FOREWORD Terrns of reference 1. The study that follows is a supplement to the Review of the Economic Situation of Air Transport presented to the ICAO Assembly in June 1965 and subsequently published as Circular 73-AT/ 10. In that Review paragraph 6 it was indicated that other aspects of the economic situation of air transport would be dealt with in due course, one of the aspects cited being operating costs. The Assembly agreed that economic studies of civil aviation developments should be continued as indicated in the Review and also in Council's Work Programme for the years 1966 to 1968. I- Additionally this study of air transport operating costs provides background information for work to be done on two Assembly Resolutions Al5-6 calling for the preparation of forecasts of trends and developments in civil aviation and A15-17 calling for studies on the development of air passenger travel. Sour ce s of information 2. The data on which this study is based have been drawn mainly from the Air Transport Reporting Forms filed at regular intervals by the Contracting States of ICAO, Additional information, however, has been obtained from States, airlines and air craft manufacturers, as well as from ICAO economic publications and accumulated material on the economics of air transport available at ICAO Headquarter s. The statistics refer only to the Contracting States of ICAO and when global totals or averages are given it should be noted that they exclude non-Contracting States, in particular, the USSR and the Peopley s Republic of China, Status of the study 3, This study has been prepared by the Secretariat of IGAO and is issued under the authority of the Secretary General.
