AN INVESTIGATION OF SPEED AND ACCURACY IN POSITIONING MISSILE-HANDLING VEHICLES,
Abstract
The purpose of this study was to determine how fast and accurately a simulated missile-reloading vehicle could be parked next to a simulated launcher. Both track-laying vehicles and trucks were tested at night and by daylight on four types of terrain. Five accuracy envelopes were examined; the vehicles were to be parallel and no further apart than 3, 6, 12, 24 or 48 inches. The drivers performed their tasks alone, and with the help of signals from an assistant driver. Time to complete a trial increased as inter-vehicle distances (IVD) decreased. The percentage of successful trials decreased as IVDs decreased. Performance was marginally better when the drivers were guided by signals from an assistant. Performance varied only slightly according to terrain. (Author)
