COPYRIGHT International Civil Aviation OrganizationLicensed by Information Handling ServicesI ICAO CIRCULAR*ZLL * = 48414Lb 0004510 603 FOREWORD Introduction 1. On 1 June 1982 the Air Navigation Commi
10、ssion (100-10) examined the results of a study by the Secretariat concerning the need for the introduction in ICAO documents of international specifications for aerodrome flight information service (AFIS) as an entity of the air traffic services. 2. Following an exchange of views, the Commission dec
11、ided that international provisions and/or guidance material regarding AFIS should be formulated. It instructed the Secretary to develop detailed proposals on the I subject for further review by the Commission, taking into account the comments I made during the discussion. , 3. The guidance material
12、contained in this circular was finally developed by the Air Navigation Commission on the basis of proposals presented by the Secretariat. I Supporting reasons 4. The Statement of Basic Operational Requirements and Planning Criteria or Regional Air Navigation Meetings, as approved by the Air Navigati
13、on Commission, specifies that at aerodromes used by international general aviation where the type and density of traffic clearly do not justify the provision of aerodrome control service, the provision of aerodrome flight information service by a unit located at the aerodrome should be recommended.
14、The aerodromes in question are those designated by the letters “RG“ in ICAO air navigation plan publications. 5. The main comments made during the initial consideration by the Air Navigation Commission, as indicated in paragraph 1 above, may be summarized as follows : a) Aerodrome flight information
15、 service was being provided on a growing scale. There was a definite need for a service between aerodrome control service and no service at all. Available information showed that there were different understandings among States as to what aerodrome flight information service was. The kind of questio
16、ns which should be addressed were: 1) What is aerodrome flight information service? 2) What are its limitations? 3) What is the difference between aerodrome control service and AFIS? 4) At what aerodromes may AFIS be accepted in terms of amount of traffic, types of operation and meteorological condi
17、tions? 5) What information should be provided? 6) What should be the qualifications of AFIS officers? COPYRIGHT International Civil Aviation OrganizationLicensed by Information Handling ServicesICAO CIRCULARtZLiI tt Lld414hb 00045LS 54T (ii ICAO Circular 211-AN/128 7) What sort of facilities are req
18、uired to provide AFIU? b) The widespread provision of AFLS denonstrated a need for guidance material on the subject but not necessarily for standardization of the service. c) If an international general aviation aerodrome might be used also as an alternate for international scheduled air transport,
19、aerodrome control service should be provided at the aerodrome. 6. The guidance material on AFIS has been developed rith the intent af answering the questions in 5 a) and reflecting the thoughts in 5 b) and c) above. It includes guidance concerning the designation of AFIS aerodromes, the basic elemen
20、ts of information to be provided, the requirements of AFIS units for information and communications, equipment and facilities, the training of personnel and the procedures to be used. 7. The guidance material is intended to facilitate the task of future regional air navigation (RAN) meetings or regi
21、onal planning groups in recommending the air traffic services to be provided at international aerodromes designated for use by general aviation. It is also intended to facilitate the task of States in determining the nature and scope of the service to be provided at individual aerodromes and the inf
22、ormation to be published in their aeronautical information publications (AIPSI. It way also help to clarify in the minds of pilots the nature of the service to be expected at AFIS aerodromes. 8. It has been suggested that one of the primary motivations behind AFIS is cost/benefit end that this is no
23、t always compatible with saEety. It 1s recalled in this context that regional sir navigation plans shall satisfy the operational requirements and shall be economically justified (Assembly Resolutions A16-10 and A26-8, Appendix L, Associated Practice 5 refer). Although costs and the availability of q
24、ualified controllers are siznificant factors, it is expected that States, when determining whether aerodrome control service or aerodrome flight information service is required at a given aerodrome, will give the same weight to safety considerations a5 when they are planning other facilities and ser
25、vices. 9. It has also been suggested that the introduction of aerodrome flight information service is primarily an implementation problem. It my be noted in this regard that the Second Asia and ?acific Regional Air Navigation Meeting (Singapore, 1983) nade provision for AFT5 at various aerodroaies i
26、n the regions (Doc 9404, Agenda Item 4, Appendix A refers) arid that the European Air Navigation Plan also specifies a requirenent for tile provislon of 4FIS at a large number of aerodromes (Doc 7754, 23rd edition, Part III, Table AOP refers). The air naviwtion plans for the Africa-Indian Clcean, Ca
27、ribbean, Middle East and South American Regions contain general reconmendat ions on the subject .

34、to be used in air-ground communications. 3. Non-controlled aerodromes at which it is determined that AFIS will be provided should be identified as “AFIS aerodromes“ in order to distinguish them from controlled aerodromes.

An AFIS unit will provide flight information service and alerting service to aerodrome traffic. 5. The AFIS unit is not an a
36、ir traffic control unit. It is therefore the responsibility of pilots using the service provided by this unit to maintain proper separation in conformity with the rules of the air. Basic elements of information provided to aircraft 6. The basic elements of information to be provided to aircraft by a
