Yeah, right.
I know, thanks.
It is routine to turn on autoland during approach and turn it off just
before touchdown.
If you turn it off, it's not autoland.
Nope, it is an autoland approach as defined by the FAA in:
http://www.faa.gov/airports_airtraff...pubs/PCG/A.HTM
"An autoland approach is a precision instrument approach to touchdown ..."
So if you turn it off before touchdown, it's not an autoland.
You are probably confusing autoland with a coupled approach, which is
something you would have encountered if you had continued to the letter "C"
before rushing to write your post. All autolands require a coupled approach,
but a coupled approach need not include an autoland.
Since tiny tin-can aircraft don't do autolands, it's understandable that
pilots thereof might become confused.
If you try MSFS sometime (with payware add-ons), it can help clarify the
difference.
