From the area control centers of Geneva and Zurich, lower airspace air traffic controllers are responsible:

• for approach control activities for St.Gallen Altenrhein and Friedrichshafen (from ACC Zurich) as well as Les Eplatures and Sion (from ACC Geneva)
• as a support to ACC sectors, for special activities such as parachuting, special flights (photo flights) and IFR joinings in airspace CHARLIE. This airspace can only be entered by aircraft (mostly VFR) which communicate by radio, have a transponder, and have received clearance from air traffic control.

Through its flight information centers, skyguide also provides flight information services in the lower airspace categories GOLF and ECHO outside airport control zones and terminal areas.
