Arinc424 specification
• Arinc424: “Navigation System Data Base”
• sets forth the air transport industry’s recommended standards for the preparation of airborne navigation system reference data files.
• Version 1 published in May 1975
• Version 19 published in December 2008 – applicable today
• Arinc424 committee
• 1 regular meeting per year to discuss on A424 change proposals

Arinc424 specification
• The Arinc424 specifies a format of navigation (and communication) data.• Plain text - lines of 132 alphanumeric characters• Navigation data: Airports, Runways, Navaids, Procedures• Communication data: Com Services (ATIS…)
• The Arinc424 scope is not restricted to FMS data – it also includes data for Flight Planning systems, Simulation tools…

NDBX concept / Arinc424-A
• Since 2006, a technical group formed inside AEEC has been studying the feasibility to define and standardize an open source format for embedded navigation databases => NDBX• based on the content of Arinc424 v.19 but restricted to FMS
perimeter• relying on a new UML model and on XML & Binary XML
representation of the data
• In 2008, the decision was taken by the AEEC to merge the existing Arinc424 specification and the NDBX standard => Arinc424-A

Eurocontrol’s involvement in Arinc424A
• 2006-2007: Eurocontrol participated in the initial NDBX committee and shared AIXM experience with the group
• 2007-2009: A Business Rules Working Group was formed inside the NDBX Committee, led by Eurocontrol and tasked with the development of an initial set of validation rules.
• 2010-2012: Eurocontrol continues to support the development of the A424A specification through its contribution to SESAR project 9.31.

SESAR WP9.31 “Aeronautical Databases”
• Scope of WP 9.31 • Structure and content of Navigation, Airport, Terrain &
Obstacle DB• Evolutions of the database production chain (focus on data
integrity, performance…)
• WP9.31 includes some interaction with the ARINC424A standardisation group for the integration of new navigation database requirements

SESAR WP9.31 “Aeronautical Databases”
• 2010: Produce business rules for Arinc424-A, following the methodology used for the AIXM 5.1 business rules
• 2010-2012:
ARINC 424A UML/XML/BXML
FMSSimulation
Define a set of mapping rules for conversion of ground sources (AIXM 5.1) into Arinc424A data (2011)
- Regulatory framework- Identify the most effective means to ensure data integrity- Recommendations for DB packing, verification, certification
Definition of Global Database Management Process
Practically – validation of NavDB chain
