ECHOES (EUROCONTROL - Consolidation of HMI for Operations, Evaluations and Simulations)

ECHOES specialises in the development, documentation, and evaluation of HMI functionality.



1) providing a support to study simulations, the SFM centre of expertise, and the ERIS programme by:
  • directly supporting the STCs and HF specialists in defining developing and documenting the HMI elements for individual studies, (e.g. CASCADE, G2G, AVT and EVP);
  • managing the operational and technical coherence and re-use of the different HMI elements, across studies, allowing STCs to concentrate on managing the issues of the study in hand; and
  • through the use of unified modelling processes, reducing the coupling between the specification and technical design of HMI functions and their realisation on a particular platform or software environment.
2) providing a focus for improvement and innovation in CWP HMI development by:
  • documenting both the new HMI elements, the requirements they meet, and the design rationale behind them in a form which allows re-use;
  • speeding up the process of making these new HMI elements available in study simulations, since the same methods and framework would be employed as to support the SFM centre of expertise; and
  • supporting the refinement of HMI propositions through tracing and consolidating the feedback from the different studies and activities which employ them.
3) providing continuity and a logical contact point and support for external activities such as CEATS (CRDS, CAPS), member states, and other activities mediated by AIS and STS.

Through its Style Guide, ECHOES encapsulates not only design solutions but also the design rationale and the knowledge of human cognition and performance that allows solutions to meet human as well as functional requirements.
4) providing a number of additional benefits through the centralisation of HMI development information, by:
  • supporting the migration from ESCAPE to ACE and, if correctly employed, managing the coherence between eDEP implementations and those on ESCAPE or ACE, through the provision of adequate documentation;
  • improving the process efficiency for HMI production for the Agency through consolidation of lessons learnt and re-use in the HMI area; and
  • within the EEC, specifically supporting the specification, development, and realisation of the ACE-based HMI for CASCADE, Gate to Gate, and EVP (subsequent to spring 2005).


HMI development is needed throughout the the ATM research and development lifecycle (from concept prototyping, through pre-industrial experimentation and simulation, to implementation and eventual system managment and evolution). Its significance is increasing steadily in terms of potential cost and risk in system development. This leads to consolidation and re-use of both software and specifications. If safety, quality and a variety of increasingly demanding regulatory requirements are to be met, this re-use must be properly managed and supported with a traceable design rationale and development history. In response, the mission of the ECHOES project is to provide an effectively documented process for establishing the HMI requirements associated with evolving ATM functions, and develop, test and maintain good quality HMI solutions to support all phases of the development lifecycle.


Specific objectives in Phase 1 are to:
  • create an integrated, thoroughly-documented set of HMI options for the EEC to coincide with the transition to ACE; and
  • establish effective procedures and process interfaces to integrate a wide range of ATM functions at the interaction /presentation level of the interface.


  • The CASCADE internal study (March 2005)
  • The Gate to Gate delivery (April 2005).
  • The ACE transition for EVP and the AMAN studies (early 2005).
  • The CASCADE study (Q3, 2005).


Application and extension of the development processes and UML based framework established by the CoRe Project (HRS/HSP-006). The framework allows the maintainance of separate Functional (Specification) and Component (Implementation) models linked in a coherent manner by a GLUE model. The GLUE model manages traceability and also provides document management and generation. The initial CoRe baseline was extended to provide HMI requirements and solutions for all the principal ATM functionalities currently available to EEC-supported projects. These are being delivered fully documented, tested, and running under ACE.

Expected Results

It is expected that ECHOES will result in a better understanding of the requirements for HMI to support future ATM functions.

Expected short-term results are better quality, faster, and more cost effective production of HMI for studies at the EEC.

Expected long-term results are a process for validating sound and safe HMI principles as the basis for operational improvements.
