In this study, we propose a Simulated Annealing (SA) method to solve the problem of designing multiple Standard Instrument Departure (SID) routes and Standard Terminal Arrival Routes (STAR) in Terminal Maneuvering Area (TMA) with optimal lengths. This work extends our previous work (J. Zhou et al., 2015) for the design of one optimal route. The design of multiple routes addressed in this paper takes into account obstacle avoidance and routes separation as main constraints. Our preliminary numerical results show that the proposed SA method is effective in the generation of multiple routes in a TMA.

NASA's Unmanned Aerial System (UAS) Traffic Management (UTM) project aims at enabling near-term, safe operations of small UAS vehicles in uncontrolled airspace, i.e., Class G airspace. A far-term goal of UTM research and development is to accommodate the expected rise in small UAS traffic density throughout the National Airspace System (NAS) at low altitudes for beyond visual line-of-sight operations. This paper describes a new capability referred to as ICAROUS (Integrated Configurable Algorithms for Reliable Operations of Unmanned Systems), which is being developed under the UTM project. ICAROUS is a software architecture comprised of highly assured algorithms for building safety-centric, autonomous, unmanned aircraft applications. Central to the development of the ICAROUS algorithms is the use of well-established formal methods to guarantee higher levels of safety assurance by monitoring and bounding the behavior of autonomous systems. The core autonomy-enabling capabilities in ICAROUS include constraint conformance monitoring and contingency control functions. ICAROUS also provides a highly configurable user interface that enables the modular integration of mission-specific software components.

The German Aerospace Center (DLR) and the National Aeronautics and Space Administration (NASA) have been independently developing and testing their own concepts and tools for airport surface traffic management. Although these concepts and tools have been tested individually for European and US airports, they have never been compared or analyzed side-by-side. This paper presents the collaborative research devoted to the evaluation and analysis of two different surface management concepts. Hamburg Airport was used as a common test bed airport for the study. First, two independent simulations using the same traffic scenario were conducted: one by the DLR team using the Controller Assistance for Departure Optimization (CADEO) and the Taxi Routing for Aircraft: Creation and Controlling (TRACC) in a real-time simulation environment, and one by the NASA team based on the Spot and Runway Departure Advisor (SARDA) in a fast-time simulation environment. A set of common performance metrics was defined. The simulation results showed that both approaches produced operational benefits in efficiency, such as reducing taxi times, while maintaining runway throughput. Both approaches generated the gate pushback schedule to meet the runway schedule, such that the runway utilization was maximized. The conflict-free taxi guidance by TRACC helped avoid taxi conflicts and reduced taxiing stops, but the taxi benefit needed be assessed together with runway throughput to analyze the overall performance objective.

High demand of flights on elementary air traffic control sectors results in high delays, extra-fuel burn and CO2 emissions, and may also lead to safety issues due to the destabilization of the aviation network. This paper presents a new control strategy approach to keep control of the current flight demand in European busiest sectors (Reims, Paris and Marseille sectors). Flow management positions in Area Control Centers suggest to airline operations centers delay-free routes for the most capacity impeding flights within the French airspace. Instead of spreading flight demand over time, this innovative approach aims at spreading the demand in space, relying on local expertise and enhanced collaboration. The trials conducted from July to September 2015 proved to be beneficial for airlines operations with more than 12,000 minutes of delay saved compared to summer 2014 while traffic increased by more than 6% from 9h to 13h UTC. Following Airport-Collaborative Decision Making, the Collaborative Advanced Planning process paves the way for the En-Route Collaborative Decision Making concept.

To determine the capabilities and limitations of human operators and automation in separation assurance roles, a human-in-the-loop study investigated allocation of air traffic control functions across three different conditions where amount of automation and controller tasks were varied. Participants worked a single sector with aircraft in different phases of flight. Scenarios included varying levels of traffic and purpose-built conflicts, in a 3-by-2 condition design (task automation by traffic scenario). The premise of the study was that greater amounts of automation would reduce participant workload and increase performance (fewer losses of separation and greater schedule conformance). Findings showed that while workload did decrease, on average, the best system performance overall occurred in a condition where there was some but not full automation, suggesting the value of keeping a controller purposefully involved in air traffic control.

To reduce the risk of loss of control in-flight due to loss of attitude awareness, a new roll attitude alert was developed (Enhanced Bank Angle Warning). This alert consists of a moving red arrow on the primary flight display with a voice aural indicating the correct recovery action. The alert has two intended functions: (1) to increase the timeliness and likelihood of correct control input by the pilot flying, and, (2) to increase the timeliness and likelihood of intervention by the pilot monitoring (if the pilot flying fails to take appropriate actions). In the development of this alert, data on loss of control accidents and incidents were reviewed and various flight deck design elements were evaluated during prototyping for effectiveness in communicating aircraft state and recovery actions. Design elements studied included symbol shape, symbol motion, color, and the presence and content of voice aurals. Following prototyping, the ultimate design was evaluated in a pilot-in-the-loop simulation study with 19 airline pilots, including 5 non-native-English speakers. The two intended functions of the alert were tested in two scenarios: one intended to assess behavior of the pilot monitoring during an unexpected overbank condition and the other to assess behavior of the pilot flying in response to unusual attitude recovery scenarios. The results with respect to behavior of the pilot monitoring trended in a positive direction, but were not statistically significant. The results with respect to behavior of the pilot flying provide strong support for inclusion of the alert to improve pilot flying response to unusual roll attitudes. This paper reviews the prototyping phase, pilot-in-the-loop simulation results, and the challenges that were eventually overcome to implement the Enhanced Bank Angle Warning in Boeing's 737-MAX airplanes.

Although the Aeronautical Information Exchange Model (AIXM) and ICAO Weather Information Exchange Model (IWXXM) standards are quite mature, the implementation of those standards is open to interpretation. Differences between International Air Navigation Service Providers' (ANSPs) implementations have been observed during the development phase of the Mini Global (MG) Phase II project. These differing interpretations in the implementation of AIXM and IWXXM standards could jeopardize interoperability. This paper focuses on the observed differences and the solutions developed for the MG II demonstration for AIXM and IWXXM interoperability between the United States, Asia, Caribbean, Europe, and Middle Eastern regions.

Trajectory-Based Operations require the development and execution of a trajectory-based plan which is subject to uncertainty as a result of trajectory prediction inaccuracy and disturbances. The impact of disturbances due to conflict detection/resolution and traffic synchronization are evaluated under different levels of prediction inaccuracy through Monte Carlo Simulation. Conflicts are estimated to contribute uncertainty below a 1% speed variation for look-ahead times beyond 2 hours. Traffic Synchronization is shown to further amplify any trajectory prediction inaccuracy. A process for the incremental assignment of delays is described using an optimum delay margin and credit to ensure a stable delay is assigned. The approach is shown to allow a shift from costly tactical delays to strategic, equitably assigning delays across stage lengths and providing significantly more predictable delays per flight prior to departure. Benefits are shown to increase as trajectory prediction accuracy is improved.

The coming decade will see an unprecedented air traffic growth and the installation of more avionic systems onboard aircrafts, in response to new services, safety and reliability requirements. The latter has triggered the evolution of avionic architecture towards the next generation Integrated Modular Avionics (IMA), due to space constraints under the Federated architecture. Furthermore, newer avionic systems and communication requirements will exasperate data capacity demands in the already constrained spectrum. Therefore, the spectral efficiency of existing avionic communication systems must be improved or new high data capacity communications technologies must be identified that can coexist with other avionic radios in the saturated aeronautical bands. In this paper, the efficiency improvements to avionic communication waveforms and the IMA architecture are addressed. In particular, a new modulation technique is proposed for avionic waveform and is evaluated for aeronautic communication channels. Also, a concept for a more efficient architecture is proposed and discussed within the IMA second generation (IMA 2G) that integrates the communication, navigation and surveillance radios together with other avionic applications into an ARINC 653 standard, which supports a partitioned Operating System. This includes the integration of the avionic waveforms to run within an independent IMA partition. Optimization of applications in the overall IMA system framework will reduce the number of avionics hardware (IMA Modules). Reducing the number of avionics hardware, coupled with flexible or reconfigurable hardware, will result in reduced cabling and associated connectors, thus contributing to the reduction in the overall weight of the aircraft. This will consequently boost fuel efficiency from an avionics perspective.

This paper describes conflict resolution trials on worst case situations. Instead of using natural trajectories from real traffic scenarios, this paper investigates the solution of super-conflicts. These are generated by scheduling multiple aircraft through one common 4-dimensional point. All generated aircraft are planned to have identical latitude, longitude and altitude position for one moment in time. Using different setups for the super-conflict, the paper discusses several conflict resolution strategies (lateral, vertical and time-based) with their associated costs.
