Integrated Tower Working Position (ITWP)

Tower controllers today work with an increasing number of systems in order to meet the rising demand in air traffic at airports. At the EUROCONTROL Experimental Centre in Brétigny (EEC), a study was launched in January 2006 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 collaboration with air navigation service providers (ANSPs) and industry representatives, and continued its development under the SESAR Work Package (WP)6.

The project combined data from the Advanced-Surface Movement Guidance and Control System (A-SMGCS) with Electronic Flight Strips (EFS), meteorological data, 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 user friendly 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) description (available in the Project deliverables section below) and
  • three evaluation reports.

As part of the SESAR programme, the ITWP was further developed and extensively used in validation exercises for WP6 including using real surveillance data during a live trial at Riga Airport in January 2016. ITWP is a flexible platform that can be used to test industry prototypes and train personnel on the A-SMGCS Services –Surveillance, Airport Safety Support, Routing and Guidance. Different airport environments can also be incorporated with the possibility to include a 3D exterior view and it can be linked to cockpit and approach simulators to test other concepts such as Time Based Separation (TBS).
