Aeronautical Information Circulars (AICs) |

|
|
|
||
18.36 Description. AICs are a method whereby information that does not qualify for inclusion |
|
|||
(AIS) |
||||
in the AIP or is not suitable for NOTAM is disseminated to all interested parties. An AIC is |
||||
originated whenever it is desirable to promulgate: a long-term forecast of any major change in |
Service |
|||
legislation, regulations, procedures or facilities; information of a purely explanatory or advisory |
||||
nature liable to affect flight safety; or information or notification of an explanatory or advisory |
Information |
|||
|
||||
nature concerning technical, legislative or purely administrative matters. |
|
|||
18.37 General Specifications of AICs. AICs are issued in printed form, and both text and |
Aeronautical |
diagrams may be included. The originating State can select the AICs that are to be given international distribution. AICs are allocated a serial number which should be consecutive and based on the calendar year. When AICs are distributed in more than one series, each series is separately identified by a letter. It is normal for differentiation and identification of AIC topics according to subjects to use a colour coding system (i.e. the paper on which the information is published is distinguished by topic by different colour). A checklist of AIC currently in force is issued at least once a year, with distribution as for the AIC. AICs in the UK are published on Thursdays every 28 days.

Pre-flight and Post-flight Information
18.39Pre-flight Information. At any aerodrome normally used for international air operations, aeronautical information essential for the safety, regularity and efficiency of air navigation and relative to the route stages originating at the aerodrome must be made available to flight operations personnel, including flight crews and services responsible for pre-flight information. Aeronautical information provided for pre-flight planning purposes at the aerodromes must include: relevant elements of the Integrated Aeronautical Information Package; and maps and charts. The documentation may be limited to national publications and when practicable, those of immediately adjacent states, provided a complete library of aeronautical information is available at a central location and means of direct communications are available between the aerodrome AIS unit and that library.
18.40Aerodrome Information. Additional current information relating to the aerodrome of departure shall be provided concerning the following:
•Construction or maintenance work on or immediately adjacent to the manoeuvring area;
•Rough portions of any part of the manoeuvring area, whether marked or not (For example: broken parts of the surface of runways and taxiways);
•Presence and depth of snow, ice or water on runways and taxiways, including their effect on surface friction;
•Snow drifted or piled on or adjacent to runways or taxiways;
•Parked aircraft or other objects on or immediately adjacent to taxiways;
•Presence of other temporary hazards including those created by birds;
360

Aeronautical Information Service (AIS) 18
•Failure or irregular operation of part or all of the aerodrome lighting system including approach, threshold, runway, taxiway, obstruction and manoeuvring area unserviceability lights and aerodrome power supply;
•Failure, irregular operation and changes in operation status of ILS (including markers) SRE, PAR, DME, SSR, VOR, NDB, VHF aeronautical mobile channels, RVR observing system, and secondary power supply;
•Presence and operations of humanitarian relief missions, such as those undertaken under the auspices of the United Nations, together with any associated procedures, and/or limitations applied thereof.
18.41PIBs. A recapitulation of current NOTAM and other information of urgent character shall be made available to flight crews in the form of plain language pre-flight information bulletins (PIB).
18.42Post-flight Information. States shall ensure that arrangements are made to receive at aerodromes/heliports information concerning the state and operation of air navigation facilities noted by aircrews, and shall ensure that such information is made available to the aeronautical information service for such distribution as the circumstances necessitate.
