  SESAR is supposed to boost the development of new operational procedures
together with the supporting systems in order to modernize the pan-European air
traffic management (ATM). One consequence of this development is that more and
more information is presented to - and has to be processed by - air traffic
control officers (ATCOs). Thus, there is a strong need for a software design
concept that fosters the development of an advanced (tower) controller working
position (A-CWP) that comprehensively integrates the still counting amount of
information while reducing the data management workload of ATCOs. We report on
our first hands-on experiences obtained during the development of an A-CWP
prototype that was used in two SESAR validation sessions.
