In 2007, there were 201 airspace infringements in Swiss airspace and in airspace controlled by Switzerland. Twenty-two of these infringements occurred in the CTR and TMAs of Zurich. In the controlled airspace around Geneva there were even 36 airspace infringements. However, it is the airspace around Bern airport that registered by far the most airspace infringements. In 2007, 64 airspace intrusions were reported in the CTR and TMAs of Bern. The remaining airspace infringements occurred among the remaining regional airports and airspace intrusions in airspace C or D over FL 100 / 130.
Eight of these airspace infringements led to an Airprox where the safety of correctly flying aircraft (in five cases, commercial aircraft) was jeopardised. In 34 incidents, FOCA rated the airspace infringement as "high risk".
