This new concept represents a paradigm shift from “creating ensembles of weather information” (e.g., maps of predicted weather hazard intensity) to “developing ensembles of aviation userrelevant information” (i.e., maps of potential throughput as measured by the available flow capacity ratio), which entails a translation of weather forecasts into predictions of reduced airspace capacity. The proof-of-concept is exemplified by focusing on convective storms; however, the advocated approach may be applicable to other aviation hazards, like turbulence, icing, or ceiling and visibility as well. Although the concept is most pertinent to strategic en route traffic flow management, it could be extended to terminal area applications, such as predicting major wind shifts on runways, the onset of precipitation, or a transition from rain to snow. A probabilistic approach is most appropriate for strategic planning horizons, for which deterministic weather forecast are significantly less accurate and an ensemble of forecasts may provide better guidance about the spread of possible future weather scenarios.","PeriodicalId":313168,"journal":{"name":"2009 IEEE/AIAA 28th Digital Avionics Systems Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133566120","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}

Subjects were asked to fly 20 approaches to the Apollo 15 lunar landing site with four different display concepts - Baseline (symbology only with no terrain imagery), EV only (terrain imagery from forward looking infrared, or FLIR, and light detection and ranging, or LIDAR, sensors), SV only (terrain imagery from onboard database), and fused EV and SV concepts. As expected, manual landing performance was excellent (within a meter of landing site center) and not affected by the inclusion of EV or SV terrain imagery on the Lunar Lander flight displays. Subjective ratings revealed significant situation awareness improvements with the concepts employing EV and/or SV terrain imagery compared to the baseline condition that had no terrain imagery. In addition, display concepts employing EV imagery (compared to the SV and baseline concepts which had none) were significantly better for pilot detection of intentional but unannounced navigation failures since this imagery provided an intuitive and obvious visual methodology to monitor the validity of the navigation solution.","PeriodicalId":313168,"journal":{"name":"2009 IEEE/AIAA 28th Digital Avionics Systems Conference","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134526268","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 trials, which took place in low and peak traffic, highlighted the potential benefits that can be gained by assuming that aircraft can meet a controlled time of arrival (CTA) with high accuracy and by assigning that time up to 45 minutes prior to a metering point for the Stockholm Terminal Maneuvering Area. Boeing 737NG aircraft, equipped with the most advanced Flight Management Systems, could meet their assigned time with 30 second accuracy in 88% of the trials. Pilots of MD-80 aircraft, which do not have an FMS function to aid pilots in meeting CTAs, met their assigned time with 30 second accuracy in 73% of trials. An analysis of these flight trials and the potential impact of their results is carried out. A number of CTA based applications which take advantage of the aircraft's ability to meet an assigned time are proposed and evaluated. One of these applications is “delay en-route”, or having aircraft slow down to meet a CTA rather than performing orbital holding at a low altitude. Another application explored was “delay on ground”, where aircraft departing from a nearby airport were assigned a CTA prior to takeoff and could avoid eventual holdings by delaying takeoff. This paper will also present recommendations as to how CTA operations can be further developed and introduced into operations.","PeriodicalId":313168,"journal":{"name":"2009 IEEE/AIAA 28th Digital Avionics Systems Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133445141","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}

In contrast, the author's research has concentrated on the development of methods that can significantly enhance the performance of legacy systems while requiring few or no hardware modifications. If hardware replacement is allowed, these methods can be leveraged to further improve the upgraded systems. The methods can be characterized either as algorithmic or architectural methods. Algorithmic methods include techniques such as new data compression routines. A previous paper by the author and a fellow researcher has presented data compression routines that are suitable for implementation on legacy MIL-STD-1553 data buses. As expected, these routines where shown to increase the communication throughput. What may be less obvious is that they also increased the time available to perform computation. Architectural techniques include repartitioning of software functions and/or communications to free system resources. This paper presents these and other methods for increasing the performance of legacy avionics systems. The same techniques can also be applied to improve the design of new systems.","PeriodicalId":313168,"journal":{"name":"2009 IEEE/AIAA 28th Digital Avionics Systems Conference","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131110472","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}
