Radio Mandatory Zone

from Wikipedia, the free encyclopedia
Radio Mandatory Zone (RMZ) around Egelsbach airfield , combined with Transponder Mandatory Zone (TMZ) and Aerodrome Traffic Zone (ATZ).
(Note: For navigation purposes, please use maps with official air traffic control imprint.)

A Radio Mandatory Zone (RMZ) is an area of ​​the air space that may only be flown with radio contact to the associated ground radio station.

purpose

At uncontrolled airfields with occasional IFR traffic , a sufficient separation of visual and instrument traffic must be ensured. Until 2014, the airspace class F (Foxtrot) existed in Germany; it prescribed certain cloud distances and minimum visibility ranges for visual air traffic, but no binding radio communication. The F airspaces were abolished in 2014 and replaced by RMZ so that visual air traffic in the airfield area can be addressed by the ground radio station, for example for information and warnings.

expansion

The lateral extension can be seen from the map material. Vertically, RMZs extend from the ground to 1000 feet (about 300 m) above the ground. Above the RMZ is lowered controlled airspace E (Echo).

regulate

In a RMZ, all aircraft are obliged to have a radiotelephone connection, including visual flights , which are otherwise exempt.

Before entering the aircraft , contact the responsible ground radio station and provide information on the aircraft type , location, altitude and flight intentions. Listening must be maintained within the RMZ, and the excursion must also be reported.

Since the responsible ground radio station is an uncontrolled airfield in airspace G (Gulf) (possibly with airfield information service " AFIS "), neither for VFR nor for IFR traffic is traffic control and separation carried out. Entry into a RMZ is not tied to a clearance.

Air traffic control clearances , if necessary, are forwarded to departing aircraft by the flight controller or AFISO after coordination with the relevant air traffic control center.
