FOREWORD Introduction During the past ten years, the increase in commercial air services has continued to outstrip available capacity at more and more airports. Although many of these airports are located in Europe, there are growing numbers in other regions as well. Moreover, because of the interconnected aspect of air transport, capacity constraints at some airports impact on other airports within the international airtransport system. Environmental, economic, political and physical constraints on increasing airport capacity have, in some instances, exacerbated this problem. Governments, airlines and airports have each developed measures designed to overcome or ameliorate situations of insufficient airport capacity. However, governments are increasingly likely to face additional situations where the demand by airlines to initiate or increase commercial operations cannot be met because of a lack of airport capacity. In light of this, the ICAO Council included in the Programme Budget of fhe Organizafion for 1999-2000-2001, a study on the regulatory implications of slot allocation at airports. Scope This study concentrates on the regulatory implications of the current situation trends for airports where the demand by airlines to use the airport exceeds its capacity on a continuous basis or during peak periods the regulatory framework involved and the means by which States, airports and airlines have sought to alleviate or minimize this situation. The study also assesses current and potential mechanisms for dealing with a chronic shortage of airport capacity and suggests possible improvements of and alternatives to the existing systems. While the study addresses the linkage between airspace congestion and airport congestion, it does not address the potential issue of slot allocation for air traffic management per se, focusing on airport capacity management encompassing approach and aerodrome control, runway and terminal capacity. Sources The documents listed in the Bibliography which appears at the end of this study have been extensively referenced. The study was prepared by the ICAO Secretariat with information and assistance provided by Airports Council lnternational ACI and the International Air Transport Association IATA. A draft was reviewed by the ICAO Air Transport Committee in March 2000 and by the ICAO Conference on the Economics of Airports and Air Navigation Services in June 2000. The present text of the study takes into account comments made in the Committee and at the Conference and has been updated to reflect subsequent regulatory developments.
ii ICA 0 Circular 283-A T/119 Further work Pursuant to Recommendation 14 of the Conference on the Economics of Airports and Air Navigation Services, ICAO will undertake further work on developing guidance on procedural aspects of slot allocation with respect to equity and non-discrimination, consistent with Article 15 of the Convention on Internatonal Civil Aviation and including possible mechanisms for dispute resolution.
