The purpose of the analysis is to define a systematic process by which the various constraints of crew deconditioning, crew training, and operational environment could be balanced in designing the crew's response to automation failures. The results of the analysis include an automation taxonomy in which crew involvement in a given situation is bounded at one end by mission requirements and level of automation failure and at the other by crew capabilities, and a list of crew functions at each level of potential crew involvement.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134037820","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 areas of application of artificial neural networks to avionics dealt with are: target selection, attack planning/steering, and track-before-detect. The target selection is approached by the application of a feedforward, backpropagation network. The attach planning/steering is approached by a novel type of parallel processing neural network. The track-before-detect is solved via a feedforward backpropagation network. The feedforward backpropagation algorithms can be implemented on fast systolic-array-type neural chips. A special, fast path generation chip can be developed. Consequently, a low-cost, high-speed, compact solution to a number of avionics functions is available through neural networks.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130380211","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}

It is indicated that fault-tolerant guidance and control systems can be employed to meet the goals of the advanced launch system. Proven redundancy management techniques are proposed for implementation in such guidance systems. The methods discussed provide a high probability of failure detection while maintaining a low probability for false alarms. A hardware architecture that stresses robustness, simplicity, and ease of verification is advocated. The channelized repartition of instruments and electronics can be modified to support different requirements and applications. The issue of simultaneous or dormant failures is addressed. The fault-tolerant architecture and implementation discussed is considered to provide excellent reliability and probability of mission success, while maintaining very reasonable costs.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123268420","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 results of work performed by the Wright Research and Development Center (WRDC) for the embedded computer resource support improvement program are detailed. The findings of the modular embedded computer software effort conducted for WRDC's software concepts group are described. A software development paradigm, based on automation, that addresses the knowledge gap faced by software support personnel has been identified. The underlying premise of this model is that software and its delivered documentation need to be united into an integrated system development product (ISDP), where relevant support information is organized into a structured hypermedia knowledge base. The key to this software design knowledge program is that the ISDP be integrated by means of a computerized development memory, which contains all of the motivation and rationale that influenced the development of the software. The development memory and its support software would serve a large-scale software development effort in the same way as human memory serves a single developer.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124692501","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}

A workstation-based, rapid-prototyping environment, was developed to support iterative definition of ELS concepts, especially viable crew interface techniques and display screen formats. The results of Phase 1 evaluation are presented, to assess the effectiveness of the crew interface design. The only features of the user interface to receive marginal ratings were response times for printing, text pages and charts. All other features were deemed to be acceptable or excellent.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115234471","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}

Differing logic families have differing input and output device impedances. Consequently, these logic types can have profoundly different responses over any given bandwidth. Understanding the effect that these impedances can have on the upset levels in circuit boards employing these logic families can aid the designer early in the design cycle to minimize random and potentially dangerous circuit responses. Analytical models describing the effects of incident EM fields on cables over ground planes have been developed. The development grew out of a need to understand HIRF-type phenomena inside the fuselage of aircraft. High-incidence EM fields can generate significant induced fields on the aircraft cables. These fields can in turn develop large voltages at the inputs to avionics circuits. These levels can and do approach the upset thresholds. Knowing the frequency dependency of the impedances attached to the ends of aircraft cabling is of utmost importance.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116733113","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}

Key features of the architecture which provide fault tolerance include redundancy management, processor synchronization, and multiple voting planes. Modular building blocks for constructing such a distributed vehicle management data processing system, based on contemporary common module designs, are described along with resulting performance attributes. The application of software support environments, including Ada, is presented. An assessment of resulting reliability and safety is also presented. It is concluded that the use of standardized building blocks provides a flexible, cost-effective method for designing, assembling, validating, producing, and operating a variety of application-specific implementations. The same flexible features allow for future growth to include additional system capabilities with a minimum impact on already fielded configurations.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130790336","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}

Advantages that a data link provides are increased situational awareness, cooperative missile launches, flexible formation flying, and potentially cooperative application of electronic countermeasures. The data link requirements to support such tactical operations are presented, and are shown to be critically dependent on the ability to exchange target tracking data between aircraft. Most advanced fighter studies and projects include some concept of cooperative functions using an intraflight data link. This link is assumed to be covert and unjammable. A number of cooperative concepts and their data transfer requirements are examined. These functions are organized into three categories: situation awareness, offensive functions, and defensive functions.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132945984","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}
