Aerodrome Traffic Zone (ATZ)

An Aerodrome Traffic Zone (ATZ) is intended to protect traffic around a highly frequented, uncontrolled aerodrome. As little traffic as possible should fly into the ATZ if it does not also land there. An ATZ is only active if the aerodrome in the zone is active. If it is not, the ATZ is also inactive (see AIP). An ATZ does not affect the airspace class; all rules of the airspace in which the ATZ is located still apply.

There are currently two aerodromes in Germany with an ATZ: Cochstedt and Egelbach.

Characteristics

• Entries and exits to an ATZ are only possible via specified routes; direct entry/exit is generally not possible
• Crossing an ATZ is generally prohibited
• An ATZ can also be set up temporarily. In Germany, this was the case around the Tannheim airfield at the Tannkosh Fly-In, where a large number of pilots meet at a small airfield.
