This section analyses ANS-related inefficiencies on the arrival flow at the top 30 European airports in terms of arrival ATFM delay
and additional ASMA time
Airport arrival ATFM delay by airport (2017 vs. 2016)
Average airport ATFM delays at the top 30 European airports decreased from 1.36 to 1.25 minutes per arrival in 2017. Although from a very high level
(11 min per arrival in 2016), the most notable improvement in 2017 was observed for Istanbul Sabiha Gökçen Airport (SAW) where ATFM arrival delay
reduced by 5.5 minutes on average.
Compared to 2016, the average delay per arrival increased notably at Amsterdam (AMS), London (LGW), and Lisbon (LIS). Due to its high traffic volume and the further increase in 2017, Amsterdam (AMS) had the highest impact on the network. Almost half of the total airport arrival ATFM delay in the EUROCONTROL area was generated by five airports: Amsterdam (13.8%), Istanbul Sabiha Gökçen (11.2%), Istanbul Atatürk (8.3%), London Heathrow (6.9%), and London Gatwick (5.3%).
Overall, the average additional ASMA time increased slightly in 2017.
As was the case in previous years, London Heathrow (LHR) stands out with an average additional ASMA time of more than 8 minutes per arrival and accounted for one quarter of the total additional ASMA time at the top 30 airports in 2017. LHR’s performance results from decisions made during the airport slot allocation process, and agreed with airspace users, to ensure constant demand in order to maximise the use of scarce runway capacity.
Please note that the ASMA results for some airports only include Jan-Nov data. The final figures will be updated with complete annual data.
Top 30 airports
no consistent time series available
Different from previous years, the data analysed is based on data directly provided by airport operators. Unlike CODA data, the Airport Operator Data Flow covers all departures from airports and is therefore also used for the analysis of additional taxi out and ASMA times. As highlighted in PRR 2016, while the data flow has a better coverage, some data quality issues do exist.
The average additional taxi-out time decreased slightly at the top 30 airports in 2017 from 3.9 minutes to 3.8 minutes per departure (excluding the two Istanbul airports for which no data was available).
In 2017, the highest levels of average additional taxi-out times were observed at London (LHR), London (LGW), Rome (FCO), Barcelona (BCN) and Dublin (DUB). At the same time, notable improvements were observed at Paris (CDG), Madrid (MAD), Copenhagen (CPH), Rome (FCO) and Lisbon (LIS).
