ILS critical area when the tower is closed?

It's a problem during a coupled approach especially if the pilot is
planning to do an autoland.


It's not a problem if the weather is good.

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.~

Limitations on the approach chart probably do not allow the
ILS when the tower is closed or more than one hour after the
last weather observation.

What airport are you referring to?

RW 29 at PWM has an ILS hold charted on the airport diagram, but I
don't see anything preventing it's use when the tower is closed on the
approach chart:

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.

wrong. There might be "need" to do autolanding for 3 month (?)
currency. I hear this often at night for jets going into SFO.
Granted the pilots turn off the autopilot with no loss of
safety but the need is still there.

It's not a problem because the pilots can see. The need for currency
doesn't alter the weather.

SFO has a full-time tower.

correct but there is a need to do an autoland. It is not
*required* since the weather is good enough but the
need is still there.

correct but I was referring to jets asking to do a
CAT III approach for currency even though it is VFR.

Don't be silly. There's clearly no need to do an autoland in good weather.

We're talking about ILS critical areas when the tower is closed.
