## GM1 Article 3(7)&(8) Definitions

AIRCRAFT GROUND DEICING AND ANTI ICING

ICAO Doc 9640 provides the following definitions for the terms ‘antiicing’, ‘deicing’ and ‘deicing/antiicing’.

(a) ‘Antiicing’ is a precautionary procedure by which clean aircraft surfaces are protected against the formation of ice and frost and the accumulation of snow and slush for a limited period.

(b) ‘Deicing’ is the process that removes ice, snow, slush or frost from aircraft surfaces.

(c) ‘Deicing/antiicing’ is a procedure combining both the deicing process and the antiicing process and that can be performed in one or two steps.

(1) ‘Onestep deicing/antiicing’. Heated antiicing fluid is used to deice the aircraft and remains on the surfaces to which it is applied to provide antiicing capability.

(2) ‘Twostep deicing/antiicing’. This procedure contains two distinct steps: the first step, deicing, is followed by the second step, antiicing, as a separate fluid application.
