Aeronautical information criticality Data quality?

eAIP, iPIB Applications Aeronautical Information Management Data management NOTAM AIP, charts, etc. State 2 Data management State 1 NOTAM AIP, charts, etc. Surface mail DATA Regional database State 3 AIP, charts, etc. NOTAM ARO NOTAM AIP AFTN (low bandwidth) bulk data upload Briefing data update services Data Service Provider Standards AIXM

Role of models in AIM AIP Classical AIS - publish documents Document content and format is described by: - ICAO Annex 15, Appendix 1 – AIP Content - ICAO Annex 15, Appendix 6 – NOTAM format - ICAO Annex 4, Aeronautical Charts - FAA forms SUP, NOTAM, AIC AIM System - manage data - publish traditional and new products - accurate and fast exchange Data managed in the system is described by models: - ARINC Aeronautical Information Exchange Model (AIXM) - Electronic AIP (eAIP) Specification - Airport Mapping Database (AMDB) - Terrain and Obstacle Database - New products…

Streamline data management and product maintenance –Model aeronautical information as a whole –Create AIS products from a single data source –Ability to integrate workflow and configuration management Streamline data management and product maintenance –Model aeronautical information as a whole –Create AIS products from a single data source –Ability to integrate workflow and configuration management Data management AIS Office Product Creation Engines Products Purpose of AIM Improve internal processes

AIP NOTAM AIP NOTAM “data layer” Purpose of AIM Improve external processes

Role of data models –To represent real world concepts as a theoretical construct which can be represented and understood by automated systems –To standardise the conceptual understanding of aeronautical data by all actors - “speak the same language" –To provide a basis for logical data structures used during the software implementation –To provide basis for formal ‘contracts’ between interoperable systems – example: “use the same format" Role of data models –To represent real world concepts as a theoretical construct which can be represented and understood by automated systems –To standardise the conceptual understanding of aeronautical data by all actors - “speak the same language" –To provide a basis for logical data structures used during the software implementation –To provide basis for formal ‘contracts’ between interoperable systems – example: “use the same format" Data modeling is important
