A Flight Information Region (FIR) is a designated volume of airspace within which air traffic services are provided. FIRs are established by the International Civil Aviation Organization (ICAO) and are used globally to manage air traffic. The primary purpose of an FIR is to ensure the safe and orderly flow of air traffic by providing air traffic control, flight information, and alerting services. Each FIR is assigned a unique name, typically based on a major city or geographical feature within its boundaries, and is managed by a specific air navigation service provider, usually a national civil aviation authority.

Within an FIR, controllers are responsible for separating aircraft from each other and from obstacles, providing information about weather, navigation, and other factors that might affect flight safety, and alerting rescue services in case of an emergency. FIRs can vary significantly in size, from small regions covering a single country to vast areas encompassing multiple nations. The boundaries of FIRs are carefully defined and often coincide with national borders, although they can also extend over international waters. The continuous provision of services within an FIR is crucial for maintaining situational awareness for pilots and controllers, thereby contributing to the overall safety of international aviation.
