ILS critical area when the tower is closed?

Not so, Steve. It can cause control problems and certainly adversely
affect an autoland. That is why your handbook contains a caveat about
such approaches.

Approach couplers and autoland systems are weather independent.~



You're mistaken. There's no need for approach couplers and autoland systems
when the weather is good. It's not a problem because the pilots can see.


FAA 7110.65
3-7-5. PRECISION APPROACH CRITICAL AREA

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.

That can only be done when the tower is open, we're talking about ILS
critical areas when the tower is closed.
