ERA Wants More Continuous Descent Approaches in Europe

Board members of the European Regions Airline Association (ERA) have unanimously agreed to call for the use of CDAs (continuous descent approaches) at as many European airports as possible because of the system's beneficial effects on efficiency, the environment and flight safety.

ERA says it has long accepted the assertion that CDAs, also popularly known as "green approaches," are safer than traditional stepped approaches. Now the association is pushing for greater implementation of CDAs because its members believe the procedure also saves fuel, emits less CO2 and reduces noise.

Trials undertaken by Eurocontrol have shown that CDAs can reduce fuel burn 10 to 30% and noise up to 30%, which ERA says equates to a saving of between 50 and 150kgs of fuel and up to 450kgs of CO2 per flight.

Mike Ambrose, ERA's director general, notes that regional airports are less restricted than some of the busier major hubs such as London Heathrow or Frankfurt, and are therefore best placed to apply these procedures. "No special equipment is necessarily required, but it does entail enhanced cooperation between airlines, airports and air traffic service providers," Mr. Ambrose said.

ERA now plans to work closely with Eurocontrol to promote the implementation of CDAs at regional airports throughout Europe through collaboration with airlines, airports and air traffic services providers.  01-29-2008.
