The transformation to net-centric operations necessitates evaluation of existing avionics capabilities, identification of deficiencies of these avionics for net-centric operations, and evaluation of alternative avionics that can provide the needed capabilities. The global information grid (GIG) enables net-centric operations. The purpose of the GIG is to provide end users real-time or near-real-time access to multiple information sources ranging from airborne/satellite/ground sensors (video imagery and processed visual information/data) to databases. The end users in an aircraft view and interact with this information through the human system interface (HSI) or "smart" displays. The information is transmitted across a gigabit Ethernet onboard the aircraft that interfaces with multiple channels of a software programmable radio that acts as a hub in the GIG network, or onboard sensors and processors. This work presents the mandated capabilities, and the processes involved in determination of upgrades needed to achieve net-centric operations.

An extension boom is to be installed on the starboard side of the Space Shuttle orbiter (SSO) payload bay for thermal tile inspection and repairing. As a result, the Space Shuttle payload bay ultra high frequency (UHF) antenna has been under the boom. This study is to evaluate the space shuttle UHF communication performance for antenna at a suitable new location. To ensure the communication coverage performance at the proposed new locations, the link margin between the UHF payload bay antenna and extravehicular activity (EVA) astronauts (SSO-EVA) in the upper hemisphere at a range distance of 160 meters from the payload bay antenna was analyzed. The communication performance between Space Shuttle orbiter and International Space Station (SSO-ISS) during rendezvous was also investigated. The multipath effects from payload bay structures surrounding the payload bay antenna were analyzed. The computer simulation tool based on the geometrical theory of diffraction method (GTD) was used to compute the signal strengths. The total field strength was obtained by summing the direct fields from the antennas and the reflected and diffracted fields from the surrounding structures. The computed signal strengths were compared to the signal strength corresponding to the 0 dB link margin. Based on the results obtained in this study, communication coverage for SSO-EVA and SSO-ISS communication links was determined for the proposed payload bay antenna UHF locations. The radio frequency (RF) radiation to the orbiter docking system (ODS) pyros, the payload bay avionics, and the shuttle remote manipulator system (SRMS) from the new proposed UHF antenna location was also investigated to ensure the EMC/EMI compliances.

This paper demonstrates a successful application of wavelength division multiplexing (WDM) to the avionics environment to support analog RF signal transmission. We investigate the simultaneous transmission of four RF signals (channels) over a single optical fiber. These four analog channels are sequentially multiplexed and demultiplexed at different points along a fiber optic backbone to more closely emulate the conditions found onboard aircraft. We present data from the measurements of signal-to-noise ratio (SNR), transmission response (loss and gain), group delay that defines phase distortion, and dynamic range that defines nonlinear distortion. The data indicate that WDM is well-suited for avionic applications.

The Federal Aviation Administration (FAA) Free Flight Program individually deployed the user request evaluation tool (URET), traffic management advisor (TMA), and controller-pilot data link communications (CPDLC) to a limited number of air route traffic control centers (ARTCCs). Before deployment expands nationwide, it was important to identify any potential human factors issues that may arise due to the collocation of these tools at the controller's workstation. In this paper, we present the results of a high fidelity human-in-the-loop simulation we conducted to evaluate the impact of URET, TMA, and CPDLC collocation on air traffic controllers. We examined collocation issues with a "stovepipe" independent configuration where none of the tools were integrated or directly communicated with each other. Twelve certified professional controllers participated in the simulation working in two-person teams consisting of a radar (R-side) and data (D-side) controller. The most important collocation issue identified was that controllers had difficulty accessing important information on the D-side display when URET and CPDLC were both operational (i.e., display clutter). Although neither tool alone caused display clutter, both tools in combination made it difficult for D-side controllers to find the information they needed quickly. This was especially true for accessing CPDLC windows, which became covered when controllers used URET. Good human factors design principles prescribe that users must have immediate access to important information and that critical information should never be covered. A "stovepipe" independent deployment of these tools will result in impaired access to timely information. The results of this study indicated that better efforts should be made to integrate the information from URET, TMA, and CPDLC on the D-side monitor prior to deployment of all three tools at the controller's workstation.

NASA's FACET (future ATM concepts evaluation tool) is a software package that predicts air traffic patterns. Such predictions are of potential value to a number of decision makers in the National Airspace System (NAS), including FAA traffic managers and airline dispatchers. In the study to be reported here, data was collected to: 1) Identify uses of the functions embedded in FACET for Airline Operations Centers (AOCs), 2) Determine enhancements of FACET (in terms of its underlying functionality or its interface) that might better support the needs of dispatchers and air traffic control coordinators at AOCs. To address these goals, a series of structured interviews with practicing airline dispatchers were conducted. As part of these interviews, the participants were introduced to the current capabilities of FACET and asked to consider: 1) Potential uses of the functionality contained in FACET for AOCs, 2) Potential extensions of the functionality of FACET to enhance its use by AOCs, 3) Potential enhancements in the interface design of FACET to better support AOC tasks. A total of 19 dispatchers were interviewed, representing experience at 5 different airlines and the US Air Force. The findings fall into five categories: 1.) AOC tasks that could make use of FACET, 2.) Using FACET to predict which flights are moved by ATC/TFM, 3.) Adapting FACET to support different AOC/Dispatch strategies Combining FACET trajectory predictions with other available data. Developing task-specific interface designs to support AOCs.

This work presents a combined statistical and adaptive approach for the verification of an adaptive, online learning, sigma-pi neural network that is used for aircraft damage adaptive flight control. Adaptive flight control systems must have the ability to sense its environment, process flight dynamics, and execute control actions. This project was completed for a class in complex adaptive systems at Nova Southeastern University. Verification of neural-based damage adaptive flight control system is currently an urgent and significant research and engineering topic since these systems are being looked upon as a new approach for aircraft survivability, for both commercial and military applications. The most significant shortcoming of the prior and current approaches to verifying adaptive neural networks is the application of linear approaches to a non-linear problem. Advances in computational power and neural network techniques for estimating aerodynamic stability and control derivatives provide opportunity for real-time adaptive control. New verification techniques are needed that substantially increases confidence in the use of these neural network systems in life, safety, and mission critical systems.

One of the distinguishing characteristics of the "free flight" concept is the sharing of aircraft separation responsibility between the pilot and the air traffic controller. In order to fulfill this responsibility, pilots will need to reliably detect and resolve conflicts as air traffic controllers do today. While there has been research on how air traffic controllers do this task, little is known about how pilots might do it. In particular, how pilots conceptualize the surrounding airspace and the relationships between their own aircraft and other aircraft may influence their decision making and the kinds of decision support they may need. In this study, fourteen pilots were given a series of short conflict scenarios that they had to resolve with and without the assistance of a cockpit display of traffic information that included an embedded conflict avoidance decision aid. Pilot success at resolving conflicts with and without the aid was measured. Pilots were also asked to rate airspace complexity, task difficulty, and aid acceptability. It was found that pilots performed significantly better with the aid, and that they rated the usability and value of the aid highly. A neural network model was then used to associate the measures of airspace complexity, derived from the spatio-temporal relationships between the pilot's ownship and other aircraft in the vicinity, to the pilot ratings of airspace complexity. The resulting analysis revealed the combinations of complexity measures that likely influence pilot perception of airspace complexity. Based on these results, a set containing eleven factors that appear to be most influential has been identified. Understanding of these factors may help designers of future air traffic management systems design conflict decision aids from a pilot's perspective that are likely to be more predictable and acceptable to pilots.

Interactions among airborne and terrestrial elements in an aeronautical environment may be enhanced by using common mechanisms for data transport and information management. These mechanisms can support a variety of applications, such as controller-pilot communications, surveillance, scheduling, traffic management, airline operations and others that vary widely in their respective requirements for security, performance and availability. This work presents an architectural framework for system-wide information management (SWIM), providing common data transport and information management services in an air traffic management environment. Although, the architecture is potentially global in scope, the focus of this work is the national airspace system. The Internet protocol family with common off-the-shelf technology and products can provide the necessary functionality and service characteristics - security, performance and availability - in a realizable and cost-effective manner for SWIM. This paper begins with a description of the SWIM environment before addressing the primary architectural issues and approaches in creating SWIM using common Internet protocol (IP) standards. Among the key aspects addressed are routing, mobility, security, compatibility with legacy onboard aircraft networks, support for varying quality of service (QoS) classes, multicast and information management. A list of acronyms and a reference list follow the presentation.

The integration of remotely piloted vehicles (RPVs) into civil airspace requires new methods of ensuring aircraft separation. This work discusses issues affecting requirements for RPV traffic avoidance systems and for performing the safety evaluations that are necessary to certify such systems. The paper outlines current ways in which traffic avoidance is assured depending on the type of airspace and type of traffic that is encountered. Alternative methods for RPVs to perform traffic avoidance are discussed, including the potential use of new see-and-avoid sensors or the traffic alert and collision avoidance system (TCAS). Finally, the paper outlines an established safety evaluation process that can be adapted to assure regulatory authorities that RPVs meet level of safety requirements.

Finally, the paper outlines an established safety evaluation process that can be adapted to assure regulatory authorities that RPVs meet level of safety requirements.","PeriodicalId":422463,"journal":{"name":"The 23rd Digital Avionics Systems Conference (IEEE Cat.
