FASTI - Operational implementation

The main objective of the Operational Implementation activity was to produce guidance material and support the operational implementation of the FASTI controller tools.

FASTI Operational Concept

An Operational Concept for FASTI (pdf) has been produced which provides a common target concept for FASTI, containing information on:

  • Operating Principles
  • Environment
  • Assumptions and dependencies
  • Working methods
  • Implementation issues
  • Current local implementations

ATC Manual


The ATC Manual of Operations (pdf) (a guideline for FASTI tools implementation) has been produced which provides guidelines for ANSPs, ATM related industry (system providers) and regulators, for the implementation of conflict detection tools (CDT), MONA and SYSCO in a coordinated way ensuring common operating procedures and interoperability between ATC centres within the ECAC area.


FASTI Demonstrator

The FASTI demonstrator has been developed to demonstrate in a visual and interactive way the operation of the FASTI tools set and communicate the FASTI operational concept.

The FASTI Demonstrator has been developed as an implementation of the FASTI Operational Concept. It incorporates the FASTI tool set supported by an interactive HMI which enables the concept to be demonstrated and described.

A CD with a version of the FASTI Demonstrator can be obtained from EUROCONTROL.

Human Factors

FASTI Human Factor case

The objective of the FASTI Human Factors (HF) activity was to carry out a Human Factors Case, a cognitive task analysis and develop requirements and guidelines for Human Factors in FASTI Implementation. The HF Case Process has been applied to the FASTI tools to provide a framework to document and manage HF issues for the FASTI Programme.

Cognitive Task Analysis is a method for decomposing a task into its subcomponents and for describing the strategies and mental processes that underlie the task. The cognitive processes considered were: attention, perception, working memory and long-term memory, cognition and decision making, and response execution.
On the basis of the CTA, benefits and potential issues were identified. Benefits refer to those that become easier and less prone to error with FASTI tools; issues refer to new tasks or tasks that become more demanding and more prone to error with FASTI tools. Recommendations on training, system and HMI design, and working methods were made that can help to manage the identified issues.

A set of good practice guidelines focusing on HF has been developed to help with the planning and management of the transition to the FASTI tools. Data was collected from ten Air Navigation Service Providers (ANSPs) within Europe to document the lessons learned from their experiences of implementing new tools to support controllers. In 90% of the cases the FASTI tools will be implemented as part of a new ATM system, so the scope of this data collection needed to be wider than the FASTI tools themselves. Practices and trends were reviewed for managing the transition to a new system/tool which focused on the following HF categories:

  • Human in System,
  • Procedures, Roles and Responsibilities,
  • Teams and Communication,
  • Training,
  • Organisation and Staffing.


FASTI Operational Safety Analysis

The objectives of the FASTI Safety and Regulatory Requirements activity were as follows:

  • To produce a Preliminary Safety Case for the FASTI tools implementation to serve as a basic document for ANSPs to produce local safety cases for use of FASTI related tools.
  • To provide guidelines for development of these Safety Cases.
  • To provide guidelines for national regulators in order to enhance regulation and especially licensing of the ATM systems introducing FASTI tools.
  • To collect "best practices" and existing experiences and incorporate them into to the guidelines. From the point of view of an ATM systems supplier, the guidance material aims to support the development of controller tools as part of an integrated ATM system

With regard to the overall claim that FASTI will be safe for operational use, The FASTI Preliminary Safety Case has shown that the FASTI concept and high-level design can satisfy this claim in the proposed operational context.

A number of Safety Issues remain to be addressed before this claim can be fully substantiated, but none of these are seen as being particularly difficult to resolve in principle. The main needs for the future are to ensure that adequate ANSP input is obtained, and that appropriate simulations are carried out Safety Case Guidance for ANSPs was produced to assist stakeholders by identifying key areas in which ANSPs will need to review or develop the Arguments and Evidence in parallel with their evolving detailed design and plans for implementation.


FASTI Operational Performance Analysis

The FASTI Operational Performance Assessment (OPA) aimed to provide a methodology to allow the determination of minimum operational performance requirements for the Conflict Detection Tools (CDT) within certain assumptions and scope limitations. The focus was on those aspects of the CDT system that impact the usability and the performance of the tool under nominal operation (success approach).

The design and implementation of these tools, such as the Conflict Detection Tool (CDT) can be a complex and lengthy process. A guideline methodology that can bring the operations experts together with the technical experts early in the requirement definition process provides a more efficient and effective deployment of controller tools meeting the expected performance levels.

The resulting methodology is designed to be used in conjunction with the Trajectory Prediction Assessment Tool (TPAT), though it can be used also across other tools and ATC functions.


Arrival Manager

As a late addition to the FASTI Programme the objective of AMAN software is to assist, through dedicated automation, in the management of the flow of arriving traffic in a particular airspace and to particular points (i.e. runway thresholds or metering points).

Its main aims are to:

  • Optimise the arrival traffic (sequence)
  • Regulate/manage the flow of aircraft to improve predictability, reduce workload and at the same time minimise the impact on the environment (meter)

Previous activities within ATC Domain of EUROCONTROL carried out a survey of the status of the various AMAN implementations across Europe in 2009 resulting in the AMAN Status Review 2009 and in 2010. As a result of the 2009 review it became clear that there are various interpretations of what constitutes ‘arrival management functionality’ and that defining or classifying all the different types and levels of automation used in arrival management is a complex task.

Resulting from the 2009 review a consolidated set of guidelines for AMAN implementations documenting the experience gained by ANSPs during their AMAN development has been produced. These are aimed at providing assistance both for new and ongoing implementations.
