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 available either as a paper manual or as an electronic version on CD-ROM (compliant with Eurocontrol eAIP specifications).

Subscriptions can be ordered here.

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 

VFR Guide

The VFR Guide can be found on www.skybriefing.com in the Publications section.

Daily Airspace Bulletin Switzerland (DABS)

The DABS provides the current airspace status at the time of publication. It is an information source for VFR aviation and is published in accordance with the NOTAM publications.

Contents of DABS: dangers, restrictions and changes of airspace within Swiss territory, including activation of TEMPO CTR and TMA and military firings above 250 m/AGL depicted on a map of Switzerland (scale 1: 1,250’000). A separate text page with information is attached to the map. The publication is available at 1300 LT for the following day, and contains a date/time stamp and a version number.

DABS is not constantly updated in the case of cancellation of airspace restrictions. Please contact the Flight Information Service (FIC) or KOSIF (telephone number +41 44 813 31 10) for the latest information.
NOTAM affecting the whole Swiss territory or parts thereof such as MIL night flights are listed on the text page of the DABS only.


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 .


SmartNOTAM Database Service

The SmartNOTAM Database Service provides an up-to-date NOTAM database containing SmartNOTAM, as well as standard NOTAM, retrievable through system interfaces. This makes it easy to integrate SmartNOTAM into flight planning applications.


The SmartNOTAM Database Service offers the following features:

  • Collection of worldwide standard ICAO NOTAM
  • Processing of incoming TAM messages to SmartNOTAM for the customer-specific Coverage Area.
  • SmartNOTAM for FIR NOTAM worldwide.
  • Edited NOTAM with correct ICAO abbreviations for better readability.
  • Complete qualifier line including rectified q-codes based on the NOTAM text-enabling enhanced filtering
  • Machine-readable schedule (Item D) for time-based filtering
  • Interface to the SmartNOTAM database using XML structured messages and web services technology.


The following elements are available as options to the SmartNOTAM service:

  • Collection and processing of Domestic NOTAM.
  • Translation of SmartNOTAM from French and Spanish to English.
  • Customized processing for specific customer requirements.
  • Individual NOTAM transmission.
  • Expansion, reduction and adaptation of the coverage area after implementation.


For flight-planning software providers and software developers who wish to integrate SmartNOTAM, please contact on +41 43 931 6232, for more information.
