Monitoring network performance

The SES Performance Scheme requires the pro-active management, monitoring and reporting of pan-European operational performance targets covering safety, capacity, environment and cost-efficiency.

ATM network performance reports

We provide regular, timely and accurate reports on the overall performance of the network. These help us monitor and understand how the network is performing and take action when a problem occurs, and provide different views on the situation of the ATM network:

European Route Network Improvement Plan - Monitoring Report

The design of the European Route Network, as described in Annex 1 of EC Regulation No 677/2011 (the Network Management Implementing Rule - NMIR)  calls for the establishment of a European Route Network Improvement Plan as part of the Network Operations Plan and is developed through a cooperative decision making process. The ERNIP Implementation Monitoring Report gives an overview of the airspace design improvements and it's contribution to flight efficiency based on the proposals implemented during the relevant AIRAC cycle. The latest monitoring report can be found below, together with further information on Airspace Design:
