De-icing
The A-Viator, in its standard configuration, is equipped with a pneumatic de-icing system for both wing and tail leading edges and with an electrical de-icing system for propeller blades and engine nacelle air inlets.
Either a hot plate or an alcohol de- icing system can be installed on the windshield.
But no explicit about certification.
Price indication from Wiki is factor 2,5
