“…Under low visibility conditions, wayfinding is harder, and pilots make more navigation errors than they do in clear weather conditions (McCann, Andre, Begault, Foyle, & Wenzel, 1997). The aspect of SpA that covers a pilot’s knowledge of the relative spatial and temporal location of the terrain (Bolton et al, 2007) is also dependent on the outside view and meteorological conditions (Lorenz, Kuritz-Kaiser, Schmerwitz, & Többen, 2006). More generally, other research domains have shown that performance in measures of SpK is affected by the visibility condition.…”
