More complex multi-segmented instances where the waypoints defining the reference route and the RPI route are not collinear will also be analyzed and compared.

In order to maintain some form of redundancy, a networked, system-wide back-up and validation approach is required. During the transition to end-state surveillance architectures, there are likely be a mixture of various types of surveillance sources including primary surveillance radar, secondary surveillance radar, multilateration, and ADS-B. This paper describes an integrated approach to the surveillance architecture and one means for facilitating the application of multiple surveillance sources. Surveillance sensor performance is based on the categories defined in ADS-B standards. The relevant parameters are navigation accuracy category (NAC), navigation integrity category (NIC), and surveillance integrity level (SIL). These standards have been adapted to create a generic surveillance performance categorization method. This method would enable air traffic service providers to develop criteria for combining information from multiple surveillance sensors. The categorization also enables a method for defining the associated aircraft separation requirements","PeriodicalId":443824,"journal":{"name":"2006 ieee/aiaa 25TH Digital Avionics Systems Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124613640","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 OTDR launches a very narrow pulse into the fiber and then records the response of the cable/connector assembly to this pulse. Both reflections and absorption can be observed in the cable, providing the troubleshooter with the information needed to diagnose cable problems. Boeing Phantom Works has developed an OTDR function that eliminates all of these problems. Because it can operate with very low-level optical power, the OTDR function can use the same laser and detector used for communications. The recurring cost of the added hardware is expected to be relatively low and will fit into the standard fiber optic transceiver packages currently in use in military and commercial aerospace applications. Because the OTDR function is built in to the fiber optic transceivers, no connectors need to be demated. As a result of this new network diagnostic technology, a technician will be able to locate a fault down to the box or cable in a matter of minutes and, in the case of a cable harness fault, will be able to locate to within inches the cable fault","PeriodicalId":443824,"journal":{"name":"2006 ieee/aiaa 25TH Digital Avionics Systems Conference","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122764818","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}

Presented is a methodology that can be used to define and forecast the range of user responses to new technologies that require aircraft equipage. The responses can be linked to potential FAA actions and policies regarding the technology, which could include: relying solely on voluntary user equipage, supplying subsidies for all or a portion of the avionics cost, and creating rulemaking to require certain capabilities in specific airspace. This user response forecast, when combined with model- or type-specific aircraft knowledge, provides an estimate of the future mix of aircraft capabilities, and can be utilized to determine overall fleet upgrade costs for unequipped aircraft.
