Abstract
This report presents the results of an experimental program designed to study the relative merits of a conventional moving horizon attitude director indicator (ADI), and an alternate ADI called a frequency separated display. The program is based on the investigation of the performance of naive test subjects (with no previous ADI experience) while flying a number of lateral control tasks under instrument meteorological conditions in a flight simulator set up as a T-33 jet trainer. Four lateral flying tasks were developed and employed: level tracking, heading changes, sudden attitude upsets, and unusual attitude recoveries. In addition, two secondary tasks (one audio and one visual) were employed in order to increase the overall workload and to provide a measure of level of attention required by the primary flying task. A total of 24 subjects participated in the study, with approximately 14.5 hours of simulator time each. Both objectives and subjective measurements were taken, with the independent experimental variables being: ADI type, simulator motion present/absent, and secondary task type. The experimental results indicate that ADI type was not significant in the heading changes task. TRUNCATED
