Well, at the risk of sounding condescending..the whole point of the PC is of course that you are not expecting the engine failure, therefore, Q.E.D, SOP apply..I ,for one, however, would not programme the "vref +50 into the box" on this occasion, as you are surely going to get the eng. failure and this only serves to F*ck up your day..use the window open method to ensure port page compliance.etc...Of course in the real world, with engine failure, and as I understand ICAo regs, actual icing conditions, which is of course most of the year in ANC, noise abatement is out the window, and you fly the standard, CX, and Boeing for that matter, LCD procedure..Hope that helps ..
