NITA is actively participating in the program of transition to use QNH pressure since the beginning. A large-scale update of the systems application software in terms of add-on functionality is performed for the introduction of QNH standard in terminal areas, and aeronautical information for flight procedures in the terminal areas is updated. Technical information letters are issued to upgrade the following systems operated in ATM centers: ALPHA and ALPHA-5 ATC systems, GRANIT digital recorder, and GRANIT-6 recording and playback system, EXPERT ATC simulator (versions 3 and 4) for the ATC personnel training in using QNH pressure.
Today with the new equipment installed or in the result of upgrade in compliance with the technical bulletins for ATM systems and ATC simulators readiness for operation with the use of QNH is ensured at the airfields of Syktyvkar, Nalchik, Astrakhan, Krasnodar, Anapa, Khanty-Mansiysk, Murmansk, Yuzhno-Sakhalinsk, Kurilsk (Iturup), Arkhangelsk, Ufa, Krasnoyarsk, Magadan (Sokol), Strezhev, Tomsk, Barnaul, Novokuznetsk, Gorno-Altaisk, Volgograd, Petrozavodsk, Stavropol, Magnitogorsk, Mineralnye Vody, Vologda.
In 2020 it is planned to commission a set of sites such as not limited to: Usinsk, Ukhta, Naryan-Mar, Kurgan, Izhevsk, Perm, Vaskovo (Arkhangelsk region).
A large-scale work is being carried out in the Moscow ATM Center to finalize “Moscow-Reserve” ATM system and standby complex for the introduction of new airspace structure which will result in transition to new airspace structure of Moscow ATC area by 03.12.2020 and to the use of QNH pressure in flights at the main airfields of Moscow Terminal Maneuvering Area.
Introduction of the QNH standard is intended to significantly improve safety of flights, and is aimed at eliminating hazardous situations in air traffic of foreign-made passenger aircraft.
