A key TBO-component for LVNL is to achieve more environmentally friendly arrivals by introducing Continuous Descent Approach (CDA) in the Terminal Area (TMA) during daytime along fixed Precision Area Navigation (P-RNAV) routes. Simulations and calculations demonstrated decreased controllers’ workload and reductions in noise nuisance for use of P-RNAV routes and in fuel burn for CDA operations.To realize CDAs flown along P-RNAV routes, more predictable and stable arrival traffic flows are needed. Therefore, more accurate delivery of flights at the Initial Approach Fix (IAF) is required. LVNL is developing a decision support tool (Speed and Route Advisor - SARA) for controllers in the Area Control Centre. Simulations show that the reached accuracy of the target metering time window at the IAF can enable CDA along TMA P-RNAV routes.","PeriodicalId":221205,"journal":{"name":"Air traffic control quarterly","volume":"471 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127521525","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 decision variables in the model are departure delays and predeparture reroutes of aircraft whose trajectories are predicted to cross weather-impacted regions of the National Airspace System. The model assigns delays to a set of flights while ensuring their trajectories are free of any conflicts with weather. In a deterministic setting, there is no airborne holding due to unexpected weather incursion in a flight’s path. The model is applied to solve a large-scale traffic flow management problem with realistic weather data and flight schedules. Experimental results indicate that allowing rerouting can reduce departure delays by nearly 57%, but it is associated with an increase in total airborne time due to longer routes flown by aircraft. The computation times to solve this problem were significantly lower than those reported in the earlier studies.","PeriodicalId":221205,"journal":{"name":"Air traffic control quarterly","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123651783","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 current practice in use by FAA safety analysts of using three categories is simple, but precludes making comparisons from data aggregated across the full range of separations. The proposed model rectifies this shortcoming by providing an approach to rating severity based on a relative collision probability estimate for an event that is replayed with quantitative separation variability based on published estimates. The model incorporates: (1) consideration of event reenactment of given horizontal and vertical separation with specified variability in each dimension, (2) probability density of co-location of the two aircraft to account for the overlap in aircraft variability for the event reenactment (formally the convolution or aggregation of co-location densities), and (3) size of each aircraft involved in horizonta...","PeriodicalId":221205,"journal":{"name":"Air traffic control quarterly","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125888300","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}

Previous research has pointed to a number of operational benefits of RA downlink display, such as an improved controller situational awareness and a smaller likelihood of contradictory clearances to aircraft involved in an RA event. However, these benefits of RA downlink display only pertain to RAs that, if complied with, cause a deviation from the Air Traffic Control (ATC) clearance. In order to investigate the frequency and type of RAs in core European airspace, EUROCONTROL initiated the PASS monitoring study. Within this study, RA downlink data from six Mode-S radars covering a large part of the core European airspace were collected from September 2007 to March 2008.

The authors explain the rationale for development of such a tool: the authors suggest the introduction of a wake-vortex advisory system could save some $15 million annually in direct operating costs at congested airports with closely-spaced parallel runway configuration. The authors provide a system overview; a review of related wake vortex advisory systems; the required topology; and the necessary meteorological data for temporal and spatial coverage. An important feature of the WSVBS is the use of measured and predicted meteorological quantities as input to wake vortex prediction. Also included is a section on systems integration that describes how components are combined for prediction of adapted aircraft separations.","PeriodicalId":221205,"journal":{"name":"Air traffic control quarterly","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114677652","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}
