Transfer effects have been studied to evaluate the suitability of a high fidelity flight simulator (Device 2B24) for maintaining and assessing instrument proficiency among experienced Army helicopter pilots. Evidence in support of positive transfer was obtained by comparing pilots trained in the simulator with pilots trained in the aircraft (UH-1H) and with pilots trained in both. In addition, performance evaluation in the simulator accurately predicted performance in the aircraft. This study suggests that simulators of proven effectiveness can be used both to maintain and assess the proficiency of experienced pilots.

Twenty subjects were shown a film containing 54 presentations of a moving standard disc followed immediately by one of six well-known target objects moving at the identical velocity. The subjects were asked to judge the speed of the target in relation to the standard. Judgments were made in arbitrary numbers from 0-50 to enable calculation of error magnitude as well as direction. It was hypothesized that objects which are known to move fast would be overestimated in relation to the standard while objects known to move slow would be underestimated. The results did not fully support the hypotheses. However, they did point up a need for research into the possible existence of differential modes of perception mediated by changes in objective speed of the target.
