I found that information in "Handling the big jets" by D.Davies (1971), a classic on this subject - sometimes obsolete, after more than 30 years...
High lift devices-> Complete failure case-> page 96:
Fly a low, flat final approach. On four-engined types speed control is improved by idling the outers and flying the approach on the inners only (on a three-engined type idle the centre engine). As the drag is so low there will be plenty of thrust available and larger thrust lever movements are possible without upsetting the speed.
Has anybody used this technique in the past?
