Which flight levels define the Upper Information Region (UIR) in the UAE?

The Upper Information Region (UIR) is established for airspace management purposes. In the context of the UAE, the UIR specifically refers to the altitude starting from Flight Level 145 (FL145) and extending onwards to Flight Level 600 (FL600). This range allows for the effective management of high-altitude air traffic, offering a structured environment for both commercial and general aviation activities.

Flight Level 145 serves as the lower boundary, where aircraft operating above this level will transition into the UIR, ensuring that they are under the necessary air traffic control regulations suitable for high-altitude operations. The upper boundary of FL600 allows for significant vertical spacing between high-altitude flights, which is crucial for safety and proper navigation in the increasingly busy airspace.

This division of airspace is vital for coordinating flights safely and efficiently, providing clear categorization for both controlled and uncontrolled airspaces as flights reach higher altitudes. Understanding this definition is crucial for anyone involved in aviation law or operations within the UAE airspace, as it directly affects air traffic management and safety protocols.
