Airspace class D
General
In Germany, Delta is found in the local traffic control area of less frequented commercial airports in order to keep VFR apart traffic from the usually fast, heavy, commercial instrument flight traffic when the traffic load in the airspace increases. In addition, control zones in Germany are classified exclusively as delta airspace. Airspace D is controlled airspace.
