Here in ARN we rarely deice the fuselage for frost, unless it has melted and run into rivelets down the fuselage. But snow is always removed. Now my question. When there is precipitation, after deicing we antice the wings and stabilisor with Type 2 100% fluid. One day a capt asked for the fuselage to be anticed also. This has only happened to me once. Usually we deice the fuselage and fin with type 1 and leave it at that. Anyone have any views on the subject. I only look after wing mounted engine aircraft so engine ingestion is not a problem. It caused quite a stir at the time because the deicing crew had never done it before and some discussion took place.
After living in a cold weather station for 15 years, you think you are good at deicing, then someone comes along with a new question.
