This paper explores the use of conjoint analysis as a measure of the subjective evaluation of clutter on avionics displays. As new systems are added to glass-cockpit aircraft they are overlaid onto existing systems and more and more symbology is present on these displays. Conjoint analysis provides an easy way to systematically analyze the clutter and to estimate what pilots will think is a cluttered display. An example of this application is provided and the results are promising.
