FE Hoppy, it seems you've answered your own question. Perhaps rereading the alternative methods will help. Let's consider a practical example Zurich ILS 16 CAT I approach, shall we? If you chose DA of 1590 your required MA CG is 5%, isn't it? As we saw it earlier you must be able to fly it in EO conditions, don't you? My questions is: are you gonna follow published MA in case of SE GA at DA assuming A320 performance data? Will you fly published MA in case of a GA from 100 ft AAL as well?
