Evaluation of the Haworth-Newman Avionics Display Readability Scale

Abstract

This study investigates the suitability of the Haworth-Newman Display Readability Rating Scale as a performance-based test and evaluation tool. This evaluation has been necessary to determine if the scale actually measures display readability, and if consistent, reproducible results are attainable. Background information on the scale's development is presented along with a brief description of display readability characteristics. A technique for systematic degradation of display readability and a method of displaying degraded symbology sets is introduced. A flight simulation experiment was conducted to obtain performance data, Haworth-Newman readability ratings, and participants' written comments for each of the degraded symbology set levels. Five Naval test pilots attempted to maintain specified heading, altitude, and airspeed while utilizing the ten levels of symbology sets and then used the Haworth-Newman scale to rate the display readability for each. Experimental results are discussed and recommendations presented.
