Abstract
Preventing runway incursions is considered a top safety priority for the National Transportation Safety Board and is a growing problem among commercial air traffic at controlled airfields. This problem only increases in difficulty when the weather and airfield conditions become severely degraded. Such is the case in this Air Force Research Laboratory (AFRL) work, which focused on the decision making process of aircrew landing under near zero-zero weather at an unimproved airfield. This research is a part of a larger demonstration effort using sensor technology to land in near zero-zero weather at airfields that offer no or unreliable approach guidance. Using various head-up (HUD) and head-down (HDD) display combinations that included the sensor technology, pilot participants worked through the decision of whether the airfield was safe to land on or required a go-around. The runway was considered unsafe only if the boundary of the runway was broken by an obstacle causing an incursion. A correct decision is one that allowed the aircrew to land on a safe runway and to go-around when an incursion was present. While going around is usually considered a safe decision, in this case a false positive could have a negative mission impact by preventing subsequent landing attempts. In this study we found a combination of display formats that provided the greatest performance without making significant changes to an existing avionics suite.
