Some big changes came into effect in Uzbekistan on October 2. The country has officially dropped its old “UT” ICAO prefix in favor of “UZ”.<\/strong><\/p>\n

So the Tashkent FIR is now UZTR (was UTTR), and the Samarkand FIR is now UZSD (was UTSD). The same applies to all airports: Tashkent becomes UZTT, Samarkand is now UZSS, Bukhara is UZSB, and so on.<\/p>\n

According to UzAeroNavigation<\/a>, the national ANSP, this is part of a wider modernization effort – giving Uzbekistan\u2019s airspace a clearer, more distinct identity<\/strong> and moving away from the legacy Soviet-era \u201cUT\u201d codes.<\/p>\n

At the same time, Uzbekistan has introduced a unified transition altitude of 13,000 ft and transition level of FL150<\/strong> (previously 6,000 ft \/ FL080), bringing it more in line with its Central Asian neighbors and hopefully making level changes at FIR boundaries a bit smoother.<\/p>\n

The higher setting means crews will stay on local pressure a bit longer when climbing out from airports like UZTT\/Tashkent and UZSS\/Samarkand<\/strong>, which sit close to mountainous terrain – helping with altitude awareness until they\u2019re well clear.<\/p>\n

\"\"<\/p>\n

Uzbekistan handles a steady stream of east-west overflights linking Europe with China, Hong Kong, South Korea, and Japan.<\/strong> These routes have become even more important since 2022, as many operators continue to avoid Russian airspace, routing instead through Kazakhstan, Uzbekistan, and Turkmenistan on their way to and from Asia.<\/p>\n

\"\"<\/p>\n

One important heads-up: the new \u201cUZ\u201d ICAO addresses have been published, but they\u2019re not active for flight plan filing yet<\/strong>.<\/p>\n

\"\"<\/p>\n

For now, keep using the old \u201cUT\u201d AFTN addresses for everything<\/strong> \u2014 flight plans, messages, permits, and so on. For example, file to UTTRZQZX for the Tashkent FIR (not UZTRZQZX).<\/p>\n

According to UZTR Notam D0922\/25, the switch to the new addresses won\u2019t take effect until 29 Oct 2025, so stick with the old ones until then (or until further notice).<\/p>\n
