State Sovereignty Over the Airspace on the Perspective of International Air Law (A Study of the Delegation of Airspace Management of Batam and Natuna Island to Singapore)

Abstract

The issue of state sovereignty has been debated over thousands of years. International law recognizes the exclusive right of the airspace over the state’s territorial area. Its followed by the obligation to provide air navigation services on their airspace. The responsibility may be delegated by mutual agreement. The agreement may be terminated at any time. This research examines the case of the delegation of Flight Information Region (FIR) management of Batam and Natuna Island to Singapore from 1946 until 2020. Normative legal research methods are used in this research to analyze the legal issues through international treaties, legal regulations, and other literature related to FIR management. In conclusion, the delegation of the responsibility to provide air navigation services does not derogate the state’s sovereignty.
