A quantitative evaluation was made of a large number of landings in a transport airplane. Data were collected during landings with normal pilot vision, with restricted peripheral vision, and with televised view forward. Various lens focal lengths were used and camera position was changed between nose and tail locations. Data were measured in the form of ground contact g and location of touchdown point.nThe results indicated that with any of the TV displays the landing quality was inferior to that with either restricted peripheral vision or normal vision;there was greater mean error in ground contact point, but little difference in ground contact g. In general, however, it was con¬cluded that, with practice, consistently good landings can be made with this airplane when forward vision is limited to a closed-circuit TV picture if more use is made of other cockpit instrument readings than is needed for the direct forward vision landings.
