Airframe, windshields and aircrews blades anti-ising system provides protection from icing up to ambient air temperature -30^oC, engines BMP and BNA anti-icing system - up to -40⁰C.

Airframe anti-icing system consists of air-heat system is purposed for heating a part of wing nose.

Hot air for airframe anti-icing system is taken-from 12-stage of engine compressor.

Electroheat anti-icing system is purposed for removal of ice from fin nose part, stabilized and ailerons surface.

Anti-icing system of engines BMP and BNA air intakes is air-heat. Hot air is taken from compressor 12 stage.

Windshields anti-icing system is electroheat and purposed for removal if ice by means of electric heating of crew cabin windshields. Heating elements are built - in directly to windshields. Windshields wipers for removal of water drops, melt snow and ice from windshields surface are installed on windshields.

Airscrew blades anti-icing system is electroheat and purposed for removal of ice from heated parts of blades surface. Heating elements are placed in noses of blades heated parts.

Ice detector is purposed for providing warning on ice presence on ice detector and output of commands for switching automatic operation mode of airframe, engines and aircrews anti-icing system. Controls and monitoring device of anti-icing system (UUKP-140, UUKO-140, UUKV-140) are purposed for manual and automatic controls of airframe anti-icing system, tail unit, aircrews by selected law of controls, depending on ambient air temperature, as well as for monitoring and shaping signals characterizing state of antiicing system.
