Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Aeronautics
(AERO).
The present document has been produced by ETSI in response to European Commission mandate M/390 for the
Interoperability of the European Air Traffic Management Network.
The present document has been developed in cooperation with Eurocae for compliance with the Essential Requirements
of the Single European Sky Interoperability Regulation [i.1] and/or requirements given in implementing rules for the
Single European Sky Interoperability Regulation.
The presumption of conformity which is linked to the full application of the present document can only be claimed after
the present document has been listed in the Official Journal of the European Union as Community Specification.
General and specific requirements for presumption of conformity to SES Interoperability Regulation 552/2004 as
amended by Regulation 1070/2009 are given in the normative annexes of the present document.
NOTE: Other requirements and other EU Regulations and/or Directives may be applicable to the product(s)
falling within the scope of the present document.

Introduction
The European Union launched the Legislation "Single European Sky" (SES) in 2002 which was adopted in 2004 and
amended by Regulation (EC) No 1070/2009 [i.1].
The SES legislation is based on a framework of 4 regulations, which includes the Interoperability Regulation [i.1]. The
objective of the Interoperability Regulation is to ensure interoperability of the European Air Traffic Management
Network (EATMN) consistent with air navigation services. Under this regulation, the use of a European Standard
referenced in the Official Journal of the European Union as Community Specification (CS) is a means of compliance to
the essential requirements of the Regulation and/or the relevant implementing rules for interoperability.

1 Scope
The present document is applicable to Air Traffic Management Airport Collaborative Decision Making (A-CDM).
The present document addresses the specific roles, responsibilities, procedures, systems and interfaces needed to fulfil
the Airport CDM (A-CDM) Operating Concept as requested by Mandate M/390 of the European Commission. It
references existing documentation where necessary to clarify the more detailed aspects of a procedure or system
implementation requirement to avoid unnecessary repetition.
Airport Collaborative Decision making (A-CDM) is about improving the way operational partners at airports and
European ATFCM (Air Traffic Flow and Capacity Management, Air Traffic Control, Airlines, Ground Handling
Agents/Units and Airports) work together at an operational level.
A-CDM allows an Airport CDM partner to make the right decisions for a flight during the whole Airport CDM process
in collaboration with other Airport CDM partners, knowing their preferences and constraints and the actual and
predicted situation. The decision making by the Airport CDM partners is dependent upon the sharing of accurate and
timely information and upon adapted Airport CDM procedures, mechanisms and tools.
Any software elements related to the software assurance level of an A-CDM System are outside of the scope of the
present document. As such the essential requirements of the Interoperability Regulation are not considered for software
elements within the present document.
The present document does not give a presumption of conformity related to maintenance requirements, safety,
civil/military coordination or environmental constraints.
NOTE: For these ERs, please refer to the Air Navigation Service Provider procedures.
Requirements in the present document which refer to "should" statements or recommendations in the normatively
referenced material (clause 2.1) are to be interpreted as fully normative ("shall") for the purpose of compliance with the
present document.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or

Introduction
The European Union launched the Legislation "Single European Sky" (SES) in 2002 which was adopted in 2004 and
amended by Regulation (EC) No 1070/2009 [i.1].
The SES legislation is based on a framework of 4 regulations, which includes the Interoperability Regulation [i.1]. The
objective of the Interoperability Regulation is to ensure interoperability of the European Air Traffic Management Network
(EATMN) consistent with air navigation services. Under this regulation, the use of a European Standard referenced in the
Official Journal of the European Union as Community Specification (CS) is a means of compliance to the essential
requirements of the Regulation and/or the relevant implementing rules for interoperability.
The present document takes into account the Council Decision 2009/320/EC [i.4] endorsing the European Air Traffic
Management Master Plan of the Single European Sky ATM Research (SESAR) project [i.4].

1 Scope
The present document is applicable to Air Traffic Management Airport Collaborative Decision Making (A-CDM).
The present document addresses the specific roles, responsibilities, procedures, systems and interfaces needed to fulfil the
Airport CDM (A-CDM) Operating Concept as requested by Mandate M/390 of the European Commission. It references
existing documentation where necessary to clarify the more detailed aspects of a procedure or system implementation
requirement to avoid unnecessary repetition.
Airport Collaborative Decision making (A-CDM) is about improving the way operational partners at airports and European
ATFCM (Air Traffic Flow and Capacity Management, Air Traffic Control, Airlines, Ground Handling Agents/Units and
Airports) work together at an operational level.
A-CDM allows an Airport CDM partner to make the right decisions for a flight during the whole Airport CDM process in
collaboration with other Airport CDM partners, knowing their preferences and constraints and the actual and predicted
situation. The decision making by the Airport CDM partners is dependent upon the sharing of accurate and timely
information and upon adapted Airport CDM procedures, mechanisms and tools.
Any software elements related to the software assurance level of an A-CDM System are outside of the scope of the present
document. As such the essential requirements of the Interoperability Regulation are not considered for software elements
within the present document.
The present document does not give a presumption of conformity related to maintenance requirements, safety, civil/military
coordination or environmental constraints.
NOTE: For these ERs, please refer to the Air Navigation Service Provider procedures.
Requirements in the present document which refer to "should" statements or recommendations in the normatively
referenced material (clause 2.1) are to be interpreted as fully normative ("shall") for the purpose of compliance with the
present document.

Introduction
The European Union launched the Legislation "Single European Sky" (SES) in 2002 which was adopted in 2004.
The SES legislation is based on a framework of 4 regulations, which includes the Interoperability Regulation [i.2]. The
objective of the Interoperability Regulation is to ensure interoperability of the European Air Traffic Management
Network (EATMN) consistent with air navigation services. Under this regulation, the use of a European Standard
referenced in the Official Journal of the European Union as Community Specification (CS) is a means of compliance to
the essential requirements of the Regulation and/or the relevant implementing rules for interoperability.

1 Scope
The present document is applicable to Air Traffic Management Airport Collaborative Decision Making (A-CDM).
The present document addresses the specific roles, responsibilities, procedures, systems and interfaces needed to fulfil
the Airport CDM (A-CDM) Operating Concept as requested by Mandate M/390 of the European Commission. It
references existing documentation where necessary to clarify the more detailed aspects of a procedure or system
implementation requirement to avoid unnecessary repetition.
Airport Collaborative Decision making (A-CDM) is about improving the way operational partners at airports and
European ATFCM (Air Traffic Flow and Capacity Management, Air Traffic Control, Airlines, Ground Handling
Agents/Units and Airports) work together at an operational level.
A-CDM allows an Airport CDM partner to make the right decisions for a flight during the whole Airport CDM process
in collaboration with other Airport CDM partners, knowing their preferences and constraints and the actual and
predicted situation. The decision making by the Airport CDM partners is dependent upon the sharing of accurate and
timely information and upon adapted Airport CDM procedures, mechanisms and tools.
Any software elements related to the software assurance level of an A-CDM System are outside of the scope of the
present document. As such the essential requirements of the Interoperability Regulation are not considered for software
elements within the present document.
The present document does not give a presumption of conformity related to maintenance requirements, safety,
civil/military coordination or environmental constraints.
NOTE: For these ERs, please refer to the Air Navigation Service Provider procedures.
Requirements in this EN which refer to "should" statements or recommendations in the normatively referenced material
(clause 2.1) are to be interpreted as fully normative ("shall") for the purpose of compliance with the present document.
