Radio Mandatory Zone (RMZ)

IFR arrivals and departures require increased attention in the vicinity of aerodromes, which is why so-called Radio Mandatory Zones (RMZ) have been introduced at aerodromes with IFR traffic. These are airspace class G and therefore uncontrolled.

The AIP for Germany states that aircraft intending to fly into an RMZ must make an introductory call on the published frequency to declare their intentions. In the example, the published frequency of ‘Schwäbisch Hall Information’ should be used and the following content transmitted:

• Identification of the called station
• Call sign and aircraft type
• Location, level and intentions

Pilot	DELFE, C172, 5 NM nördlich Braunsbach, 2000 Fuß, werde in die RMZ einfliegen und entlang des Kocher Richtung Süden verlassen	DELFE, C172, 5 NM north of Braunsbach, 2000 feet, will cross RMZ southbound via the River Kocher
ATC	DELFE, verstanden, QNH 1008, Verkehr, C152 im kurzen Endanflug Piste 28	DELFE, roger, QNH 1008, traffic, C152 on short final runway 28
Pilot	DELFE, QNH 1008, Verkehr in Sicht, bleibe frei	DELFE, QNH 1008, traffic in sight, will stay clear
Pilot	DELFE über Rosengarten, 2000 Fuß, hat die RMZ verlassen	DELFE over Rosengarten, 2000 feet, left the RMZ
ATC	DELFE, verstanden, tschüss	DELFE, roger, bye

During the flight through the RMZ, the pilot must continually monitor the frequency. Initiatial calls by pilots are made in the same way as traffic pattern messages and do not need to be acknowledged or confirmed by AFIS. Pilots intending to land or take off at the aerodrome will generally continue to use the shorter introductory call to establish communication.

If the corresponding AFIS position is not occupied on Vatsim, the blind messages must be made on Unicom 122.800.
