"the First Officer put IN CHARGE by the Capt to decide about de-icing" ? ? ?
WTF was the Capt thinking I wonder, or he was in the rest room ?
As the aircraft rolls gracefully over on it's back @100ft perhaps he would have cause to ponder the abdication of responsibility. There is delegation and then. . . . . something else.
Fair enough if what actually happened was that he delegated the identification of whether contamination was present to the guy doing the walkround, which may be what they meant to say, quite another if he let him make the "decision" on whether they should do something about it.
