DABS - Daily Airspace Bulletin Switzerland

The DABS is an official Swiss aeronautical publication and provides the current airspace status at the time of retrieval, as information source for VFR aviation and in accordance with the NOTAM publications. NOTAM affecting the whole Swiss territory of parts thereof such as MIL night flights are listed on the text side of the DABS only.

For detailed information always refer to NOTAM E.g. through our OneClick Briefing.

Contents of DABS: dangers, restrictions and changes of airspace within Swiss territory, including activations of TEMPO CTR and TMA and military firings above 250 m/AGL.

The DABS chart for the current day is updated every day regardless of changes at: - 09:00 LT
- 13:00 LT
- 16:00 LT

The DABS chart for the following day is published at 16:00 LT. DABS updates contain reductions or cancellations of activities, if reported. The extension of an existing activity or the publication of new area is generally not possible with two exceptions:
- the 16:00 LT chart may contain MIL night flights and RPAS (Remotely piloted aircraft systems) flight for the current night
- for urgent and unexpected restricted areas established by FOCA.
The appropriate NOTAM are constantly updated. Therefore, the information status of DABS and the corresponding NOTAM is not identical

The DABS is published by skyguide AIM Services, section KOSIF (coordination office for firings and safety of air navigation).

DABS is not constantly updated in case of cancellations of airspace restrictions. Please contact the flight information service (FIC) or KOSIF telephone +41 44 813 31 10 for latest information.
