Abstract
In a recent study of visual search, Stager and Hameluck (1986) attempted to relate the probability of detection (POD) of crash sites to operationally relevant combinations of environmental factors or contextual variables. Known (POD) values would assist in optimizing the allocation of Search and Rescue (SAR) resources during an operational search. In addition to the anticipated effects of environmental and procedural variables on visual search, it would be useful to know if measures of visual capability, such as an individual's contrast sensitivity or visual acuity, could predict potential air-to-ground detection performance. The present research was undertaken to determine whether the detection of crash sites in a simulated search task could be related to measured contrast sensitivity.
