Self-adaptive mechanisms are crucial to enable run-time reconfiguration and increase parts reuse in other computer systems and environments. These systems must satisfy functional and nonfunctional requirements. Despite efficient data integration being a common aspiration, the practicality of achieving interoperability remains a challenge for quickly transforming functional processes. For other components work together with the existing ones, and for the new system components development to operate seamlessly with and among other systems, while maintaining proprietary information integrity, the adoption of a common set of \"building codes\" is required. This paper proposes a self-adaptive framework for a real-time system through a scope analysis of stakeholders' requirement. It implements generic behavioral models for Systems Servers and Invokers. Changes on a statechart dimension while adapting a system to the framework lead software engineers to a nearly transparent integration process. Platform dependencies are also captured separately, enabling code-generation subsystem to reuse same components across a wide range of heterogeneous platforms and real-time systems. The framework can lead software components to high degrees of cost-effective reuse and it is tested in a real-time system prototype developed in the Brazilian Aeronautical Institute of Technology (Instituto Tecnologico de Aerondutica -ITA). The proposed framework focused on self-adaptive services components at run-time and on an efficient interoperability approach. At the end, functional requirements and the software architectural structure are enforced such that the end-to-end timing behavior of the resulting system and its specifications can be verified.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126514470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The precision that results from trajectory-based operations will improve the efficiency of traffic flow management (TFM) and air traffic control (ATC) operations, as well as the productivity of TFM and ATC service providers. Performance-based air traffic management (P-ATM) is a set of capabilities, validation activities, and an operational concept for the NAS that promotes and takes advantage of flight deck and ground automation advancements. It is a step toward Next Generation Air Transportation System (NextGen) that has been demonstrated in a simulation environment and shows great promise as a scalable solution that is necessary, desirable, and achievable. A key enhancement in the progression towards NextGen is the transmission of aircraft intent information and its use in both air and ground-based systems to support trajectory-based operations. This paper addresses three areas of research and development to support this enhancement in the context of the P-ATM capabilities. These areas are: (1) Development of avionics interface definitions for the provision of target state intent data. (2) Importance of including planned transitions in the aircraft's airspeed as part of its intent information. (3) Mechanisms for efficiently encoding intent information to support its delivery in the P-ATM timeframe.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130713477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of latency on flight information displays 延迟对飞行信息显示的影响

These new display systems must be able to handle up to sixteen video and graphics sources, including forward-looking infrared (FLIR) and weather information. We designed a pilot-in-the-loop flight simulator study to determine the effects of latency for a head-down Primary Flight Display (PFD) with a large field of view Synthetic Vision surround, a central inset containing sensor imagery (Forward Looking Infrared), and a non latent 2D guidance symbology layer. The investigation was designed in two parts, a breadth study that served as an overall screening for the effectiveness of a relatively large number of variables, and a depth study that explored deeper into effects caused by variables that were deemed significant and important from the breadth study. The results of our study indicate the need to synchronize the latencies of a large field of view attitude indicator and a central inset FLIR overlay. Unsynchronized overlays cause an effect that we refer to as \"swimming\", which is annoying to the pilot, leads to higher workload, and causes distractions that may lead to some amount of flight technical deterioration as demonstrated by our results. Within the limits of the latencies that were administered in this study, we found only a very small effect on actual flight technical performance. Positional accuracy and heading alignment was not strongly affected and generally remained well within limits specified by most practical test standards (PTS). Pilots tended to compensate by operating the flight controls with more gain and with larger amplitudes. This change of the controlling strategy indicates a reduction in aircraft controllability and may not be desirable for prolonged operations.","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115171068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Federated avionics architectures make use of distributed avionics functions that are packaged as self-contained units (LRUs and LRMs). IMA architectures employ a high-integrity, partitioned environment that hosts multiple avionics functions of different criticalities on a shared computing platform. This provides for weight and power savings since computing resources can be used more efficiently. This paper establishes the benefits of transitioning to IMA. To aid in the planning process, the paper also identifies factors to consider before transitioning to IMA. The approach to resource management (computing, communication, and I/O) is identified as the fundamental architectural difference between federated and IMA systems. The paper describes how this difference changes the development process and benefits the systems integrator. This paper also addresses misconceptions about the resource management mechanisms that can occur during a transition to IMA and concludes that resources are not inherently constrained by IMA architectures. Guidance is provided for transitioning to both \"open\" and \"closed\" IMA architectures. Open IMA architectures utilize open interface standards that are available in the public domain. Closed IMA architectures utilize proprietary interfaces that can be customized. The analysis of these avionics architectures is based upon the authors' experience in developing platform computing systems at GE Aviation. GE Aviation has developed open system IMA architectures for commercial aircraft (Boeing 787 Dreamliner), as well as military aircraft (Boeing C-130 combat aircraft, and Boeing KC-767 Tanker).","PeriodicalId":242641,"journal":{"name":"2007 IEEE/AIAA 26th Digital Avionics Systems Conference","volume":"87 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120888051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
