Use the ATIS, where available, to provide advance noncontrol airport/terminal area and meteorological information to aircraft.
The ATIS recording must be reviewed for completeness, accuracy, speech rate, and proper enunciation before being transmitted.
Arrival and departure messages, when broadcast separately, need only contain information appropriate for that operation.
- Identify each ATIS message by a phonetic letter code word at both the beginning and the end of the message. Automated systems will have the phonetic letter code automatically appended. Exceptions may be made where omissions are required because of special programs or equipment.
- Each alphabet letter phonetic word must be used sequentially, except as authorized in subpara a2, beginning with “Alpha,” ending with “Zulu,” and repeated without regard to the beginning of a new day. Identify the first resumed broadcast message with “Alpha” or the first assigned alphabet letter word in the event of a broadcast interruption of more than 12 hours.
- Specific sequential portions of the alphabet may be assigned between facilities or an arrival and departure ATIS when designated by a letter of agreement or facility directive.
