E N D
xNOTAM Trial • Limited set of features: • Airspace, AirspaceUsage; • RouteSegment, RoutePortionUsage, Significant Points (Navaid and Designated Points); • Aerodrome, Aerodrome Surfaces Usage, Runway, RunwayDirection, Taxiway; • Obstacles; • Notes • Reversed Workflow • NOTAM -> digital NOTAM • In future: digital NOTAM -> NOTAM…
Overall • Objectives achieved: • Validate AIXM 5 • encoding the information contained in NOTAM messages • temporality concept • Improvements of the model -> implemented in AIXM 5.1 • Provide a proof of concept for a “digital NOTAM encoding application” • not intended for operational use or for production!!! • we need a much user-friendly and faster HMI for an operational system! • Provide a significant amount of test xNOTAM data • to system developers
Lessons learned • Some key features (airspace, airport usage, obstacle, etc.) account for 50-70% of the NOTAM • End users have priorities for what NOTAM should become digital first • Initial input from LH Systems, SAS, KLM, Eurocopter, etc. • Focus Group task Incremental implementation ! Candidates for increment 1 - Airspace activation / reservations - Route closures - Navaid events - Airport / Runway closures - Obstacles - SNOWTAM - all other NOTAM as text “Note” on the feature !
Lessons Learned • Data provider application shall help the operator to validate the data (HMI-1) • Was all expected data provided? • Does data comply with all business rules? • Is data plausible? • If possible, visualise the data in the context of the static data • Example – closed twy on airport layout • Example – obstacles on airport/airspace background • Example – active airspace on route/airspace background
Lessons Learned • Data provider application shall minimise the data input effort (HMI-2) • Shall have a consistent (unique?) workflow • Avoid re-typing data that is already available • If available, partial AIXM format received from external source (“digital NOTAM proposal”) • At least cut/paste from another application, eventually in human-readable form • Example: airspace coordinates input as (“452434N 0333422E, 452532N 0333401E, 451434N 0333422E”) instead of individual input of each position • Example: “MON-FRI, 09:00-17:00”, “SUN, SAT, HOL”, etc. instead of complex timesheet input form
Lessons Learned • Data provider application shall minimise the data input effort (cont.) • Wherever appropriate, graphical input • Example: twy / twy portion closure • Example: work in progress area
Lessons Learned • ICAO NOTAM Text to be produced automatically and displayed “as you input data” (HMI-3) • Will ensure consistency between digital/text • Will give confidence to the operator that the data was correctly input
Lessons Learned • Data synchronisation is important! • Baseline data • Digital NOTAM • NOTAM -> Checklist • Digital NOTAM • Assured delivery (digital signature) • Data synchronisation service is necessary for both static & dynamic data (APLI-1)
Scope Execution: Winter 2009-2010 • Service provider • Briefing • FPL • chart • FMS data • etc. • End user • Pilot • Airline OPS • ATC • etc. Originator (Digital NOTAM) Image Text Application AIXM 5 (Digital NOTAM) xNOTAM Trial (origination only) xSNOWTAM Trial (end-to-end)

Initial results • Surface Contamination model is validated • Including extra capabilities, • Detailed information for each Apron, TWY, stand • Portion of Apron covered by contaminant • Contamination percentage (very important for airlines) • Individual observation time for each element • Etc. • Very well received by airlines • Overview page – suggested by SAS and KLM • Perfectly feasible as operational application in 1-2 years • Report to AI-OPS: Poor compliance of issued SNOWTAM with ICAO specification • Complex N) & R) fields • Probably, for a good reason, but then the ICAO standard is in need for update… • Syntax errors in F, H, G
