Aviation weather information in Switzerland

A small number of letters and symbols are used to present aviation weather information. Pilots learn to read and interpret these messages during their training. Nevertheless, in practice they often come across abbreviations that they are not familiar with or have forgotten. The annual brochure, Aviation Weather Information for Switzerland (PDF, 16 pages, 1.35 MB, in German and French) is helpful in this regard.

The brochure “Aviation Weather Information in Switzerland” can be ordered in print free of charge:Federal publications for private customers.

Low Level Significant Weather Chart

The Low Level Significant Weather Chart (Low-Level SWC Alps) produced jointly by Austro Control and MeteoSwiss is a combined forecast and warning map for use in aviation.
