7.3.1Group frequencies can be used only if the duty to maintain continuous two−way communication with the ATC units whenever required is simultaneously fulfilled.

7.4Explanations of frequency labels

1 Channel spacing 8,33 kHz

2 Reserve

Controlled aerodromes and ATS are highlighted

7.4.1Emergency FREQ 121,500 MHz is available at all ATS units.

7.5General

7.5.1Uncontrolled low level traffic may register difficulties in establishing and maintaining radio communication with appropriate ATS units, caused by orographic specifics.

7.5.2DOC (Designated Operation Coverage)

7.5.2.1Every frequency can be used only within the Designated Operation Coverage (DOC). When a given frequency is used within the DOC, it should not be interfered and also the broadcast on a given frequency should not be the source of interference in other areas. Since the area where the CR is situated is intensely congested by frequencies, it is necessarily required to keep the defined DOC.

7.5.2.2In the airspace and at the aerodromes where ATC is not provided the appropriate frequencies are used particularly within the ATZ (see paragraph 2.4.2 of part VFR-ENR-2). It is possible to use the appropriate frequency by default in a wider area, due to reasons stated in paragraph 7.1.1.1, but at the maximum of radius 10 NM from the ARP and vertically up to the hieght 4000 ft AMSL. In exceptional cases it is possible to use within the coordinated DOC a frequency in an aera at the maximum of radius 16 NM from the ARP and up to height 3000 ft AMSL. If the airspace of class C or D or a prohibited area impinges into the DOC thus designated vertically and horizontally, the boundary of the DOC is formed by boundaries of such airspaces.

Note: DOC is designated operation coverage defined for given service type in accordance with the aviation regulation L 10. Defined DOCs are stated in Doc. 7754 FASID (ICAO-EUR).

7.5.2.3The DOC for other particular ATS airspaces (FIR, CTA, TMA, CTR) and for group frequencies is defined in AIP of the CR.

7.5.2.4Emergency FREQ 121,500 MHz is available at all ATS units.
