One of the reasons underlying automation-related problems is the relatively indiscriminate application of automation based on technological availability rather than operator need. This has placed system operators in roles that are poorly suited to human capabilities. A more productive approach to automation and humans would recognize the need to maintain appropriate roles for the human operator, the need to match automation functionality to operator tasks, the need for the human interface to make automation functions highly visible to the operator, and the potential for operator over- and under-reliance on the automation.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126651493","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}

SSTI is a two year to flight program. The science instruments and several of the advanced technology demonstrations each require periods of high bandwidth telemetry. These requirements cannot all be met simultaneously with a conventional fixed telemetry stream, given the relatively low bandwidth of the communication link. A Variable Telemetry Protocol (VTP) and associated flight and ground software have been developed for the SSTI Clark program to handle the temporal variation in telemetry bandwidth during the mission. The VTP protocol is capable of modifying the content and rate of the telemetry stream based on a simple ground command. This paper will discuss the software implemented in the Command and Data Handling subsystem for the collection, storage and flow control of telemetry in a multiprocessor environment. In addition, a relational database management system will be discussed which captures all required telemetry attributes and automatically generates flight code used to setup measurement storage, processing and monitoring functions. This database also contains a built-in communication link simulation to test telemetry configurations against the capability of the communication link and associated contact profile.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123846025","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}

Today's microprocessors have millions of transistors, operate at frequencies greater than 100 MHz, use process technologies with feature sizes less than 0.5 microns, and utilize sophisticated architecture techniques to maximize performance. This paper surveys the current technology trends in microprocessors. Topics include advanced architecture techniques such as superscalar, branch prediction, on-chip cache memory and also process technology improvements. Within advanced architecture and process technology there are several possible improvement techniques. Superscalar and branch prediction work in concert to reduce the time that the processor is waiting. Separating data and instruction cache, along with a larger bus size, can reduce the number of required accesses to slower system memory. Functional redundancy check reduces error rates in multiprocessor systems through redundancy. Finally, the steady improvement in process technology reduces chip size, operating voltage and power while simultaneously increasing the computation rate.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129382718","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}

Together, we are repackaging MasPar's highly successful, commercial, massively parallel processing system to minimize size and maximize survivability in severe environments.

Free Flight is an alternative to the existing outdated approach to Air Traffic Management. It is a system wherein each aircraft is allowed to operate using the flight path, in all four dimensions, that is determined to be best suited by each individual operator or pilot for their aircraft. Free Flight would apply from gate to gate and to all aircraft, from the biggest jumbo jet to the smallest home built, including military aircraft. All users of the airspace system would benefit without regard to the airborne avionics. The installation of a computerized conflict probe alone will support enroute Free Flight to within 50 NM of hub airports, at all altitudes, using current separation standards. This can be accomplished by 1998.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130982348","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}
