Prague Airport Is on the Road to Further Noise and Emission Reductions, Thanks to the CDM System

Prague 8/25/2011 

Starting at the end of August, ground operations at Prague Airport will follow Collaborative Decision Making (CEM) procedures. This will shorten the period necessary for aircraft to move on the ground, thereby reducing fuel requirements for the airlines, as well as cutting noise and emissions into the atmosphere from aircraft. 

CDM procedures are a modern method of managing aircraft operations at airports, based upon the timely exchange of precise, complete information concerning flights between all chief entities involved in aircraft operation (the airport, airlines, air traffic control and handling). Handling companies will send estimated times handling will be completed for departing aircraft which they will subsequently specify in greater detail. The airport control tower will use this information to calculate optimal times for starting engines so that the aircraft taxis to the runway in the optimum sequence and, where possible, without delay at the holding location. This makes for more fluid aircraft operations, better organization and increased safety for airport operations.

The use of CDM will allow aircraft taxi times during peak departure periods to be shortened by several minutes. The most frequently used aircraft at Prague Airport, the Airbus 320, consumes approximately 550 kg of fuel per hour. Each minute of taxi time saved will thus save the airline approximately 10 kg of fuel. The noise level around the airport will also be reduced by the use of CDM, as will emissions. The benefits brought by CDM will also be perceptible in winter, when there will be better coordination of aircraft deicing. 

CDM data from Prague Airport will be used in a further phase of the project by Eurocontrol to improve the regulation of the European airspace. CDM procedures are also used by large modern airports like those in Munich, Frankfurt, Zürich, Paris, Brussels and Heathrow in London. 

Aside from Prague Airport, others involved in the project include Air Navigation Services of the Czech Republic, Czech Airlines and Menzies Aviation (Czech). CDM procedures will also govern all other users of the Prague/Ruzyne Airport – aviation and handling companies. For more information, go to the Prague Airport website at:
