flash 2002, ILS course is derived outta DB it's the same from the PB till TD and it won't change a wee bit but of course you can check and double check it endless times if you wish. However it's stored value in the computer and doesn't change. I however admire your diligence.
Penko, isn't ILS course equal with MH in wind calm? There's your answer. The ILS course check must have some technical relevance that's what we all agree upon. ILS is stored in the DB and doesn't change in any phases of the flight thus the check must have some other background. Perhaps AI has changed all that over time with modifications however 5 degrees value is still there. Whether it's between MH ILS or GT or all of them I stand to be corrected.
