Man-in-the loop simulations were conducted to evaluate pilotsystem performance for the UH-1 helicopter under various experimental conditions. The empirical results indicated that there were no major performance differences between the IHAS and IEVD display formats although the IEVD tended to yield lower position errors and control stick rates experienced and inexperienced pilots learned the formation-flight task in a relatively short period of time when display augmentation quickening was provided approximately the same level of control precision was acquired by both groups of pilots position control performance degraded drastically when augmentation was downgraded or removed from the display the pilots could successfully leave formation with or without command information, but the maneuver was more precise with the commands and acceptable formation-flight performance was obtained with an electromechanical flight director display system although the simulated collision warning system was not capable of avoiding all collisions.
