Replacement of the BUB beacon (phase 2) from 16 August until 30 September 2019


In the framework of the modernisation programme of the Belgian air navigation beacon network, skeyes will shortly be proceeding with the second phase of replacing the BUB beacon, located in the community of Kortenberg, close to Brussels Airport. 

The BUB beacon is used for en-route navigation and for take-offs from and landings at Brussels Airport.

The first phase of the BUB beacon replacement was performed from 8 November until 13 December 2018 (replacement of the electronics).

The second phase will take place from 16 August until 30 September (renovation of the metallic structure).

During this period, the BUB beacon will not be available for air navigation. As has been the case during phase one, procedures based on satellite technology (PBN) will be temporarily used for departures from and arrivals at Brussels Airport in order to remedy that unavailability. 

The PBN departure procedures have been designed using the current procedures as a basis. The use of these procedures during the first phase has shown that the impact on the followed trajectories was virtually non-existent.

PBN approach procedures will be published for runways 07R and 07L (as the other runways already have that type of procedure at their disposal). During the period that the BUB beacon will be unavailable, the approach corridor for  runway  07L landings will be slightly shifted because of the constraints resulting from that type of procedure (landing in the  runway  axis). That  runway  is not part of the preferential runway system and is only used when imposed by the meteorological conditions. The publication of that procedure will not modify the applicable regulation regarding the selection of runways in use. 

The temporary publication of those procedures is part of the international transition towards satellite technology for air navigation. In conformity with the European regulation, satellite-based flight procedures (PBN) will have to be published for all take-offs from and landings at Brussels Airport before 1 January 2024 at the latest.
