Description

In 2020, a new Pan-European CCO / CDO Action Plan was adopted. The Action Plan includes new harmonised definitions, metrics and parameters to measure CCO and CDO operations in Europe, developed by the European CCO / CDO Task Force. The Action Plan introduces the Noise CDO (focusing on optimising that part of the arrival profile where noise is the primary environmental impact) and the Fuel CDO. The Fuel CDO measures the environmental performance of the entire arrival phase from top of descent, in terms of fuel burn / CO2[1].
