What type of airspace exists above FL600 in the UAE?

In the context of airspace classification, the correct choice pertains to the type of airspace that exists above Flight Level 600 (FL600) in the UAE. Above this altitude, the airspace is classified as Class A.

Class A airspace is defined as controlled airspace where air traffic control (ATC) provides separation and instruction to all aircraft operating within it. This classification extends from a certain lower limit (often FL180 or higher) up to the upper limit of airspace—typically FL600 and above—where high-altitude aircraft operate, including commercial jet traffic. In this airspace, aircraft are required to operate under Instrument Flight Rules (IFR) and must be in communication with ATC, which helps to ensure safe and efficient operations given the high speeds and altitudes at which these aircraft operate.

Class E and Class G airspace, which are less structured, do not apply at such high altitudes. Class D airspace is typically used around airports with control towers and does not extend to FL600. The characteristics and operational limitations associated with Class A airspace help to maintain safety and regulatory compliance for all flights worldwide, particularly in regions with high traffic density.
