Aviation Information Data Exchange (AIDX) is the global XML messaging standard for exchanging flight data between airlines, airports, and any third party consuming operational data. AIDX is generally used in the operational window of a flight, but there are implementations that have extended AIDX messaging considerably beyond this temporal scope.
AIDX is endorsed as a standard by:
- IATA Recommended Practice 1797A
- ACI Recommended Practice 501A07
- ATA Recommended Practice 30.201A
The current release of AIDX is a standard for SESAR A-CDM (Airport Collaborative Decision Making) information exchange, ACI ACRIS A-CDM Web Services and supported as the data exchange standard for A-CDM by ICAO (ICAO A-CDM Implementation Plan, Asia Pacific).
The AIDX Working Group develops and maintains the AIDX messaging standard to support the efficient and effective exchange of operational flight data across the aviation industry. Adoption of this industry data standards deliver substantial benefits to all stakeholders involved.
The Group comprises airlines, airports, IT Service providers, vendors and industry associations. Members may be involved in operational areas, architecting IT solutions, or responsible for maintaining Data Standards within their organizations.
Adoption of the AIDX industry standard delivers substantial benefits to airlines, operational partners responsible for updating operational flight information and industry stakeholders consuming operational flight data:
- Improved data quality and accuracy
- Support for A-CDM implementations
- Support for disruptive event use cases
- Increased flexibility/lower cost of integration with applications supporting an AIDX interface
- Increased agility in managing/modernizing a portfolio of operational applications with a standard AIDX interface
- Reduced numbers/simplification of IT adaptors needed for the exchange of e-data with business partners
- Leveraging of open source XML tools to process and analyse operational data
The schema was initially developed between 2005 and 2008 and involved over 80 airlines, airports and vendors interested in an XML message that exceeded the requirements of the IATA MVT (Movement) message. Currently the schema comprises around 180 distinct data elements covering multiple aspects of Operational Flight Legs such as:
- Flight Identification
- Line of Work
- Operational Times
- Disruption Detail
- Status and Remarks
- Airport Resource Requirement
- Passenger, Baggage, Fuel, Cargo statistics
- Aircraft Detail
AIDX is continuously developed to ensure it stays fit for purpose and it meets the evolving needs of the industry. Current development activities include:
- Incorporating change requests to meet changing and new business requirements (e.g. Supporting evolution of A-CDM towards Total Airport Management ‘TAM’)
- Developing a migration path for teletype messages such as MVT/MVA (+others as per AHM700) to AIDX standards to insure AIDX can fully replace teletype messages.
- Aligning AIDX with the IATA Airline Industry Data Model (AIDM) by modelling all AIDX data elements and attributes into the model.
- Requirements definition for a family of AIDX APIs (e.g. Departure, Arrival, Diversion, Delay)
- Cross-domain alignment and harmonization with other information exchange data models (e.g. AIRM supporting the FIXM message ).
IATA releases two versions of all schema each year, and there may not be AIDX changes within each releases. For this reason the Implementation Guide version may not be updated for each release.
