ATS.TR.310 Voice-automatic terminal information service (Voice-ATIS) broadcasts

(a)Voice-automatic terminal information service (Voice-ATIS) broadcasts shall be provided at aerodromes where there is a requirement to reduce the communication load on the air traffic services VHF air-ground communication channels. When provided, they shall comprise either of the following:

(b)A discrete VHF frequency shall, whenever practicable, be used for Voice-ATIS broadcasts. If a discrete frequency is not available, the transmission may be made on the voice channel or channels of the most appropriate terminal navigation aid or aids, preferably a VOR, provided the range and readability are adequate and the identification of the navigation aid is sequenced with the broadcast so that the latter is not obliterated.

(c)Voice-ATIS broadcasts shall not be transmitted on the voice channel of an ILS.

(d)Whenever Voice-ATIS is provided, the broadcast shall be continuous and repetitive.

(e)The information contained in the current broadcast shall immediately be made known to the air traffic services unit or units concerned with the provision to aircraft of information relating to approach, landing and take-off, whenever the message has not been prepared by that unit or those units.

(f)Voice-ATIS broadcasts provided at designated aerodromes for use by international air services shall be available in the English language as a minimum
