A Flight Information Region is a specific region of airspace where air traffic control services are provided. FIRs are established by countries or groups of countries and are defined by boundaries that typically follow national borders or geographical features. Each FIR is managed by a designated air traffic control center responsible for ensuring the safe and efficient flow of air traffic within its airspace.
An Upper Information Region is a specific type of FIR that encompasses the upper airspace above a certain altitude, usually above FL 245 (24,500 feet) or FL 660 (66,000 feet), depending on the country. UIRs are responsible for managing the traffic flow of high-level air traffic, including commercial airliners and military aircraft.
In general, FIRs and UIRs are important for maintaining air traffic safety by providing a structured system for managing air traffic within a defined geographic area.
