Reversion Cat111 to 11
question that has got me thinking....a quite rare occurence these days.
Is there anything that could happen on an airfield or, say to the ILS to have it downgraded from cat 111 to cat 11?....
just thinking, as i can't think of a reason why you revert to cat 11 from cat 111b on an approach....you would always go to 111a.
then again, if you were 111a to start with, can you ever have a reason to revert to cat 11?
it's just some of the manuals, state in the notes concerning LVP approaches, that "if you revert to Cat11...."
i drive a boeing if it is relevant.
any help, especially if from controllers/airfield staff would be appreciated.
...or am i just confused???........hope the query is not to confusing.
regards,
vref.
