An extended analysis of sequencing arrivals at three major European airports

This paper presents an analysis of the sequencing of arrival flights at three major European airports representative of different types of operation with more than 24000 aircraft pairs.

The motivation is to better understand and characterise how sequencing is performed in dense and complex environments during peak periods. The analysis, purely data driven, focuses on the dynamic of spacing over time, investigating in particular convergence and reactionary aspects.

The two main results are:

1) progressive convergence of the spacing with a deviation up to ±2.5min at 10min to final, and ±50s at 5min to final; and

2) noticeable reactionary effect with a queue additional time up to 3min at 10min to final and 50s at 5min to final. These values may reflect the level of difficulty and sensitivity of sequencing during peak periods in such dense and complex environments. Future work will involve analysing high and late reactionary situations, investigating how this approach may help identifying improvement areas, and assessing the impact of a change for future operations.

This study has been conducted as part of the European SESAR2020 programme (PJ01-02).
