FOREWARD

Aeronautical information/data plays a vital role in the safety, regularity and
efficiency of international air navigation. Aeronautical data has become more significant
with the implementation of area navigation (RNAV), required navigation performance
(RNP) and sophisticated computer based air navigation systems, such as Flight
Management System (FMS).

Aeronautical information/data is provided by Aeronautical Information Services
Department of Airports Authority of India, through Integrated Aeronautical Information
Package consisting of Aeronautical Information Publication (AIP), AIP Amendments,
AIP Supplements, NOTAM and Pre-flight Information Bulletins (PIB) while
Aeronautical Information Circulars (AIC) are published and distributed by Directorate
General of Civil Aviation (DGCA). The Integrated Aeronautical Information Package
constitutes fundamental tool for Aviation Industry as the data so published is utilized by
Airlines, General Aircraft Operators, ATS Personnel, Aviation Service Providers, etc.

This manual provides information, guidance and procedures for the provision of
Aeronautical Information Services in conformity with ICAO Annex and Docs relevant to
AIS. The parameters of Aeronautical Information Services in India harmonize with the
promulgated standards and recommended practices/procedures of ICAO.

I am sure that this manual will prove useful for all AAI personnel engaged in the
provision of Aeronautical Information Services at the AIS sections of the CHQ and field
stations.

PREFACE

Pursuant to the provision of article 37 of the Convention on International Civil
Aviation (Chicago 1944), each contracting state is committed to provide Aeronautical
Information Service. India being a Contracting State of ICAO, provides Aeronautical
Information Service (AIS). The AIS was initially provided by Directorate General of
Civil Aviation, India. Since 1995, DGCA and Airports Authority of India are providing
Aeronautical Information Service in respect of entire territory of India as well as areas in
which India is responsible for Air Traffic Services outside its territory.

AIS is provided by AAI and DGCA through publication of Integrated
Aeronautical Information Package, wherein Aeronautical Information Publication (AIP),
AIP Supplement, AIP Amendment and NOTAMs are published by AAI and Aeronautical
Information Circulars (AICs) are issued by DGCA.

The aeronautical data, so published, is immensely utilized by Aviation Services
Providers as the aeronautical data has grown sensitive and earned more significant
importance with technological developments with regard to sophisticated computer based
air navigation systems, such as Flight Management System (FMS).

The provision of Aeronautical Information Services in India is in conformity with
the promulgated standards and recommended practices of ICAO. This manual provides
guidance for the provision of Aeronautical Information Services in line with the
provisions of ICAO Annex and Docs relevant to AIS.

I am sure that all the users of this manual including AAI personnel engaged in the
provision of Aeronautical Information Services will be benefited.

INTRODUCTION

1). 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
