- The point of release must be located more than 5km away from the runway of civil and military aerodromes.

Sky lanterns are not permitted in certain parts of Switzerland, including in the cities of Zurich and Bern, within a 12km radius of Basel-Mulhouse airport – and therefore in the entire canton of Basel Stadt – and in the cantons of Basel-Landschaft, Valais and Geneva. Authorisation from Skyguide is required to launch sky lanterns near aerodromes with air traffic control; within a radius of 5km of Zurich and Bern airports, authorisation is generally only granted after close of operations.
Authorisation from the FOCA, which is subject to a fee, is required if:
Requests for authorisation must be submitted by email to the FOCA at least 20 working days before the event.
Sky lanterns are, in principle, to be operated in such a way that hazards to persons, property or other aircraft are minimised and the conditions set out in Annex 2 of Implementing Regulation (EU) No 923/2012 (SERA.3140) as well as the requirements set out in Article 16 of the DETEC Ordinance on Special Category Aircraft (OSCA) are complied with.
In the event of accidents involving sky lanterns, the person who released the sky lanterns is generally liable as they are deemed to have caused damage unlawfully and in accordance with the principle of adequate causation (Article 41 of the Swiss Code of Obligations).
