FOREWORD Terms of Reference 1 -. This review is the fifth in a triennial series beginning with ICAO' Circular 73-AT/10 published in .June 1965 and followed by Circular 89-AT115 in July 1968, Circular 105-AT126 in April 1971 and Circular 122-AT132 in July 1974. After examination of the second review the Sixteenth Session of the Assembly, in September 1968, expressed the view that similar documents should be produced for each major Session as background material for the work of the Economic Commission. Coverage 2. Geographically the coverage of this review extends to the whole of the Organization's membership of 135 Contracting States as of 31 December 1976. Data for those States which joined ICAO after 1965 have been included retroactively where possible. In time, the coverage extends from 1966 to 1976. It must be emphasized, however, that data for 1976 are estimated on the basis of partial reporting for that year. As regards subject, coverage extends to all activities of the scheduled airlines of Contracting States reported to ICAO for the years 1966 to 1976 and published in the statistical Series on aircraft on register, airline fleet and personnel, airline traffic, and airline financial data. The activities of the non-scheduled operators are covered less fully since data for these carriers, although supplemented from other sources, have been reported to ICAO only from 1971 and are still incomplete. Sources of information 3. In addition to the ICAO Digests of Statistics use has been made of many of the organization's economic studies, such as the earlier editions of this review, and the series of regional studies dealing with the development of international air freight and air passenger transport. Use has also been made of the Annual Reports of the Council to the Assembly for the years 1966 to 1976.

Sources of information other than ICAO, referred to in the text, include the appropriate and most recently available statistical publications of the United Nations the United Nations Conference on Trade and Development UNCTAD the European Civil Aviation Conference ECAC the Organization for Economic Cooperation and Development OECD the International Air Transport Association IATA the Association of European Airlines AEA formerly the European Airlines Research Bureau - EARB the United States Civil Aeronautics Board CAB and the World Tourism Organization WTO formerly the International Union of Official Travel Organizations - IUOTO . Second United Nations Development Decade 5. The Second United Nations Development Decade starting from 1 January 1971 was proclaimed by the Ger-era1 Assembly of the United Nations in October 1970. 11 On 21 January 1971 the Council of ICAO, at the second meeting of its seventy-second Session a Noted, and expressed its intention of taking into account, the goals and objectives set in the Strategy adopted by the General Assembly of the United Nations for the Second Development Decade b Considered that the present general rate of growth in civil aviation activities was satisfactory , that for the foreseeable future States should therefore lay emphasis rather upon increasing the efficiency of the activities and on achieving a more balanced development of all civil aviation facilities, and that the ICAO statistical programme provided an adequate means of measuring progress in the development of international civil aviation and c Emphasized that civil aviation could make a substantial contribution to development during the Second Development Decade. The present Review of the Economic Situation of Air Transport 1966-1976 covers the first six years of the Second Development Decade and thus may be taken as an interim appraisal of the development of civil aviation in the 1970s. Status 6. This Circular has been approved and is published by authority of the Secretary General. 1/ See General Assembly Resolution 2641 XXV. -
