xNOTAM Trial – closed NOV 2008

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

Execution of the Trial

Lessons learned Incremental implementation ! 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 Assured delivery (digital signature) Data synchronisation service is necessary for both static & dynamic data (APLI-1)

Digital SNOWTAM Trial (2009-2010)

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
