7.5 Automatic Terminal Information Service (ATIS) UK
7.5.1 To alleviate RTF loading at some busy airports, Automatic Terminal Information
Service (ATIS) messages are broadcast to pass routine arrival/departure information
on a discrete RTF frequency or on an appropriate VOR. Pilots inbound to these
airports are normally required, on first contact with the aerodrome ATSU, to
acknowledge receipt of current information by quoting the code letter of the
broadcast. Pilots of outbound aircraft are not normally required to acknowledge
receipt of departure ATIS except when requested on the actual ATIS broadcast. If,
however, pilots report receipt of a departure ATIS broadcast the QNH should be
included, thereby allowing ATC to check that the quoted QNH is up-to-the-minute.
7.5.2 Aerodromes possessing ATIS, the hours of ATIS operation and the frequency
employed are published in the UK AIP.
7.5.3 ATIS broadcasts (which should be no more than thirty seconds duration) will include
all or part of the elements of the information shown in the Manual of Air Traffic
Services Part 1, Section 3, Paragraph 11.7 in the order listed.
7.5.4 Example of ATIS broadcast:
'This is Stourton Approach Information Alpha. 0850 hours weather. Runway 28. 240
degrees 12 kt. 10 km. Intermittent slight rain. Scattered at 1000 ft, overcast at
1800 ft. Tempe12. Dew point +7. QNH 1011. Report information Alpha
received on first contact with Stourton.'
NOTES:
1) A Trend may be included in an ATIS broadcast.
2 Rapidly changing meteorological situations sometimes make it impractical to
include weather reports in the broadcast. In these circumstances, ATIS
messages will indicate that weather information will be passed on RTF.
3 Any significant change to the content of a current ATIS message will be passed
to pilots by RTF until such time as a new message is broadcast.
7.5.5 Military Weather and Aerodrome Information appear in Chapter 10 paragraph 3.3.
