Proficiency Maintenance and Assessment in an Instrument Flight Simulator

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.
