The Guidance Material for the development of the RP4 Monitoring Report is now available on the EU Single Sky Performance website.
Prepared by the Performance Review Body (PRB), the document supports National Supervisory Authorities (NSAs) in carrying out monitoring tasks for the fourth reference period (RP4) of the Single European Sky performance and charging scheme. The guideline material provides practical instructions for completing the monitoring template, including explanations and illustrative examples of the data inputs required.
The Guidance Material was developed in consultation with the NSAs and the NSA Cooperation Board.
The prefilled monitoring template is available for NSAs on the policy reporting platform.
