Flight levels in Russian Federation and North Korea On 5 September 2011 the government of the Russian Federation issued decree №743, pertaining to the changes in the rules of use of the country's airspace. The new rules came into force on 17 November 2011, introducing a flight level system similar to the one used in the West. RVSM has also been in force since this date. The following table is true for IFR flights: Track 180 to 359° Track 000 to 179° The new system would eliminate the need to perform climbs and descents in order to enter or leave Russian airspace from or to jurisdictions following the Western standard. From February 2017, Russia is changing to use QNH and Feet below the Transition Level. The first airport to use this is ULLI/St. Petersburg. Most other airports still use QFE. Unlike Russia, North Korea usually uses metric system below TL based on QNH.
