國際航空法是與國家主權最密切相關的國際法。各主權國莫不視積極參與國際航空法之形成為確保國家利益之重要手段。惟由於台灣國際法律地位之特殊性，使得台灣無法藉由正式加入國際航空公約或組織而參與國際航空法之建構，以致這個因技術成長而快速更新的規範體系，愈益遠離我們的認知意識與實踐。如此之現象，除了在國際法上非常容易造成對國家權利狀態變化的「默認」效果外，還可能會漸漸形成某種具拘束力之國際規則，引發對領土主權管轄作非正式減讓的聯想。這種落差效果，應該不是一再宣稱為主權獨立國家的台灣所欲認同。基此，本文擬在國際航空法形成的架構下，簡述其中一個最為關鍵性的力量－國際民航組織，它的立法功能與程序，分析其正當性基礎，並就台灣在無法加入該組織之目前處境裡，如何因應這種立法功能所創設之國際航空法則及其更替增補，提出初步的分析與建議。

International air law is, among other international regulations, mostly related with state sovereignty, and is treated undeniably by every sovereign states as the indivisible facility to ensure the national interests. Due to the unique legal status, Taiwan is not allowed to participate formally with ICAO and other IGOs and their legislative process, which unavoidably resulted in an indifference in consciousness with the rapidly growing regulatory scheme. Such a practice not only creates an acquiescence to the deterioration of Taiwan's sovereignty, including the concession to state jurisdiction, but also a common consensus of the global community over her status quo, which is conceivably in contradiction with the national goal of Taiwan. Therefore, it would be feasible for this article to briefly yet systematically introduce the organization of ICAO and her law making functions so to delineate the legitimation basis of contemporary international air law. And through which may we try to figure out certain solutions to integrate and create domestic coherence with the regime for the non-members such as Taiwan.
