7. Mapping AICM 4.5 -> AIXM 5.1
The need for such a conversion:
Today, much aeronautical data is structured according to AIXM 4.5
It is expected that implementers will progressively move towards AIXM 5
A contract was awarded in November Objectives:
Entity to class mapping
Attribute to property mapping
Attribute value to property values
Processes involved in the mapping (merge of values…)
Mapping of AICM 4.5 geographical elements to GML
EUROCONTROL's Efforts with AIXM

8. Mapping AICM 4.5 -> AIXM 5.1
The deliverable is almost finalised.
It will be posted for review on the AIXM forum.
EUROCONTROL's Efforts with AIXM

9. Mapping AIXM 5.0 <-> AIXM 5.1 + xslt scripts
Part of the same contract
Objectives:
Provide a 5.0->5.1 mapping and a 5.1->5.0 mapping
Use a technique similar to the one employed for the 4.5-> 5.1 mapping
Limited to the list of differences between AIXM 5.0 and 5.1
Develop XSLT scripts implementing these rules
For the 5.1->5.0 mapping, an AIXM 5.0 extension will be created to gather the new AIXM 5.1 elements.

AIXM 5.1 Business rules
Definition of “business rules” has been standardized by OMG since Jan 2008
From wikipedia
Object Management Group (OMG) is a consortium, originally aimed at setting standards for distributed object-oriented systems, and is now focused on modeling (programs, systems and business processes) and model-based standards.
OMG provide only specifications, and does not provide implementations. But before a specification can be accepted as a standard by OMG, the members of the winning submitter team must guarantee that they will bring a conforming product to market within a year. This is an attempt to prevent unimplemented (and unimplementable) standards.
Other private companies or open source groups are encouraged to produce conforming products and OMG is attempting to develop mechanisms to enforce true interoperability.
Semantics of Business Vocabulary and Business Rules (SBVR), v1.0
This specification defines the vocabulary and rules for documenting the semantics of business vocabularies, business facts, and business rules;

12. AIXM 5.1 Business rules The need for AIXM 5.1 Business Rules:
Business rules for AIXM 4.5 must be adapted to AIXM 5.1 as data provider systems will gradually move towards AIXM 5
AIXM 5 does no longer specify mandatory properties or associations for a feature.
A contract was awarded in December 2009.
EUROCONTROL's Efforts with AIXM

13. AIXM 5.1 Business rules Objectives:
Define a set of AIXM 5.1 business rules based on:
AIXM 4.5 business rules
ICAO Annex 10, 11, 14 and 15 and the ICAO PANS-OPS
Temporality Concept document (including PropertiesWithSchedule)
Activation/Usage concept
draft AIXM GML profile
(Optional) Arinc424-A specification
Provide as a proof-of-concept an implementation of these rules in Schematron language
Upgrade Eurocontrol’s tool ARC which performs Schematron validation of AIXM data
EUROCONTROL's Efforts with AIXM

14. AIXM 5.1 Business rules
The result of this work will be an Excel report
Containing textual rules classified by type etc…
Providing Schematron code
AIXM Users will be able to pick-up the rules they need for their systems

15. eASM extension European “Flexible Use of Airspace” concept:
Airspace is no longer designated as purely "civil" or "military" airspace
Any necessary airspace segregation is temporary, based on real-time usage within a specific time period.
Contiguous volumes of airspace are not constrained by national boundaries.
Pan-European implementation has not been feasible in the past
Main problem: Data diversity
Terminology was different between civil and military stakeholders
EUROCONTROL's Efforts with AIXM

16. eASM extension The eASM extends AIXM 5.1 to support the FUA concept
The eASM Conceptual Model defines:
Airspace activation
Conditional route closure/activation
Military missions
The eASM XSD schemas are generated in compliance with the AIXM 5.1 UML to XSD mapping guidelines

19. Digital NOTAM Event Current NOTAM
19/04/2017
Digital NOTAM
Current 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.”
Digital NOTAM
Event
The current NOTAM is a text note, distributed by basic communication networks (AFTN). It is intended to be read by pilots, controllers and other operational personnel involved in flight operations.
By contrast, a digital NOTAM is small data set, made available through more advanced communication networks (such as AMHS). It is intended to be read and processed by automated systems, which in turn will convert it into text and graphical formats for presentation to humans (such as updated chart presented to the pilot or the controller) and might also trigger automated actions (such as determine procedures impacted by the event, etc.).
Basically, a digital NOTAM eliminates the free form text contained within a NOTAM and replaces the text with a series of structured facts about the affected aeronautical facility concerned. This is no longer presented as a “NOTAM message”. Instead, the information is exchanged in a format (text or even binary), which can be understood and used by computers. This requires that all the data currently exchanged by NOTAM is modelled and specified in a data exchange format.
This is a radical change.
The characteristics of a digital NOTAM include:
Geo-referenced - the information can be automatically plotted on a chart;
Temporal - the effective time can be computer interpreted;
Linked to static data - the change is cross-referenced to the baseline information;
Transformable – the information can be converted into any graphical or textual output, including the existing ICAO NOTAM format;
Query Enabled - a computer system can use complex queries to select temporary and last minute updates of interest based on user-specified criteria;
Electronically distributable - the information can be directly transmitted and incorporated into other computer systems without manual intervention.
“A data set made available through digital services containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to systems and automated equipment used by personnel concerned with flight operations.”
Requires data models!

20. Digital NOTAM Sample 19/04/2017
In a digital NOTAM, the current NOTAM fields do no longer exist. Instead, the information is structured using the Extensible Markup Language (XML), according to a schema pre-defined by AIXM. Every feature, every property and every possible situation needs to be identified by specific codes.
The challenge for AIXM version 5 is to model all these features and situations, knowing that the potential scope of NOTAM information is very wide.
As you can see, this is a computer format, suitable for automated processing but not suitable for human end-users. For pilots, controllers, etc, it will be necessary to translate the message into a graphical or textual description. These human readable formats are no longer constrained by the text message format of the current NOTAM.

21. What you can do with Digital NOTAM
19/04/2017
What you can do with Digital NOTAM
Digital data is much more clear/precise than free text:
Position of obstacles
Shape of restricted airspace
Schedules
Etc.
Digital data enables much more automatic validation checks:
For example, if THR is displaced, check if declared distances and OCA/OCH have been modified, etc.
Or, check the shape and location of a temporary restricted area
Check the shape and location of the airport surfaces that are work in progress or temporarily closed
Data quality
Manual workload

22. Digital NOTAM – Europe Roadmap
19/04/2017
Digital NOTAM – Europe Roadmap
2012 – 2014
ECAC States provide Digital NOTAM increment 1
Service providers and end users gradually use digital NOTAM on the ground
2015 – 2018
ECAC States provide Digital NOTAM increment 2
Service providers and end users use digital NOTAM on the ground and gradually in the air
The AI Team supports 2012 as start date
Proposed date (2014) for full operational capability for Increment 1 in ECAC is still TBC
Conclusion – AI Team report
“The Team agreed to support the Digital NOTAM implementation roadmap with the proviso that the proposed date (2014) for full operational capability for Increment 1 in ECAC be subject to further discussion and confirmation, taking into consideration national constraints and the need for synchronisation with other major changes impacting on AIS. In addition AIT accepted to provide comments to the Preliminary Business Case Report.”
The AI Team supported 2012 as start date!

26. Digital NOTAM Trial - 2008 Lessons learned:
19/04/2017
Digital NOTAM Trial
Lessons learned:
AIXM 5.0 model was sufficiently mature to support the Digital NOTAM concept.
Identified some modelling deficiencies, corrected in AIXM 5.1 (e.g. the “Usage” concept)
Demonstrated that with a relatively small investment (200 k€) it is possible to develop a basic HMI that can be successfully used by today’s NOTAM operators to provide the desired Digital NOTAM output
A similar trial has been organised by the FAA, focused on airport NOTAM submission.

The European Aeronautical Information Services Database (EAD) is a single, centralised repository of aeronautical information. It enhances quality of aeronautical data by using international standards and rigorous data-checking procedures, including in-depth validation and verification. Two main types of clients use EAD: Data Providers and Data Users.
EAD Data Providers
Data providers use the database to directly maintain and distribute their own aeronautical information. They retain full control of – and intellectual property rights over – the information they input into EAD. Data providers include:
Aeronautical Information Services (AIS) organisations within Civil Aviation Authorities, Air Navigation Service Providers (ANSPs) and military administrations from the European Civil Aviation Conference (ECAC) area; as well as
designated organisations which maintain data that does not fall under the responsibility of national agencies.
EAD Data Users
Data users consult and download data or aeronautical publications, and generate reports from EAD. Typical data users include:
data providers;
aircraft operators;
international organisations;
private pilots;
commercial users; and
the general public.
