Benefits – data qualityDigital data: clearer / more precise than free text enables validation
automatic by the system visually by the operator

Data validationIs it correct, complete, …
safe for intended use?

Using SBVR• SBVR = (OMG) Semantics of Business Vocabulary and Business Rules
– defines the vocabulary and rules for documenting the semantics of business vocabularies, business facts, and business rules.
– http://www.omg.org/spec/SBVR/1.1/PDF
• Example– “The geometry of operational airspace of type CTA, UTA and OCA shall be encoded as an
aggregation of the corresponding operational SECTORS”
– Each Airspace.type equal-to ('CTA','UTA', 'OCA') shall have exactly one AirspaceGeometryComponent.operation equal-to 'BASE' and shall not have AirspaceGeometryComponent.operation equal-to ('INTERS', 'SUBSTR', 'OTHER') and shall have each AirspaceVolume.contributorAirspace.type equal-to 'SECTOR' and each AirspaceVolumeDependency.dependency equal-to 'FULL_GEOMETRY'

Digital NOTAM – specific rules
• “Notes contained in TimeSlice(s) associated with a Digital NOTAM Event shall be limited to the character set indicated in the Digital NOTAM Event Specification, Part 1, section ‘Character Set’”
• Each Note that is-descendant-of FeatureTimeslice that has assigned descendant event:theEvent shall not have assigned translatedNote.note using a different character from {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z', 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9','-','?',':','(',')','.',',',"'",'=','/','+'}.

Digital NOTAM in Europe
• SESAR– Digital NOTAM Prototypes (Thales, Frequentis)– Digital Briefing Prototype (Frequentis)
• Other industry projects– IDS, Comsoft, SnowflakeSoftware, etc.– Likely to see on State going live in the next 12 months!
• OGC OWS test beds– See OWS-10 reports: visualisation, use of WFS, WS-N,
etc.
![Page 18: Delivering Digital NOTAMs Progress of Digital NOTAM Development and Implementation Presented By: Eduard Porosnicu (Eurocontrol) Date: August 25 th, 2014](https://reader037.vdocuments.net/reader037/viewer/2022103122/56649c935503460f9494ebbe/html5/thumbnails/18.jpg)
Challenges
• Baseline data availability– Digital data correctness/completeness
• Re-training of operators– Stop thinking in ‘Q codes’– No longer access to manually modify the text
• Delegation of digitisation to data originators– Availability of tools– Fear of “loosing control”
• Stability of specifications– Early adoption comes with improvement

• Digital NOTAM– the only way forward– has many benefits– it is feasible world-wide
• United States – Europe cooperation– key for the success of the project– FAA – Eurocontrol joint developments under Memorandum of
Cooperation, Action Plan 20
