Users Bandwidth in Air Traffic Management: An Analysis from the HMI Point of View

Christophe Mertz and Raïlane Benhacène

This paper focuses on communication and information flows in the ATC system. We first identify the various information channels in ATC. The bandwidth of channels involving a human operator is considered a major limitation in the performance of the overall ATC system. This bandwidth could be increased, provided that adequate Human Machine Interaction techniques are implemented. Examples based on DigiStrips and other prototypes developed at CENA are then used to demonstrate how the users bandwidth could be dramatically increased. These proto types are mainly based on touch screen technology, simple gestures recognition, graphic design, and animations. They enhance system input, and system output as well as communications between close or distant operators.
