Scandinavian Airlines concludes fuel saving approach trial

SAS Scandinavian Airlines (SAS) have concluded Europe’s first commercial green approach trial with the arrival of an Airbus A330, from New York’s Newark airport at Stockholm Arlanda Airport on 08 December 2007. The trial has been testing what SAS call a Continuous Descent Approach (CDA). SAS is carrying out the CDA program with partners Stockholm-Arlanda airport, Airbus and the Swedish state-owned aviation service company LFV.

SAS Scandinavian Airlines Airbus A330

SAS has carried out over 2000 CDAs on flights in Sweden with a Boeing 737 and on trans-Atlantic flights with an Airbus A330. A trans-Atlantic CDA with an Airbus A330 is estimated to save approximately 150 kilos of aviation fuel and 470 kilos of carbon dioxide (CO2).

Sigmund Lockert, Scandinavian Airlines’ Airbus 340/330 Fleet Chief Pilot, explains the trans-Atlantic CDA:

The approach carried out at Arlanda today was in fact very easy for us pilots. The engines were running at idle power from our cruise altitude, until the final stage of the approach. The aircraft’s Flight Management System was automatically flying the whole approach routing and the passengers conceived the approach as nothing but smooth and quiet.

Scandinavian Airlines will continue to test green approaches on trans-Atlantic flights from Chicago and New York to Stockholm arriving on off-peak slots. At present, this means flights arriving from the US on weekends. In a future optimized Air Traffic Management system, and assuming SAS International would conduct CDAs on all its approaches, an estimated 492 tons of fuel and 1,550 tons of CO2 would be saved per year.

  2. My name is Jim Stabile, I am a 23 year Captain for a major airline and I am the vice President of Aeronautical Data Systems Inc (ADS), a software/hardware development company located in Northwest New Jersey.

    ADS has solved an important flight planning issue for the aviation industry which results in substantial fuel reduction, cost savings, and carbon emissions reduction, as well as an increase in air safety.

    Quite simply, the airlines are operating inefficiently as their technology for calculating fuel consumption is outdated, and as a result they carry too much fuel (which requires them to burn more fuel to fly with the substantial additional weight). While the industry could handle the inefficiency previously due to low fuel prices, the exorbitant rise in fuel cost has caused the airline industry to operate in the red.

    ADS produces software and hardware that reduces fuel required on international flights of up to and over 11 percent, by accurately calculating the amount of fuel actually required for each flight. This technology has been used by corporate aviation for over 15 years, but the commercial market has been slow to respond due to lack of financial incentive. The savings are dramatic – up to $1.5 million per aircraft per year on international flights – as well as significant reduction in fuel consumption and carbon emissions.
