In Brussels, there has been a strong movement in favour of traffic restrictions at the airport, including a minister’s call for a ban on night flights from 23:00 to 07:00.
The background to this movement is likely to be a recently published study on the health effects of various factors at Brussels Airport. The content of this study is not completely new, but it is a very new and very careful summary and evaluation of existing specialised studies.
In point 2.5. of the summary at the beginning of this study, the political consequence is the recommendation of a ban on night flights from 23:00 to 07:00.
