Notes on routes and distances Each table is preceded by a list of notes applicable to certain distances in that table The small figures below the distance figures in the table refer to the notes vii PREFACE Supplement No.1, 1983, has been prepared by Lieutenant-Commander C J de C Scott, RN, from information received since the publication of Admiralty Distance Tables-Indian Ocean (First Edition; 1978), This supplement has been corrected to the date given below For later information see the monthly list of Corrections and Notices affecting Sailing Directions given in Section IV of the weekly editions of Admiralty Notices to Mariners Admiralty Notices to Mariners should be consulted for the monthly list of temporary and preliminary notices in force NAMES Numerous names have been altered since this volume was published To keep the amendments to a minimum this Supplement only amends the names in the Gazetteer and on the Index Chartlets In addition there is a list of Altered Names at the back of this Supplement, which should be consulted D W Haslam Rear-Admiral Hydrographer of the Navy Hydrographic Department Ministry of Defence Taunton Somerset TA 2DN 2nd April 1983 viii ... edition of Admiralty Distance Tables- Indian Ocean has been prepared by Lieutenant Commander C J de C Scott, RN, and contains distance tables for the Indian Ocean and part of the Southern Ocean from... presented in a different format from previous volumes of Admiralty Distance Tables The following volumes, or portions, of Admiralty Distance Tables are superseded Volume II Volume III 3rd Edition... 1-lndian Ocean Chart 2-Red Sea Chart 3-Persian Gulf Chart 4-Eastern Archipelago Chart 5-Seasonal Routes-North-west loose Chartlet Australian Approaches } Following page 71 ADMIRALTY INDIAN DISTANCE TABLES
