An enhancement current to the AAS will be the automation capabilities collectively known as automated en route ATC (AERA). AERA is being designed with several goals in mind: to enhance safety, increase user benefits, increase controller productivity, and increase system capacity. To meet these goals, many AERA capabilities are being designed, one of which is the increased use of data link. AERA data link capabilities are described, showing how AERA's use of data link will provide user capabilities to accommodate requests better than has been possible in the past, while reducing the amount of verbal communication required with the aircrew and reducing communication errors.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"188 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":"133261835","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}

This optical data link consists of a transmitter and a receiver, each self-contained in a compact package which may be used on both sides of standard electronic module circuit boards. Packages are hermetically enclosed and contain no organic materials. The transmitter and receiver operate at an optical wavelength of 1.3 mu m. Each uses a pigtail which may be selected to interface with either 62.5/125 or 100/140- mu m multimode optical fiber. The electrical input and output signals are 100K ECL (emitter coupled logic) compatible. From -55 degrees C to +125 degrees C this link typically allows for approximately 20 dB of optical loss in a system.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"14 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":"123237916","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}

General integration trends in avionics systems architecture are examined with reference to the Boeing Company's fleet of aircraft. It is shown that for two of the key measures of system development difficulty, system size and complexity, the difficulty (time and labor) is increasing with no change currently in sight. This type of growth has a large impact on the way avionics systems development is engineered and managed. It is suggested that new engineering disciplines, computing tools, and training are needed to manage the design of these systems.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"51 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":"122474216","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 utilizes explicit software contributing factors for avionics architecture design and assessment. The methodology is based on a four-step process: definition of candidate data management systems (DMSs), definition of candidate avionics architectures, architecture evaluation from software and other subsystem viewpoints, and architecture evaluation from total avionics system viewpoint. User-defined software contributing factors, along with those for other subsystems, are used to define and evaluate the architectures objectively. The methodology was applied to a generic avionics system, resulting in a set of candidate avionics architectures and associated evaluation data.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"113 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":"117261018","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}

Life cycle cost (LCC) studies performed for the MASA program showed significant savings when a modular architecture was used to integrate at least two or three avionics functions. These studies also showed no significant LCC penalty for the modular implementation of a single function. Other advantages not quantified in the LCC analysis include increased competition, reduced time lag for technology insertion, and more effective implementation of integrated systems and fault tolerance. Some of the more interesting results were for fault-tolerant modular systems which could provide a high probability of full operational capability for a 30-day combat surge with no line maintenance.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"23 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":"116842875","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}

Emphasis is placed on two architectures of an optical flight control system designed for use in a redundant flight control system. Option one is a passive system which requires no power transmission lines to the optical components at the actuator. All of the optical signals are returned to the optical interface electronics in the flight control computer and are processed in the box. Option two is an active system in which optical data are sent from the flight control computer to the actuator along an optical bus, usually a MIL-STD-1773 1-to-2 Mb bus, and then back to the flight control computer along the same bus. In option two, the closed-loop control around the actuator is done with a microprocessor in the actuator control electronics module (ACE), which is an electronic box placed on the actuator and powdered by a 28-V line from the flight control computer power supply. This concept is considered active because 28-V power is transmitted outside the flight control computer. It is shown how active systems could be used to provide feedback to the flight control processor and how each system interfaces to the flight control computer. The merits and shortcomings of each system are discussed in detail.<<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":"128282827","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}
