A case study of automatic landings

The case study described is over 20 years old, but it is not just of historic interest: the pioneering techniques used are still applicable and similar problems still await analysis. Above all, it is not often that one has the opportunity of looking back 20 years with the benefit of hindsight and still being able to benefit from the experience. The case study was a `safety study´, which would today be called a hazard analysis, in the form of a contract placed upon Software Sciences Ltd. The terms of reference were to accept the studies and judgements made of the airborne and ground guidance equipments and to identify, and preferably quantify, all other possible hazards to a specifically defined operation
