DIFLIS is in operation at Vienna Tower since October 2005. The
installation consists of 6 Display Terminals and 2 redundant Servers
being connected to the fligth data processing system as well as
to the gate management system of Vienna Airport Authority.
The system uses a touch panel that is built into the console
table. It uses a pen input device, allowing the air traffic controller
to rest the palm on the screen without inadvertently making inputs.
