Guidelines for a continuous descent approach (CDA) into Paris should be published shortly following testing of the procedure conducted through the Atlantic initiative to reduce emissions (Aire).

Aire is a joint initiative among several airlines, the European Commission and the FAA to accelerate the application of new technologies and operational procedures that cut carbon emissions, noise pollution and conserve fuel.

In 2009 Aire completed roughly 1,152 flight trials in Madrid, Paris, Stockholm, Santa Maria and Reykjavik.

Of the 435 total flights executed in Paris 82 combined were dedicated to tailored arrivals into Charles de Gaulle airport and tailored arrivals and CDAs into Orly during low density operations, said Celia Alves Rodrigues, Environmental officer of the Sesar joint undertaking.

During the ICAO Colloquium on Aviation and Climate change on 13 May, Rodrigues said the CDA procedure for Paris will be published shortly.

About 620 flights were conducted in Madrid using CDA during night operations, and the CDA procedure is expected to be introduced into day-to-day operation at Madrid-Barajas airport this year, says Rodrigues.

Sesar estimates the 1,152 Aire trials performed in 2009 averaged CO2 savings per flight ranging from 90kg (198lb) to 1,250kg (2,755lb).

Air France and American Airlines completed Aire flights from Paris to Miami in early 2010.
