6 The support of analysis tools to flight inspection activities 6 of 30IFIS 2008, OKC Industry/Criteria Requirement Today’s safe Nav procedures rely upon their reference to fixed ground Navaids –This cannot be assumed in future applications Recent RNAV safety cases highlighted risks and hazards associated with poor data quality Today’s data integrity performance is far from that specified by ICAO. –ICAO requirements not met –No differences filed. Area Navigation and the potential to apply GNSS together depend ENTIRELY upon data quality.

7 The support of analysis tools to flight inspection activities 7 of 30IFIS 2008, OKC Challenges Interoperability and collaboration is a key to the future ANS ORG Is reliant on –with data of the required content, quality & timeliness –The right digital info, right place, right time AIS is introducing ISO9001-2000, but for most it is process only What is required is the fixing of the process of “origination to publication”, The co-operation of all actors in the data processing chain is fundamental and IDS actually have a proven solution to this requirement

8 The support of analysis tools to flight inspection activities 8 of 30IFIS 2008, OKC RNAV REQUIREMENTS ICAO state in the “Flight procedure design Manual” (released in Q3 2008) that the procedure design process consists of different steps: –Requirements and data collection –Design and first ICAO rules checks –Pre-Validation –Flight check –Publication Eurocontrol stated in the “Guidance Material for the Validation of RNAV Procedures” the main steps to be performed in validating RNAV procedures

12 The support of analysis tools to flight inspection activities 12 of 30IFIS 2008, OKC New design challenges from RNAV navigation GNSS related topics ( from ICAO, 2007, Manual on Testing Radionavigation Aids doc. 8071, volume II, Testing of Satellite-based Radionavigation Systems, chapter 1 ): GNSS analysis geodetic survey GNSS monitoring Record keeping availability of prediction SW GPS selective availability

13 The support of analysis tools to flight inspection activities 13 of 30IFIS 2008, OKC New design challenges from RNAV navigation PANS-OPS DME/DME related topics ( from ICAO, PANS OPS-Doc 8168, “Procedures for Air Navigation Services - Aircraft Operations”, Volume II Construction of Visual and Instrument Flight Procedures, vol. 2, part III, sec. I, ch. 3 ): it’s “not possible to know which DME facilities the airborne system will use for a position update, a check should be made to ensure the appropriate DME coverage is available throughout the proposed route …”. N=5 N DMEcouples =10

14 The support of analysis tools to flight inspection activities 14 of 30IFIS 2008, OKC DME/DME related topics ( from ICAO, NAVIGATION INFRASTRUCTURE ASSESSMENT IN SUPPORT OF PBN ): “Appropriate tools should be used to assess navigation infrastructure. While the assessment could be conducted using manual analysis and flight inspection, the use of a software tool is recommended in order to make the assessment more efficient. The software tool should be tailored to allow evaluating the infrastructure in light of the requirements imposed by a specific navigation specification, such as RNAV-1. In general, RNAV assessment tools should include a 3D terrain model with sufficient resolution and accuracy to allow predicting the line of sight visibility of navaids along a procedure service volume, including an analysis of their respective subtended angles and a variety of other geometric constraints.” New design challenges from RNAV navigation – PBN -

15 The support of analysis tools to flight inspection activities 15 of 30IFIS 2008, OKC Procedure validation related topics: ICAO, JAA, and Eurocontrol recognize that the Flyability check is part of the quality process related to an IFP design and publication: Aircraft maneuvering in context of safe operating practices for the category of aircraft Cockpit workload Charting aspects Navigation database aspects New design challenges from RNAV navigation (cont.)

16 The support of analysis tools to flight inspection activities 16 of 30IFIS 2008, OKC Data integrity related topics: ICAO in Annex 15 requires the “Contracting States shall ensure that integrity of aeronautical data is maintained throughout the data process from survey/origin to the distribution to the next intended user. Aeronautical data integrity requirements shall be based upon the potential risk resulting from the corruption of data and upon the use to which the data item is put” The following classification and data integrity levels apply: routine: 1x10-3 essential: 1x10-5 critical: 1x10-8 New design challenges from RNAV navigation – Annex 15

17 The support of analysis tools to flight inspection activities 17 of 30IFIS 2008, OKC Instrument Flight Inspection data management related topics: ( from FAA Order 8240.52 “Aeronautical Data Management” ): the data must accurately reflect the references to be used in the performance of inspecting the systems supporting the National Airspace System (NAS). These data will be the references for certifying the quality of signal-in- space, and the instrument flight procedures New design challenges from RNAV navigation (FAA.52)

18 The support of analysis tools to flight inspection activities 18 of 30IFIS 2008, OKC The IDS approach to the problem IDS has been involved by many years in the provision of system and services with qualified personnel IDS relies on advanced graphics and databases, integrating multiple data sources such as maps, photos, property records, survey and engineering data, inspections reports, traffic safety prescriptions, congestion statistics, documents, aeronautical charts. IDS solutions help the air transport industry to manage strategically and efficiently this information.

40 The support of analysis tools to flight inspection activities 40 of 30IFIS 2008, OKC Conclusions and Recommendations The increasing use of RNAV routes and approaches/departures increase the challenges of flight inspection teams and cost connected activities The international rules from ICAO, Eurocontrol, JAA and FAA are asking for increased level of integrity in aeronautical data due to the fact that aircraft flying strongly rely in the data loaded in the navigation DataBase. This paper has given a short overview of those requirements and has given some snapshots of the solution developed by IDS to meet the though requirements which are asked from the regulators to the air navigation service providers.
