Abstract The project comprised a number of simulation exercises designed to evaluate methods of either preventing or resolving the problems likely to be caused by label overlap on Labelled Plan Displays (LPD). The automatic prevention of label overlap was investigated in ATCEU Project EU 146, (ATCEU Report No 35l). These earlier trials determined that one of the methods used, automatically alternating overlapping labels, was not suitable. The report concluded that the other methods used, machine re-positioning and reversion to a tabular display, were effective whether used separately or together, but that they should be brought into operation manually and not automatically. The exercises in EU 146 compared the amount of data v/hich controllers could extract from the LPD when the different methods of preventing overlap were used. The controllers were not exercising any control function, nor was there any other source of flight data such as a flight progress board. The project which is the subject of this report was a follow-up of the earlier trial, using manually controlled methods as had been recommended, and conducted in an active control environment. The simulation also presented an opportunity to demonstrate a new input device, the Touch Sensitive Digitiser (TSD)• This was in no way an evaluation of the device, but some observations on its use in the ATC role are included after the discussion section. The project was sponsored by the Director of Control (Plans) NATS, and carried out at the ATCEU Bournemouth (Hurn) Airport in two stages, a pilot study between 11 and 29 June and the main simulation between 13 August and 14 September 1973.
