity) across en route service volume boundaries. If not modified the preceding standards for airborne surveillance processors would allow generation of multiple coexisting airborne tracks for individual aircraft and corresponding symbols (graphical representations of these tracks) on cockpit traffic displays. Analysis and characterization of operational data indicated that up to three TIS-B tracks with different identifiers could be generated for a single aircraft within a short time period (e.g., 30 seconds). A high fidelity simulation of the ASA system (airborne processor and display) was used to show that during periods of track coexistence significant display symbol shadowing and divergence could occur. These characteristics, especially when pertaining to multiple aircraft within range of ownship, posed a potential problem of misleading information being presented to flight crews. RTCA SC-186 WG4 determined that a new function, intra-source TIS-B to TIS-B track correlation, was required for airborne surveillance processors. In support of this decision, the MITRE Corporation's Center for Advanced Aviation System Development (CAASD) developed algorithms for this function that instantaneously detect TIS-B track identifier changes and suppress display shadows to ensure flight crew perception of track continuity. This paper describes the analysis and characterization of the problem, development of an airborne algorithmic solution, formulation of strenuous test cases based on operational data, simulation of the TIS-B to TIS-B correlation function, and evaluation of its performance.

When airport arrival slots are scheduled in excess of the available capacity, the scheduled flights are assigned slots by a rationing scheme. The traditional approach is to ration slots by schedule (RBS) on a first-scheduled/first-assigned basis. This approach, although meeting equity criteria, can result in inefficient use of the arrival slots in terms of passenger throughput and fuel burn; however, it does not reflect the business decisions with respect to the value of a given flight to an airline. An alternative approach is to allocate the slots based on an airlines' willingness-to-pay a congestion fee, set a priori by a regulator, for use of the slot. This paper describes a comparison of the allocation of arrival slots using RBS and Congestion Pricing (CP) for flights scheduled into PHL on 10-Jul-2007. The analysis indicates that rationing by CP yielded improved performance in the reduction of average passenger delays by 39.14%, total Passenger Delays by 37.65% and cancelled flights by 66.66% (9 cancellations in RB to 3 cancelled flights in CP). However, rationing by CP decreased average airline equity metric by 34.81%.

Frequent cross strait flights have made Taipei Terminal Control Area (TCA) into flow congestion and conflict threat. A flow monitor is proposed to provide the predicted sequence of inbound and outbound aircraft with minimum separation in the intersected 10 NM airport circles in Taipei TCA. The flight data processor (FDP) data from system analysis record (SAR) are applied to estimate the time of metering fix until landing. Air traffic control (ATC) indicates vectoring aircraft according to predict sequence by executing ground holding and speed adjustment to avoid airborne holding or conflict. Based on daily schedules and their FDP, flow monitor is designed to forecast the future 60 minutes of inbound flights and to ease possible congestion within 30 minutes in Taipei TCA. Dynamic rescheduling is applied to change delay flights in flow queuing periodically. A case study is simulated to focus on current flow condition. The flow monitor can be used in approach control region and can efficiently reduce the probability of congestion in the busy TCA.

The increasing number of aircraft movements has caused aircraft noise to be perceived as a serious environmental problem. In order to reduce aircraft noise several noise optimized approach procedures, take-off procedures, and corresponding flight paths have been developed. In addition, several measures like night flight restrictions, noise preferential runways, bigger airplanes, quieter engines and noise contingent contributes have also been proposed for the reduction of aircraft noise. This paper discusses different sources of flight trajectories that can be used for noise calculation and analyses their advantages and disadvantages. On this basis selected evaluation results of noise abatement procedures developed in a German government study are presented and discussed.

Air Traffic Flow Management (TFM) is a collaborative process between the airspace provider (ATCSCC) and the airspace users (AOCs). The result of the collaboration should be an outcome that maximizes the utility of the system without excessively penalizing any of the agents. This paper describes the results of a tradeoff analysis between flight costs and sector throughput for combinations of ATCSCC and AOC strategies for flight-plan route selections in the presence of weather that affects enroute airspace capacity. The analysis is conducted using a discrete event simulation model of an airspace network with several airports, sectors and alternative airways. The results of the analysis indicate that when both Miles-in-Trails (MIT) restrictions for the airspace, as well as, TFM rerouting in collaboration with the AOC takes place, the performance of the overall system achieves a reduction of 67% in delay costs, 61% in delay time, 22% in delay rate and 69% in total passengers delay time (compared to the baseline). The implications of the results are discussed in this paper.
