  3. 3. January, 2006 FOREWARD Aeronautical information/data plays a vital role in the safety, regularity andefficiency of international air navigation. Aeronautical data has become more significantwith the implementation of area navigation (RNAV), required navigation performance(RNP) and sophisticated computer based air navigation systems, such as FlightManagement System (FMS). Aeronautical information/data is provided by Aeronautical Information ServicesDepartment of Airports Authority of India, through Integrated Aeronautical InformationPackage consisting of Aeronautical Information Publication (AIP), AIP Amendments,AIP Supplements, NOTAM and Pre-flight Information Bulletins (PIB) whileAeronautical Information Circulars (AIC) are published and distributed by DirectorateGeneral of Civil Aviation (DGCA). The Integrated Aeronautical Information Packageconstitutes fundamental tool for Aviation Industry as the data so published is utilized byAirlines, General Aircraft Operators, ATS Personnel, Aviation Service Providers, etc. This manual provides information, guidance and procedures for the provision ofAeronautical Information Services in conformity with ICAO Annex and Docs relevant toAIS. The parameters of Aeronautical Information Services in India harmonize with thepromulgated standards and recommended practices/procedures of ICAO. I am sure that this manual will prove useful for all AAI personnel engaged in theprovision of Aeronautical Information Services at the AIS sections of the CHQ and fieldstations. ( K. RAMALINGAM )
  4. 4. January, 2006 PREFACE Pursuant to the provision of article 37 of the Convention on International CivilAviation (Chicago 1944), each contracting state is committed to provide AeronauticalInformation Service. India being a Contracting State of ICAO, provides AeronauticalInformation Service (AIS). The AIS was initially provided by Directorate General ofCivil Aviation, India. Since 1995, DGCA and Airports Authority of India are providingAeronautical Information Service in respect of entire territory of India as well as areas inwhich India is responsible for Air Traffic Services outside its territory. AIS is provided by AAI and DGCA through publication of IntegratedAeronautical Information Package, wherein Aeronautical Information Publication (AIP),AIP Supplement, AIP Amendment and NOTAMs are published by AAI and AeronauticalInformation Circulars (AICs) are issued by DGCA. The aeronautical data, so published, is immensely utilized by Aviation ServicesProviders as the aeronautical data has grown sensitive and earned more significantimportance with technological developments with regard to sophisticated computer basedair navigation systems, such as Flight Management System (FMS). The provision of Aeronautical Information Services in India is in conformity withthe promulgated standards and recommended practices of ICAO. This manual providesguidance for the provision of Aeronautical Information Services in line with theprovisions of ICAO Annex and Docs relevant to AIS. I am sure that all the users of this manual including AAI personnel engaged in theprovision of Aeronautical Information Services will be benefited. ( P. SETH )

  8. 8. Airports Authority of India Manual of Aeronautical information services_________________________________________________________________________________ CHAPTER 1. INTRODUCTION1). The provision of aeronautical information is essential for the safety, regularity and efficiency of air navigation. The role of aeronautical information/ data has become all the more significant with the implementation of area navigation (RNAV), Required Navigation Performance (RNP) and Airborne Computer based Navigation Systems such as Flight Management System (FMS). Any error in the aeronautical information/ data can affect the safety of air navigation.2). Aeronautical information service is provided by Airports Authority of India for the whole of Indian territory and adjoining oceanic airspace over Bay of Bengal, Indian Ocean and Arabian Sea allocated to India by ICAO for the provision of Air Traffic Services.3). This manual documents information pertaining to the rules, regulation, procedures and instructions to be followed for the provision of Aeronautical Information Services by Officers & Staff working in the AIS Section of CHQ, New Delhi, International NOTAM Offices (NOF) located at Delhi, Kolkata, Mumbai & Chennai and AIS Section at other airports. AIS functions are performed by ATS/CNS personnel where the dedicated AIS staff is not posted4). Differences from ICAO Standards & Recommended practices of ICAO Annex 15 are published in AIP India.5) This manual shall not be reproduced or copied in part or full in anyway by any other organization except AAI.6). Aeronautical Information Service is provided in conformity with the following ICAO Annex and documents; 1. Annex 15 - Aeronautical Information Services. 2. DOC 8126 - Aeronautical Information Services Manual. 3. DOC 8400 - ICAO Abbreviations & Codes. 4. DOC 7383 - Aeronautical Information Service providers. 5. DOC 7910 - Location Indicators.7). This manual may be amended as and when considered appropriate. The need to amend this manual may arise because of the following reasons, (some of the parameters on account of which amendment may be considered are listed below): 1) Amendments to the applicable ICAO Annex and documents. 2) Introduction of new technologies in the provision of AIS. 3) Changes/ introduction of DGCA CARs. 4) Requirements from ATS, Airlines or any other concerned aviation agency.8). The manual will be amended by General Manager (AIS) under the authority of Executive Director (ATM) and/or Member (Operations).January, 2006 1-1
