First Airlines obtain ADS-B Airworthiness Approval

The airworthiness approval, covers Airbus, Boeing and Dassault airframes and allows ADS-B messages broadcast via 1090 MHz Extended Squitter to be used as the sole surveillance source for an air traffic control service. Currently Portugal, the Netherlands, Greece, Italy and Turkey are committed to implementing ADS-B in those parts of their airspace not covered by radar. The EASA approval is also valid in the Hudson Bay area of Canada where the ADS-B operational service will commence in November 2008. Approval by EASA of ADS-B use in European airspace is a major step forward and will create opportunities for fuel and emission savings, whilst enhancing safety levels, said Alex Wandels, Manager of EUROCONTROLs CASCADE programme. Following the approval from EASA, we know that the airlines are eager to begin using ADS-B in their daily operations, in addition to participating in trials. ADS-B relies on aircraft broadcasting their identity, position and velocity (both GNSS-based). This signal can be captured by receivers on the ground (ADS-B out) or on board other aircraft (ADS-B in). ADS-B is recognised as an essential element in SESAR and in the FAAs NextGen programme. A Single European Sky Implementing Rule mandating the carriage of ADS-B from 2015 onwards will be published for consultation in the coming weeks. Similar rules are being developed in Canada, Australia and the United States. EUROCONTROLs CASCADE programme co-ordinates the implementation of initial ADS-B applications in Europe. It performs trials, clarifies operational scenarios, drives the production of global standards and produces both safety and business cases, paving the way for operational approval. Implementation of ADS-B out is expected to start in Europe from 2009 onwards. For more information on the CASCADE programme, please visit the Web site: www.eurocontrol.int/cascade
