ATS Systems

Objective

The objective of the FASTI ATS Systems activity is to produce guidance material that can assist ANSPs in the procurement and system providers in the development of controller tools.

This guidance material takes the form of operational requirements derived from the operational services and environment description, supplemented with information on implementation options and feedback from validation.

The aim is to facilitate an ANSPs choice of capabilities to maximise their return on investment.

From the point of view of an ANSP the guidance material will provide assistance in identifying:
  • the capabilities of the controller tools required to support the chosen concept and working method.
  • the required performance of the supporting ATM system.
From the point of view of an ATM systems supplier the guidance material is to assist in the development of controller tools as part of an integrated ATM system.

The guidelines:
  • provide sufficient detail to specify unambiguously the required capabilities.
  • allow the reader to take maximum benefit from various validation exercises.
  • do not constrain the system design.

What has happened?

A number of pre-operational systems have been identified as major contributors to a FASTI ATC System Baseline Survey; iFACTS (UK) and ERATO (France). These systems have been analysed and their specifications merged into the FASTI ATC Systems Baseline.

In performing this analysis the common, core capabilities of the systems have been identified. Variable capabilities specific to particular variations of the operational concept have also been identified. The Systems Baseline provides examples of implementations which illustrate possible approaches to achieving and operational requirement.

Existing EATM Operational Requirements documents for the FASTI tools Medium Term Conflict Detection (MTCD) and Monitoring Aids (MONA) and the enabler, Trajectory Predictor (TP) are being rescoped and updated by the FASTI team using relevant expertise and experience form ANSPs and industry.

ATS System implementation guidelines for ANSPs are being developed which will provide support for the successful implementation in the following areas:
  • HMI principles
  • Tools integration
  • Trajectory prediction
  • Interoperability
  • Performance Requirements

The use of conflict detection tools, such as MTCD, relies heavily on the performance of the trajectory prediction function. Knowing the performance of the trajectory predictor is essential in optimising the local system.

The trajectory prediction analysis tool (TPAT) has been developed to measure the accuracy of a trajectory prediction (TP) function in a given environment and thereby allowing the performance of an MTCD to be predicted. The use of TPAT is now a mainstay of FASTI implementation support to ANSPs, particularly in support of the following activities:
  • System evaluation and acceptance;
  • MTCD parameter tuning;
  • Investigation and validation of TP improvements.
A pilot study of the new flight data processing system (N-FDPS) at the Maastricht Upper Area Control Centre (MUAC) was performed in March 2009. On completion of this first pilot study, a second one was performed at Budapest ACC.

Plans

Since a number of other ANSPs have already expressed an interest in TPAT, analyses will be performed during 2010. This will help them to tune their TPs for optimum performance, and subsequently to tune their MTCDs to give a workable trade-off between adequate warning time and unwanted or nuisance warnings.
