Integrated Tower Working Position (ITWP)

Tower controllers today work with a steadily increasing number of systems which give them information. At the Experimental Centre in Brétigny (EEC), we decided to see how to best combine various airport air-side system components into an Integrated Tower Working Position (ITWP).

The EEC’s Airport experts started working on the ITWP project in January 2006, in collaboration with air navigation service providers and industry representatives, continuing its development under the SESAR Work Package 6.

The project combined data from the Advanced Surface Movement Guidance and Control System (A-SMGCS), electronic flight strips and meteorological data with Airport Safety Nets, Routing and Planning, Guidance, stand and gate management, data link and Air Traffic Flow Management tools in order to:

  • develop commonly agreed functional specifications and associated requirements;
  • develop a human-machine interface (HMI);
  • demonstrate ITWP’s potential using the Early Demonstration & Evaluation Platform (eDEP);
  • carry out simulations to evaluate the functional specifications, the HMI, human factors and safety requirements.

Over the course of the project, the ITWP team produced

  • an initial study report,
  • functional requirements,
  • human-machine interface (HMI) solution specifications and
  • three evaluation reports.

As part of the SESAR programme, the ITWP was further developed and extensively used in validation exercises for WP6. A new document, describing the current  ITWP HMI has been recently released and is available in the Project deliverables section below. 

Many new alerts for non-conformance with Air Traffic Control procedures and instructions have been identified; they will deliver significant operational safety benefits. In the future, ITWP will also integrate Arrival and Departure Managers linked with Airport CDM.
