On the L-1011, DLC became operational on the selection of landing flap. The spoilers automatically set themselves to a 7 degree position and were operable automatically from 14 degrees to zero (stowed).
When on glidepath, the flight deck was in a constant position at all times, relative to the runway environment.
If the aircraft was slightly below glidepath, the spoilers would move towards the 'stowed' position, thus creating more lift, the aircraft would gently regain the glidepath without any pitch change, similarly, if one was above glidepath, the spoilers would move towards the extended position.
The autoland on the tristar was superbe. One wonders what kind of aircraft would be available today for commercial use if Lockheed had stuck to making passenger aircraft. It was a dream to fly.
