Environment - Austria
PRB monitoring
▪ Austria achieved a KEA performance of 1.92% compared to its reference value of 1.90% and, therefore, did not contribute positively towards achieving the Union-wide target.
▪ The NSA explained that KEA is highly sensitive to traffic, which on some days increased to 80% of summer 2019 levels and caused KEA to exceed 2%. Moreover, adverse weather and airspace users’ choice for longer routes were said to affect the results.
▪ However, the PRB notes that Austria’s daily traffic variation data shows that it managed at 63% of its 2019 summer traffic levels. Thus, the reasoning is not consistent with the data.
▪ Only one out of six Austrian airports that are regulated reported terminal data.
▪ While the share of flights operating CCO/CDO at Austrian airports improved in 2020 compared to 2019, the CCO performance was at a similar level as 2017 despite less terminal congestion. The additional time airspace users spent taxiing or holding in terminal airspace reduced by 36% compared to 2019.
