  1. Digital Airport Surface NOTAMs

  2. Introduction • What are NOTAMs? • Notices to Airmen (NOTAM) are used to alert pilots about temporary changes affecting the National Airspace System • Problem? • Manual generation – Free form text • Difficult to Read • Inconsistency and Lack of Standardization • Unable to fully computerize • Delivery challenges • SAFETY CRISIS !!

  3. Automation – Digitally Encode Application for creating NOTAMs Data Model – provides structure Graphical output Machine readable standards based message Digital Airport Surface NOTAMs First step Small set of Airports Subset of Features Demonstrate customer value Solution

  4. Goals of the Project • Digitally encode and transmit airport surface NOTAMs • Integrate static and dynamic information • Fully data modeled • Fully geo-referenced • Develop digital NOTAM data views • Traditional formats (US and ICAO) • Plain Language • AIXM • Identify and address technology and policy risks • Concept of operations • Digital distribution and management • Information for navigational use

  5. Concept of Operations DATALINK AIM EVENTNOTAM trigger (e.g., Runway damage) AUTHORAirport Authority PUBLISH Web Service,Product Specs GLOBAL AIM NET Aeronautical Information Transactions

  6. Concept of Operations Prototype Triggering event at the Airport (e.g., Runway damage) <AIXM> Text Airport Authority CREATEDigital NOTAM VALIDATE Authorization, Business Rules PUBLISH Web Service,Product Specs Map Demonstrate completeness of data modelFamiliarization and translation USNS ENCODEDigital NOTAM

  7. AIXM as the Foundation • AIXM 5.0 Based Data Model • Comprehensive data model – Globally applicable • Temporality • Data content separate from product specification • To ease mapping message elements to data • NOTAM Message Service– AIXM • Worldwide interoperability • Integrate into loosely coupled systems • Instantly available upon activation

  13. What’s Next • Take it to the Next Level • Create NOTAMs • End-to-End Workflow • Interface with US NOTAM System • Multiple output formats: Plain Language, FAA, ICAO • Improved mapping

  14. Concept of Operations Candidate Transition Plan Triggering event at the Airport (e.g., Runway damage) <AIXM> Text Airport Authority CREATEDigital NOTAM PUBLISH Web Service,Product Specs Map VALIDATE Authorization, Business Rules US NOTAM Office validates and numbers NOTAMsMaintains legacy interfaces and productsReduces USNOF workload by standardizing NOTAM entry Legacy productsLegacy interfaces USNS

  15. Conclusion • Digital Airport Surface NOTAMs towards building a fully Digital NOTAM solution • Identify technology challenges • Develop a concept of operations • Demonstrate value
