As rapid as paper strips ? Evaluation of VertiDigi, a new control tool for terminal sectors

Abstract : VertiDigi is a vertical view of the flights in a terminal sector. The view, on a touch sensitive screen, tries to provide a similar service to controllers as the current paper Strips do: a tool to input control clearances naturally, intuitively and at a speed sufficient to allow the traffic to be efficiently managed. In arrival sectors, an Arrival Manager (AMAN) is often used. The AMAN delays in minutes can also be expressed on the vertical view as a moving target (ball indicating the desired position) for each flight. The resulting ball train is a novel way of representing an arrival sequence in a perceptive analog way. Experiments were conducted with 8 air traffic controllers from Paris ACC to compare VertiDigi vs. Strips input times, to assess the acceptability of the vertical view, and to estimate usability of the ball train The most evident outcome is that input times are in the same order of magnitude as papers Strips, and promising to be even shorter with minimal training. Meanwhile, the vertical view did not affect the controllers? mental view of the traffic. The ball train, in turn, did not yield better usage, performance or acceptance than the current AMAN Human Machine Interface (HMI).
