This paper presents a model and methodology for a safety and sensitivity analysis of the Advanced Airspace Concept. This analysis is part of a larger effort to analyze safety-capacity tradeoffs in NextGen concepts. A key part of the model is the definition of a dynamic event tree, which is like a standard event tree, but also includes the dimension of time in the state-space description. The model is constructed and evaluated in an automated fashion based on a set of input tables. Thus, changes to the model are easily implemented and results are automatically recomputed. The analytical implementation can be evaluated fairly quickly (a couple seconds per evaluation). A systematic sensitivity analysis shows that the transponder failure probability is a critical model parameter.

A data set is being assembled to describe the nature and extent of avionics equipage on aircraft that operate in the National Airspace System. This data helps inform decision making processes for how best to achieve the goals of NextGen. The MITRE Corporation's Center for Advanced Aviation Systems Development (CAASD) has spent several years developing this resource and refining the information management practices that sustain it. The resulting CAASD Avionics Information Repository for NextGen (CAIRN) is described and representative output products are presented.

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 between the sample averages and the full population averages. A variant of this formulation is also developed by adopting a weighting scheme based on the significance of IMC impact on the airports. Numerical results are reported and analyzed to show the effectiveness of this formulation and different choices of weighting schemes. Comparisons with the original model without IMC delay data are also presented.

This paper describes the mobile application that has been developed at the Embry-Riddle Aeronautical University (ERAU) Next-Generation ERAU Applied Research (NEAR) Laboratory. ERAU Multi Information Display (EMID) displays surveillance information based on Automatic dependency Surveillance Broadcast (ADS-B) standards used in FAA Next-Generation Air-Traffic Management (ATM). The initial version of the EMID was developed at the request of the ERAU flight department, for the purpose of monitoring the university fleet of over 75 ADS-B equipped aircraft. The later version of the EMID had incorporated additional functionalities to provide a platform for test and evaluation of new concepts in ATM and National Airspace (NAS) Usage. One of the advantages of the EMID is the use of SWIM (System Wide Information Management) like architecture, which allows the display of ADS-B and TIS-B aircraft position data received from SWIM-like surveillance services. ADS-B and TIS-B aircraft are represented by symbols that have optional data blocks capable of displaying altitude, speed, heading, and latitude/longitude information. EMID uses a different color coding scheme to distinguish between the commercial (blue) and general aviation (green) traffic. This color coding scheme has proven to make the product more user friendly, and reduce the overall workload of the user in identifying potential en-route conflicts. A mobile device version of the EMID called iEMID, has been developed using iOS [1] which can be deployed on iPhone and iPad devices. iEMID is a mobile Geographical Information System (GIS) based application capable of displaying geospatial referenced data. It supports pan and zoom and allows the user the capability to turn on/off different data layers. iEMID is capable of displaying high fidelity ESRI shape files of airspace volumes and airport layouts for precise tracking of aircraft while taxiing on the airport surface. This paper will concentrate on the overall functionality of the EMID and iEMID, and discuss some of the advantages and disadvantages of the product. We will also discuss the supporting infrastructure that is needed to allow system functionality. For example, the ADS-B surveillance service hosted at the NEAR lab that manages several ground receivers.

LDACS1 is a candidate for the future digital aeronautical communications system in L-band. As unused spectrum is very scarce in the L-band, LDACS1 pursues the approach to make use of the gaps between adjacent channels used by the distance measuring equipment (DME). This DME signal has a severe influence on the performance of LDACS1. In this paper, an algorithm for modeling the DME impact on LDACS1 is presented. This enables to determine whether LDACS1 can cope with DME interference for a certain area and channel frequency. The performance evaluation is based only on the positions, pulse rates, and transmit frequencies of the DME stations, without carrying out extensive simulation. Results for Europe indicate that a reliable operation of LDACS1 can be achieved.

AeroMACS (Aeronautical Mobile Airport Communications System), which is based upon the IEEE 802.16e mobile wireless standard, is expected to be implemented in the 5091-5150 MHz frequency band. As this band is also occupied by Mobile Satellite Service (MSS) feeder uplinks, AeroMACS must be designed to avoid interference with this incumbent service. The aspects of AeroMACS operation that present potential interference are under analysis in order to enable the definition of standards that assure that such interference will be avoided. In this study, the cumulative interference power distribution at low earth orbit from AeroMACS transmitters at the 497 major airports in the contiguous United States was simulated with the Visualyse Professional software. The dependence of the interference power on the number of antenna beams per airport, gain patterns, and beam direction orientations was simulated. As a function of these parameters, the simulation results are presented in terms of the limitations on transmitter power required to maintain the cumulative interference power under the established threshold.

The concept of Trajectory-Based Operations (TBO) is a cornerstone of the FAA NextGen CONOPS and the mid-term concepts of Trajectory Operations (TOps) will provide the path to TBO's far-term capabilities. These concepts of operation and use require a unified approach to bring both CNS and ATM capabilities together into effective methods and approaches for managing National Airspace System (NAS) throughput using individual 4D Trajectories across each phase of the trajectory lifecycle. Enabling of TOps/TBO requires interactive and integrated decisions and control actions spanning each time horizon to include Capacity Management, Flow Contingency Management, and Trajectory Management. This implies greater data access and common situational awareness than presently available in the highly probabilistic models of current NAS non-critical systems and deterministic models of critical systems. The FAA can accelerate the opportunities promised by Next Gen by providing a modern infrastructure, suitable to enabling TBO. A critical requirement is the Air Navigation Service Provider (ANSP) enabling NAS stakeholder access and common situational awareness of NAS capacity and congestion realities, both present and predicted states. This system, a Common Trajectory Planning Resource (CTPR), should provide operators a common interface to trial plan potential trajectories against NAS constraints via automation with operator's NextGen flight planning and tracking systems. CTPR should also monitor and provide updates on the traffic flow impacts to filed flights and proposed trajectories allowing operators to identify and choose the most optimum solutions available based on their own unique business model and operations. Trajectories themselves, embodied in flight plans, represent an intersection of NAS stakeholder and ANSP interests. These interests must be brought into alignment for the realization of TBO benefits. Providing airspace users with access to a new, Common Trajectory Planning Resource model is a key to unlocking TOps/TBO benefits. The highest level of NAS benefits will accrue when optimization is left in the hands of the operators, and market forces are allowed to reward positive behavior. This empowerment of operators by the ANSP as well as common visibility among all parties also offers the opportunity for satisfaction of each operator's own business objectives and will accommodate the widest diversity of business rules and plans among an increasingly heterogeneous and dynamic community of operators.
