    As reported by Antonov, the testing was carried out during the period from September 27th to September 30th. An-70 was fitted with new and upgraded systems: propfan engines, aircraft control system, wing-flap system intended for increasing ascensional power and crew environmental control system. The readiness of An-70 for performing the test program approved by the Ministries of Defense of Russia and Ukraine has been confirmed.

    The upgrading of An-70 included modernization of its powerplant by means of installing the modified engine and propfan control systems and the upgraded propfan in order to decrease noise level. The auxiliary power plant was replaced by a more advanced one, which is able to work under a wide range of operation conditions.

    Almost all the components of An-70’s avionics have been upgraded, including flight deck displays, due to update of element base and new mission needs. At that the mathematical models and algorithms of the aircraft control system and its components have not been changed. This solution assured the continuity of the tests performed earlier and the obtained results were recognized.
