As you may or may not know, the FCOM 1 manual can be edited by a company to suit its SOP's. This is the case with the 'certain' company that puts its WAI ON during ground operations in icing conditions. This was a decision taken with Boeing Training Standards, who have No Technical Objection to the procedure, and are happy with either way provided that NO ICE IS PRESENT ON THE WING for takeoff. Certainly this particular airlines LE will be ice free approaching the holdover time, won't it?
