Abstract:
Both in Europe and the US, ATC delay seriously affects airline operations. Delays are expected to increase as air traffic increases in the future.

The ATC delay situation in Europe is serious. According to a EUROCONTROL study published in October 1999 (Medium- term Capacity Shortfalls 2003-2005) ""the average en route delay per flight by the year 2005 is estimated between 17.1- 36.8 minutes, according to the assumptions retained, if there is nothing more undertaken than national and supra- national Capacity Enhancement Plans known"" at that date.

Past studies conclude that digital data link is a key enabler to reduce delay. In 1995 the FAA published the results of a data link benefits study entitled ""User Benefits of Two-way datalink ATC Communications: Aircraft Delay and Flight Efficiency in Congested En Route Airspace"" in which ATC productivity was increased, thereby decreasing airline delay, by using datalink to reduce voice frequency congestion.

At the same time there are spectrum availability and congestion problems looming for airline current AOC operations, with the potential for a large negative economic impact.

As a part of the answer, the ICAO Aeronautical Telecommunication Network (ATN) provides an interoperable datalink network to support Air Traffic Services.
