RATIONALISATION ON THE BRIDGE

Each ship must carry a basic minimum of bridge instrumentation. Therefore, it is not entirely inconceivable that in future, this will take on a definite pattern, analogous to an aircraft's blind flying panel. With the frequent changes of crew which are experienced today, a standard layout would be welcome, purely on account of the reduction in familiarisation time it would bring about. This, however, is only one of the advantages. The designer of an 'Optimum Bridge' attempts to group around the crew member, in an ergonomically suitable manner, all of the control elements and monitoring/indicating elements for which he is responsible. To simplify this design requirement, each element should comply with a standard format so as to enable it to be accommodated in the most favorable position. Indicators should be large enough to be read with ease by an operator sitting in front of them. Scale graduations, figures and legends should be marked in white on a black ground and should be illuminated from behind during darkness. Red light, having a wavelength of 660 nm, is desirable, since this has been found to have the least adverse effect on night adapted vision. Illumination should be dazzle free. Surface finishes should be non-reflective. Safeguards should be built-in to prevent inadvertent operation of controls and unauthorised interference with alarm circuits. Setting controls should be kept to a minimum. A size of 96x96 mm (frontal dimensions) would appear to be adequate for all indicators mounted on the console. Format should be uniform throughout. A commercial example of this approach is described and illustrated.
