Technical sheets

A number of initiatives to promote biodiversity have become widespread, including at airports. However, not all of these initiatives are ideal for ecosystems and certain precautions need to be taken. The STAC has produced a series of technical sheets outlining the challenges for biodiversity and the best practices associated with these initiatives.

In 2019, the French Civil Aviation Technical Center (STAC) has initiated the development of a new tool used for the elaboration of the legal constraints linked to the OLS of an aerodrome. In France, these constraints are called Plan de Servitudes Aéronautiques, or PSA.
