Advancing Digital NOTAM Implementation: Evolution and Future Trends
The evolution of digital NOTAM implementation from its establishment in 1993 to the current focus on structured data sets for accurate and efficient updates in the aeronautical environment. The transition from text-based NOTAM to digital formats addresses the need for timely and reliable aeronautical information for aviation personnel and automated systems. The presentation highlights the advancements made by Estonian Air Navigation Services and the shift towards harmonized encoding using AIXM data sets. The emphasis is on improving the maintenance and integrity of aeronautical data through digital means.

Advancing Digital NOTAM implementation Olga Mashinskaja AIM expert, Estonian Air Navigation Services Global AIM Santo Domingo 2018 Page 1
Introduction 1993 - Estonian NOTAM Office was established as a part of Integrated Briefing Office of Estonian AIS it is a part of Estonian Air Navigation Services. 1993-2000 A teletypewriter was used for NOTAM distribution 2000 - start of the first NOTAM Office system 2009 Estonian AIS started a Project with Frequentis Comsoft to supply advanced AIM system. The heart of the system is based on CADAS-AIMDB Aeronautical Database fully implementing AIXM 5 standard 2012 - a new system for IBOF including NOTAM Office based on Frequentis Comsoft CADAS product suite 2012 - migration to EAD as Data Provider (NOTAM). 2018 ADQ compliant Work Flow Management system implementation project with Frequentis Comsoft, facilitating NOTAM proposal submission, control, management Global AIM Santo Domingo 2018 Page 2
Need for digital NOTAM Last minute aeronautical information update means NOTAM ICAO definition of NOTAM: A notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations ICAO AIS to AIM Roadmap P-21 Digital NOTAM The digital NOTAM will be defined as a data set that contains information included in a NOTAM in a structured format that can be fully interpreted by a computer system for accurate and reliable updates of the aeronautical environment representation both for automated information equipment and for aviation personnel Instead of creating and maintaining individual text NOTAM with complex release processes, the focus is on the maintenance and integrity of the aeronautical data Global AIM Santo Domingo 2018 Page 3
Need for digital NOTAM The provision of aeronautical information today is mainly focused on the requirements of pre-flight briefing. The provision of aeronautical information tomorrow will address the requirements of all components of the ATM system for all phases of flight. Amdt 40 to Annex15 Data set updates When temporary changes of short duration are made available as digital data (Digital NOTAM), they should use the same aeronautical information model as the complete data set. Digital NOTAM Event Specification Increment 1 The Digital NOTAM Event Specification defines the rules for harmonised encoding as AIXM data sets (version 5.1 or later).

Advancing digital NOTAM implementation In 2017 dNOTAM project was started with Frequentis Comsoft. A NOTAM event commonly used by EANS was selected as proof of concept. Q-code DNOTAM scenario RTCA SAA.ACT / SAA.NEW RDCA SAA.ACT / SAA.NEW Further dNOTAM event configurations in preparation. Q-code DNOTAM scenario OBCE OBS.NEW Global AIM Santo Domingo 2018 Page 5

Impact and challenges STAFF COMPETENCIES Training for NOF staff Basic understanding of AIXM and temporality model, Data base Cooperation and training for Data Originators Transition period while all Data Originators are trained NOF workload increases for the transition period Need for Guidance Materials-> different from OPADD, support from Eurocontrol -> lessons learnt feedback-> further cooperation with Eurocontrol Global AIM Santo Domingo 2018 Page 8
