The in-flight performance of civilian instrument-rated pilots using two different types of attitude indicators in a general aviation aircraft was measured during typical instrument flying maneuvers. The instruments were an inside-out moving-horizon indicator and an outside-in moving aircraft indicator. The subjects were divided into low and high experience groups. The results of the study differ in some degree with those of some recent ground- based studies which used the same two concepts of attitude presentation. However, one result of the in-flight study agreed with many of the previous studies low time pilots exhibited a narrower range of pitch excursions with the outside-in moving aircraft attitude indicator than they did with the inside- out moving horizon indicator. When combined with the authors observations of a head-horizon tilt phenomenon relating to both humans and animals, the results of this study suggest the usefulness of a new concept for the design of the attitude indicator display. A new concept is described in the report.
