More notes about the Caravelle autoland here as well including a link (post 15) to a Flight magazine article of the time.

The Caravelle development team inevitably moved on to the comparable systems on Airbus, via the Dassault Mercure, which was aimed at the same fog-prone routes that those pioneer Air Inter Caravelles were assigned to. The UK Trident team were just allowed to dissipate, but it was the time that Lockheed were developing the Tristar, and I understand some of the key Trident players moved over to this programme in the USA. The Tristar, the first to get FAA autoland certification, is often described as having had an automatic landing capability which has "never been bettered".
