B737 NG Wing Icing
Help please from B737 NG operators:
I have noticed that a light area of ice (frost really) forms on top of the wing in the inboard aft section after the aircraft has landed. I assume (now that can be dangerous) that it is the cold fuel condensing and freezing the moisture in the air that is in contact with wing surface. I have noticed this on the underside of the wing on other aircraft types but never on the upper surface.
My question: Does this icing on the upper surface have to be removed prior to flight and if so what are the approved methods?
I have noticed this on occasion here in Australia however I am not aware of de-icing facilities (such as those in the northern hemisphere) at the major airports. Does it present any operational restrictions to NG operators in Oz.
