Are you ready to save fuel and reduce both emissions and noise? We will help you to implement CCO and CDO.
The European CCO and CDO Task Force
Results of the study
1) The results indicate that in Europe the potential savings from optimising CCO and CDO are up to 340,000 tonnes fuel/year, (1.1M tonnes CO2/150M EUR) *; and,
2) The potential fuel saving benefits from CDO are in the region of x10 of those from CCO.
The results of the ECAC-wide study show that the potential benefits available to operational stakeholders are huge and therefore, in early 2018, the CCO/CDO Task Force was reactivated with the objective of identifying the following:
- What are the barriers to more CCO/CDO being flown?
- Which barriers can the CCO CDO Task Force address to achieve more CCO/CDO?
- What can ATM stakeholders do to promote more CCO/CDO?
The work of the Task Force is ongoing and is expected to be completed by 2019 with the delivery of an updated CDO Action Plan document and a “State of Play’ document on CCO/CDO.
More information will be detailed on the website once it becomes available.
As a result of the latest Task Force discussions, one of the parameters for measuring CDO has been updated. The CCO / CDO Task Force now recommends that a single level segment of up to 30 seconds, if undertaken at a level immediately prior to glide slope intersection, be allowed in the measurement of CDO and therefore the time taken for such an event will not be treated as inefficiency. For example, when a level segment of 45 seconds is flown prior to glide slope interception, only 15 seconds of a level segment will be recorded. This single 30-second event provides a realistic buffer for glide slope interception based on ‘distance-to-go’ accuracy, pilot technique and experience, non-constant wind values at different altitudes and some FMS capabilities.
The harmonised definitions, metrics and parameters for measuring CCO and CDO have been agreed between the members of the European CCO/CDO Task Force. The outcomes of the Task Force will remain stable unless detailed operational evidence is generated which suggests that the parameters for measurement of CCO/CDO on a harmonised pan-European level may be further optimised.
