2.1 Features

We can identify two families of functionalities expected from integrated systems in terms of information and communication.

• Streaming on-line visualization of aircraft movements in real or delayed time: description of flight path, height and identification of aircraft, and instantaneous sound levels (L _eq short) recorded by overflight stations. The sound levels transmitted are raw values, without metrological validation, which limits the interest of this web visualization to a demonstration of the airport authority's desire for transparency.

• Once the data has been validated and processed, the statistical information can be used to assess noise...
