A 727 with a form of Autoland ?
I had no idea such a model existed, ours could not even be coupled to the loc / glideslope reliably !
Autoland I wouldn't call it. It flared, but didn't decrab, then you had to disconnect once it touched down, because there was no roll-out guidance.
It was another lousy attempt by TWA to make more out of technology than was reasonable. Of course, the whores at Boeing and the FAA went along with the "program."
Shortly thereafter I went to a real CAT III airplane, the early 767.
And, many of us who scoffed at the "advanced" 727 had previous real CAT III autoland experience as F/Os on the L-1011.
