It is abundantly clear that improvement in regularity and safety of operations in poor visibility can only come about through increased precision during the non-visual phase of the approach and missed approach and through continuing use of the instrument guidance to the lowest possible height within the prescribed limitations during the visual phase. In common with most other airlines, B.E.A. is planning to introduce Category II operations in the near future and this paper deals with some of the problems which we have met and the way in which we plan to tackle them.

By virtue of being an exclusively short-haul airline, B.E.A. flight times are! short compared with time spent on the ground. As a result, flight schedules need to be closely integrated to provide a high rate of utilization of both aircraft and crews, and so any serious disruption of services by the weather affects B.E.A. to a greater extent than other airlines.
