Mild Detonating Cord MDC in the next generation transparency can significantly improve aircrew ejection separation times. Embedded as quarter-inch thick lines outlining the ejection zone, the MDC explosive can rapidly fracture the boundaries of this zone in half. These sections open upward and outward as the ejection seat penetrates the canopy. MDC thus eliminates the need to jettison the canopy prior to ejection, preserving the critical escape time requisite for aircrew survival. Unfortunately, aircrew visual performance may suffer as a consequence of installing MDC. Necessarily, MDC is a canopy visual obstruction that may interfere with target detection and tracking. Consequently, it is prudent to identify and characterize the potential negative visual performance consequences of installing MDC, then minimize them prior to canopy production. This paper presents the most relevant results of an extensive search and analysis of research findings suggesting possible visual performance effects associated with canopy-embedded MDC.
