The performances of these systems are often evaluated based on their compliance with the guidance document of performance specifications and test procedures for civil aviation equipment. One of the key performance parameters is Probability of Detection (PD). For a stable surveillance system, the value of PD tends to be fixed and the confidence level of the evaluation test rises as the sample size increases. However, in practice, tradeoffs have to be made between sampling time and precision of estimation. This paper discusses the impact of influence factors on the PD estimation in surveillance systems. The theoretical relations with the significance level and the deviation of measured PD from the required PD are presented. Recommended sample size tables are presented in the discussion for MLAT, ADS-B, and SSR respectively for reference.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126376095","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}

These tools simulate the operation of up to 60,000 flights per day in various combinations of demand (i.e. flights) and capacity (i.e. airport and airspace capacity). The main input to the simulation is a schedule of flights (not a schedule of passenger itineraries). As a result, estimates of passenger delays assume all passengers are on direct itineraries only, and the impact of cancelled flights, missed connection, and airline network effects are not considered. This paper describes the results of an aggregate model of the operation of a hub-and-spoke network that takes into account passenger itineraries (i.e. direct and connecting) and a ll forms of itinerary disruptions (i.e. delayed flights, cancelled flights and missed connections). This model shows that the reduction in lost economic productivity generated from NAS-wide simulations is under-reported, as passenger trip delays due to delayed flights only account for approximately 40% of the total passenger trip delays. Furthermore, the model identifies the significant roles played by factors other than flight performance, such as airline itinerary structure, airline fleet mix (i.e. aircraft size), load factors and airline hub banking structure, on total passenger trip delay. For example, a 7–10% increase in load-factor can nullify the reduction in total passenger trip delay gained by a 5% improvement in on-time performance achieved by NextGen. The implications of these results on NextGen benefits assessments through NAS-wide simulation are discussed.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133190117","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 description covers the architecture of the communication products like CMU (Communication Management Unit), in connection with associated redundancy design requirements; methods for data exchange / synchronization between redundant computers, technique used to identify a failed computer / CMU, notify this failure on-board to the crew, changing the mastership of the computer, methods for recovery of the failed computer. In addition this describes about the number of redundant computers that are required to fulfill the criticality / safety levels of the aircraft operations; how dissimilar architecture concepts could be leveraged to provide protection against common mode failure triggers. Non-failure situations like performance degradation of a computer (operating closer to failure ranges), degradation of redundancy management / synchronization capabilities of a computer should also be considered as factors necessitating the change of mastership. The debugging / built-in testability features would also depend up on the redundancy management architecture used to build the final product.

While developing requirements from system requirements to high level and low level requirements, the requirements would be completely analyzed for safety perspective. The advantage of this proposal is that the functional modules interface requirements are analyzed and captured from safety perspective. Reuse of the product extracts specific safety related requirements at each functional level as the requirements are developed at each interface modules. This leads to extensive verification of interface requirements along with system requirements which would leads to a safer product.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116856498","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 selection process needs to be designed and implemented by sampling historical operational data for each fiscal quarter and choosing representative days that best reflect seasonality in terms of a given set of performance metrics. We propose an optimization based solution method for the sample day selection problem, which is formulated as a Mixed Integer Program (MIP). The objective of the MIP is to minimize the weighted difference between the true population and the sample to be selected in terms of the defined metrics subject to a set of constraints including the sample size limit, coverage requirements and other desired properties. An efficient solution algorithm has been implemented using the CPLEX MIP solver. Experiments have been conducted with a wide range of flight data from the recent years. The results from the MIP method provided robust solutions for the sample day selection problem. It is also shown that the method is quite flexible to incorporate additional constraints based on expert knowledge.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131561652","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}

Although it is envisioned to accommodate broadband IP and other communication networks in the future, the initial version of this protocol only supports existing ACARS networks. One of the immediate intents of MIAM is to support the transfer of messages much larger than possible in the ACARS subnetworks through message segmentation and reassembly features. In an attempt to reduce the impact of MIAM transfers on the ACARS networks, the protocol includes data compression, segment temporization, and flow regulation controls. This paper begins with a discussion of the MIAM protocol. The protocol is analyzed and tested through detailed simulations of the ACARS VDL Mode 2 subnetwork with various traffic profiles and protocol parameters. As the inclusion of large messages may add significant load, the study investigates the flow regulation features of MIAM and its effects on the underlying ACARS network, looking for adverse impacts on other ACARS traffic. The findings of this study are presented and discussed in conclusion.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131902069","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 wireless data service can augment the projected Datacomm services to aircraft or vehicles by providing connectivity to A ir Traffic Control, Airline Operations Services and Airport Communications Services. Results from the joint Future Communications Study conducted by U.S. Federal Aviation Administration (FAA) and EUROCONTROL recommended the use of existing wireless communications technology based on the commercially available 802.16 2009 standard as the solution to support the future aviation requirements on the airport surface. This system, referred to as the Aeronautical Mobile Airport Communications System (AeroMACS) would operate in available protected aviation mobile communications spectrum from 5091MHz to 5150MHz. In addition to alleviating an already congested VHF communications band, the AeroMACS system would also provide a capability to support data intensive applications projected under the FAA's future Next Generation (NextGen) and the Single European Skies Aviation Research (SESAR) Programs. RTCA Special Committee 223 (SC-223) was organized to develop an Aviation Specific System Profile that could be used to guide the design and implementation of equipment and systems used in a broadband airport surface wireless network in the United States. RTCA SC-223 is coordinating with the EUROCAE Working Group 82 and SESAR in the development of the AeroMACS profile. Additionally, since the WiMAX Forum owns and holds the copyright for the 802.16e standard, the RTCA SC-223 profile working group has established a working relationship with the WiMAX Technical Working Group (TWG) to participate in the generation of the AeroMACS profile, and issue any needed change requests to the Mobile WiMAX Release 1 System Profile (DRAFT-T23–001-R010v09-B_MSP) document.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130103872","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 order to ensure the proper exchange of data to support these systems during development, the FAA needs to develop interface requirements. Defining the interfaces necessary for managing airport surface operations, in particular departure management, between the Air Traffic Control Tower system, the Tower Flight Data Manager (TFDM), and TFM Systems first necessitated an evaluation of an initial set of Surface DST capabilities (those identified for initial implementation, referred to as the initial DSTs). A determination of which capabilities should be allocated to systems associated with tower and TFM is also necessary.
