Abstract : Systematic man-in-the-loop simulations were conducted to evaluate pilot/system performance in the manually controlled IFR SK/FF task for the UH-1 helicopter under various operational and environmental conditions. Interpreted within the constraints imposed upon and by the simulations, the empirical results indicated that leader heading, even when perturbed by lateral gusts, was an adequate system reference; 250-2000 feet were acceptable separation distances for fixed-formation maneuvers; there were no significant performance differences between the leader or follower frame of reference; the pursuit guidance technique was applicable to the rendezvous phase; display augmentation was not required during the rendezvous, but it reduced the difficulty of the control task and improved performance; the formation grouping concept was feasible from the standpoint of display/control considerations; and the trajectory-following and pursuit guidance control techniques were both suitable for providing control commands to the pilot for formation grouping, although trajectory-following yielded better performance and pursuit guidance was easier to mechanize.
