# 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

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.
