Right, I was referring to the effects of cold soaked fuel on aerodynamic surfaces, of crouse in icing conditions. As far as I one, in these conditions, frost due to cold soaked wing is an issue on ground before departing, so de-ice needed, but what about inflight considering that most anti-ice/de-ice systems are leading edge only? The frost usually spreads on the entire surface, so would it be an issue?
