Sätt och anordning för avisning av flygplan

摘要

A method and an arrangement for treating the surface (1) of an aircraft on which a layer of ice, frost or snow has formed, in order to remove such layer and possibly prevent re-freezing with e.g. glycol. According to the invention water vapour is supplied to a movable arrangement having a space (26) defined by a cloth (28) and having an opening (27) which is closed by the part of the aircraft surface being treated. The arrangement is moved along the surface of the aircraft while water vapour is supplied continuously to said space (26) via a pipe (35) so that the layer in the opening (27) melts.
