The EUROCONTROL Performance Review Commission (PRC) has just prepared an independent review of how European air navigation services (ANS) performed in 2022, which is now open for stakeholder consultation. The draft 2022 Performance Review Report (PRR) concludes that even though traffic was still below 2019 levels, ANS performance in Europe deteriorated notably in 2022, and contributed to the poor overall air transport performance. Average en-route air traffic flow management (ATFM) delay rose to similar levels as in the capacity crisis years of 2018/19; while part was driven by air traffic management system upgrades, a significant component of delay was attributed to capacity shortfalls, with not all air navigation service providers able to deploy sufficient capacity to handle demand. The war in Ukraine also had a particularly negative impact on airspace availability and flight efficiency in 2022. (....)
