Aeronautical information management

The Aeronautical Information Management service unit collects, assembles, publishes and distributes data on the Swiss aviation infrastructure. As the authoritative source for Swiss aeronautical information, AIM services provides quality-assured and tailored data and information to ATM and airspace users 24 hours a day.


In addition to data and information, AIM services also provides a centralized ATS Reporting Office (ARO) and an expert help desk for supporting pilots. AIM services is also home to the international NOTAM office for Switzerland.
The timely availability of high-quality aeronautical information fosters safe, efficient and environmentally sound operations for ATM and airspace users.



Products & Services


Aeronautical Information Publication (AIP/IFR)

The AIP manual for IFR (Instrument Flight Rules) contains information relevant to operations under IFR. It contains rules and procedures relevant to IFR operations within the airspace managed by skyguide. The AIP lists all IFR aerodromes in Switzerland, along with their SID/STAR procedures. The manual complies with the ICAO Annex 15 rules for such publications. AIM services publishes changes to the AIP manual every 28 days. It is only available electronically via our briefing service www.skybriefing.com.


International AIP library and screening service

The AIM Operations service manages aviation documents from over 160 countries around the world.

The continuous updating and quality checking of these publications forms the basis for comprehensive information and advisory tasks.


Official, updated documents are indispensable for a flight to be safe and successful.


A screening process allows aviation manuals to be filtered and read out according to customer-specific criteria. The resultant data sets are made available to customers electronically.


Providers of flight planning software and software developers interested in this screening service can contact , Tel. +41 43 931 62 32 for more information.

Aeronautical Information Circular (AIC)

AIC is a document containing information that does not qualify for the publication of a NOTAM or for inclusion in the AIP, but rather relates to flight safety, air navigation, technical, administrative or legislative matters (ICAO Annex 15).

skyguide maintains two series for the AIC. Information that needs to be distributed internationally are in AIC Series A, and information of national relevance is distributed in AIC Series B.

The AIC series are available for download here.


VFR Manual

The VFR Manual contains all the rules relevant to operations under Visual Flight Rules (VFR). It also contains an aerodrome section that lists most of the VFR aerodromes in Switzerland, along with the Area charts and Visual Approach charts for each aerodrome.

The VFR manual is available in paper form. An electronic version can also be accessed on our briefing platform www.skybriefing.com.
For software developers who wish to integrate the VFR Manual in their applications, a special license agreement is available. Please contact us at 



  • ICAO Chart Switzerland 1 : 500 000
    The ICAO chart provides aeronautical information that is useful for VFR pilots.
  • Glider Chart Switzerland 1 : 300 000
    The Glider Chart shows aeronautical information that is useful to glider pilots
  • Area Chart for Geneva and Zurich 1: 250 000
    Area Charts for the terminal areas for the Geneva and Zurich airports are available.
  • En-Route Chart (ERC) lower and upper for Switzerland
    The En-Route Charts showing the ATS routes for the lower and upper airways can be found on www.skybriefing.com in the Publications section.


Daily Airspace Bulletin Switzerland (DABS)

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 entire Swiss territory of parts thereof such as MIL night flights are listed on the text side of the DABS only.


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 area constantly updated. Therefore, the information status of DABS and the corresponding NOTAM is not identical anymore. Chart scale 1:1’250’000, in format A4.

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


Please contact the flight information service (FIC) or KOSIF (telephone number +41 44 813 31 10) for the latest information.


Not published in the DABS are airport information, NOTAM regarding procedure changes, information regarding obstacles and navigation aids, etc., as well as airspaces as published in the AIP (including HX airspaces) and R-Areas with special rules for gliders. For detailed information refer to the original NOTAM.


In accordance with ICAO regulations, all navigation warnings will also be promulgated by NOTAM.
This allows a complete briefing regarding dangers, limitations and changes in Swiss airspace either by DABS or by NOTAM collection.


For detailed information always refer to the NOTAM.
The DABS publication can be accessed on www.skybriefing.com



skybriefing provides functionality for flight preparation anywhere, at any time via www.skybriefing.com. It is the official pre-flight preparation service approved by the Federal Office of Civil Aviation (FOCA).

skybriefing integrates flight plan functions, meteorological information and NOTAM information in a single application. This enables the compilation, management and submission of flight plans and the creation of Pre-flight Information Bulletins (PIB) with meteorological and NOTAM information specifically tailored to the flight plan.
After registration on www.skybriefing.com, the application can be accessed from any internet-connected terminal, or from any self-briefing station available at aerodromes in Switzerland. The service is available 24/7 and 365 days a year. An expert support service is also available in support of skybriefing, and enquiries related to flight plans or NOTAM. It can be reached by telephone on +41 43 931 61 61 or by e-mail at .


International NOTAM database and delivery service

AIM Operations have a worldwide NOTAM database with the option of retrieving NOTAM information individually in line with customer requirements.


The NOTAM Database Service provides an up-to-date NOTAM database that can be accessed via system interfaces. In this way, NOTAMs can be imported easily into flight planning applications.

The NOTAM Database Service offers the following functions:


  • Collection of worldwide standard ICAO NOTAMs and diverse regional additional non-ICAO standard messages
  • Interface to NOTAM database via structured XML messages and web service technology
  • Extended, reduced and adapted scope after implementation
  • Active management of the NOTAM series in collaboration with the international NOF


Providers of flight planning software and software developers interested in integrating NOTAM can contact , Tel. +41 43 931 62 32 for more information.


Aeronautical Data

skyguide AIM is the authoritative source for aeronautical data in Switzerland. While the data is published in the AIP or VFR Manual, it can also be obtained in AIXM 5.1 or other formats on request.


Obstacle Data

Information on aeronautical obstacles can be found via the WEGOM application (WEb-Gis Obstacle Map) using the link below. For further information, see AIC B 004/13 APR 04 (available in German and French only).
