Towards the end of the 20th century, an entirely new discipline emerged in aviation. An offshoot of a field known as visual science, it led aircraft engineers to change the layout of instruments in the cockpit of a fighter plane. At the breakneck speed of an aerial dogfight, a pilots ability to read their control panel might just save their life, so instrument panel layout remains a very important field.
How, for example, should we rank the altimeter in comparison to airspeed? And should either of these instruments be made more obvious than the radar? With the advent of the head-up display, the speciality changed again. Engineers had to decide which information should be projected onto a pilots visor and which instruments left on the physical control panel in front of them.
As a doctor within the NHS, I have often wished that this same ethos could be embraced by the health service. Thus far, there has been little or no progress.
