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.


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.
