Infrastructure

Airport of Zurich

In order to function properly and safely, air transport requires an appropriate level of infrastructure. This includes aerodromes on the one hand and airspace on the other. Airspace is divided into monitored zones and non-monitored zones. In monitored airspace air traffic control guides aircraft and ensures there is adequate distance between aeroplanes.
