You're a bit out of context. Here is the context:

b. Air carriers commonly conduct "coupled" or "autoland" operations to
satisfy maintenance, training, or reliability program requirements.
Promptly issue an advisory if the critical area will not be protected when
an arriving aircraft advises that a "coupled," "CATIII," "autoland," or
similar type approach will be conducted and the weather is reported
ceiling of 800 feet or more, and the visibility is 2 miles or more.

When the weather is good, the crew is required to advise the tower when
they intend to do an autoland or even a non-autoland coupled approach. If
the advisory you mentioned is NOT issued then the crew is trained to
expect that the tower is protecting the critical areas.


You're more than a bit out of context. There is no tower to advise as we're
talking about ILS critical areas when the tower is closed.
