Sorry to continue hijacking the thread about the ramp checks in Switzerland…
I found an insightful PDF from our Birrfeld neighbours: Ramp inspections Vortrag
As a proper “Suisse romand” my German is not stellar but one can read on p31: “Kenntnisse über eventuelle lokale Luftraumbeschränkungen sind
notwendig. (DABS, NOTAM)” (knowledge of potential airspace restrictions is necessary/mandatory (DABS/NOTAM)) . Furthermore, the PDF-enclosed ramp check’s “Protokoll” includes KOSIF as an item, which actually refers to the national CAA’s (FOCA) coordination office for firings and safety of air navigation. I believe that KOSIF is also the former name of the DABS.
