Airspace classes (C, D, E, G)

    Airspace & rules

    ← All glossary terms

    European airspace is divided into classes A to G. VFR flights typically use C, D, E and G: C and D require an ATC clearance, E does not for VFR, and G is uncontrolled.

    German term
    Luftraumklassen (C, D, E, G)

    Each class defines which services ATC provides, whether radio contact is required and which VMC minima apply. Countries publish the vertical and lateral limits in their AIP and on VFR charts.

    In practice

    Brief every airspace boundary along your route, including upper and lower limits, before departure.
