Subjective LCD-CRT comparison of USAF transport aircraft cockpit electronic display formats

Abstract

This paper discusses the methods and results of a study which investigated image quality issues associated with transferring flight formats of a transport cockpit from a Cathode Ray Tube (CRT) to an Active Matrix Liquid Crystal Display (AMLCD). Eight subject pilots performed a series of flying tasks in two simulator sessions: one with a commercial grade CRT and the other with a commercial grade, prototype LCD. Subjective assessments were obtained via questionnaires that addressed image quality and useability issues. The results showed that the display formats could be implemented on the test LCD hardware with no significant degradation in image quality or usability. Some considerations for optimizing formats for LCD implementations are discussed.
