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.

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.

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.

You see the reasons it is required to do
autolandings in good weather (not to land the plane but for currency)
and you still can't admit you are wrong. There is a need to do
autolandings but it isn't required to safely land the plane for
that particular approach. It is simply for currency and when
the need arrises.

I had you killfiled for a while and now I gotta admit you really
provide some good entertainment. So are you the debate club captain
in the high school you attend?

I have no problem admitting when I'm wrong, but I certainly am not going to
say I'm wrong when I'm right.

Well, okay, Steve. When I flew that equipment we often did autolands in
good weather as part of the continuing certification of the system for
CAT III operations. And, an air carrier flight could be going into a
non-towered airport using the ILS when the weather is "iffy" VFR.

The "need" to use couplers and perhaps autoland systems is determined by
the carrier and it POI.

The airlines will always fly the ILS if there is one up and running.
They are required to.

Do you suppose you could cite that requirement? I've known many an airline
flight to do a visual approach when there was a perfectly good ILS approach
available.
