Seven research studies and a summary paper are described in the report. The task situation is that of the helicopter pilot who must maintain visual contact with an environment outside the aircraft, and respond to turbulence and other requirements for control surface adjustments from noise and vibration cues. Time judgments of these cues were studied with findings such as follows Noise and vibration are judged about equally well in most situations noisy vs. quiet backgrounds have little effect on performance when responding to signals, pilots may over-react, or they may under-react if they initiate maneuvers. Other responses are noted and discussed with respect to vibratory and noise stimuli that could be of value, in the training of pilots for operational use of helicopters.
