De-icing Conditions

Wed Nov 03, 2004 5:45 am


I was wondering what condition must exist to for ANY kind of fluid to be sprayed on the plane, whether it be deicing fluid or a something that prevents icing.

Also, what if the destination of the plane has severe icing conditions? i.e. a plane going from HNL to ANC in the dead of winter? Are any preventative measures taken then?

Normally it's visible freezing moisture.... snow, sleet, freezing rain. If its 40 degs and raining there in no need to de-ice, although some airlines and aircraft has established temperature and weather condition requirements.

As far as inbound flight to icing conditions, there is no real preparation.

On the MD80, if the temp is below 50F in high humidity, or visible precip, or frost on the bottom of the wing, a tactile inspection must be made of the top of the wing and appropriate action must be taken. Be it deice or anti-ice.

Visible precip or high humidity and close to freezing temps usually call for anti-ice.

Aircraft are anti-iced/de-iced enroute by aircraft systems. Rarely is there a concern for an aircraft flying into icing conditions, as long as the aircraft is working properly and the crew respond to the conditions properly.
