agree I exagerate
but if there is no DH you cannot continue to DH in the hope that REQUIRED rvr is attained. So the approach ban cant be applied.
the text says clearly that you may continue to DH. No mention of the no DH case. In other countries they make it very clear that. In EUOPs is not so clear.
It all comes to this question
"can you land with rvr 0/0/0, knowing that that is the rvr?"
if answer is affirm: why the 75m requirement?
if taxi and fire brigade are the reasons: Why do you disregard those reasons after passing the approach ban?
