I was a F/O on the first Tristar course with Goofair in the mid-70s.
ISTR it was standard practice, at the time, for us to use Cat 1 ILS runways on our network to work up the number of Autolands prior to being granted Cat 2 then ultimately Cat 3 status. I think we merely transmitted the request to ATC that we would like to perform an A/L although I don’t recollect what particular protections were put in place for our arrival.
A/Ls were a non event as far as my feeble memory recalls!
We certainly didn’t encounter any ‘Brize-type’ events!
Perhaps Basil would care to comment?

Concur.
Having come off (and then went on to), aircraft with almost zero or small touchdown bank limits, the TriStar a/l align procedure with the into-wind wing down sideslipping the rest of the approach was impressive.
I believe Lockheed employed some ex Trident designers which accounted for the amazing a/l.
One design weakness, which one of our GF colleagues demonstrated, was that an uncontained failure of #2 could take out multiple hyd systems. He certainly made the right decision that day or he'd have been up in the sky with only D Sys pressurised
